In the 2004 Tony Award-winning musical Avenue Q, the lead character sings a song about finding his purpose in life: “I don’t know how I know, but I’m gonna find my purpose. I don’t know where I’m gonna look, but I’m gonna find my purpose.” Although the song is about life in general, the lyrics are also appropriate when thinking about the purpose of your speech. You may know that you have been assigned to deliver a speech, but finding a purpose and topic seems like a formidable task. You may be asking yourself questions like, “What if the topic I pick is too common?”; “What if no one is interested in my topic?”; “What if my topic is too huge to cover in a three- to five-minute speech?”; or many others.
Finding a speech’s purpose and topic isn’t as complex or difficult as you might believe. This may be hard to accept right now but trust us. After you read this chapter, you’ll understand how to go about finding interesting topics for a variety of different types of speeches. In this chapter, we are going to explain how to identify the general purpose of a speech. We will also discuss how to select a topic, what to do if you’re just drawing a blank, and four basic questions you should ask yourself about the speech topic you ultimately select. Finally, we will explain how to use your general purpose and your chosen topic to develop the specific purpose and thesis of your speech.
General Purpose
What do you think of when you hear the word “purpose”? Technically speaking, a purpose is why something exists, how we use an object, or why we make something. For the purposes of public speaking, all three can be applied. For example, when we talk about a speech’s purpose, we can question why a specific speech was given, how we are supposed to use the information within a speech, and why we are personally creating a speech. For this specific chapter, we are more interested in that last aspect of the definition of the word “purpose”: why we give speeches.
Ever since scholars started writing about public speaking as a distinct phenomenon, there have been a range of different systems created to classify the types of speeches people may give. Aristotle talked about three speech purposes: deliberative (political speech), forensic (courtroom speech), and epideictic (speech of praise or blame). Cicero also talked about three purposes: judicial (courtroom speech), deliberative (political speech), and demonstrative (ceremonial speech—similar to Aristotle’s epideictic). A little more recently, St. Augustine of Hippo also wrote about three specific speech purposes: to teach (provide people with information), to delight (entertain people or show people false ideas), and to sway (persuade people to a religious ideology). All these systems of identifying public speeches have been attempts at helping people determine the general purpose of their speech. A general purpose refers to the broad goal of creating and delivering a speech.
These typologies or classification systems of public speeches serve to demonstrate that general speech purposes have remained pretty consistent throughout the history of public speaking. Modern public speaking scholars typically use a classification system for three general purposes: to inform, to persuade, and to entertain.
A general purpose refers to the broad goal of creating and delivering a speech.
To Inform
The first general purpose that some people have for giving speeches is to inform. Simply put, informative speaking is about helping audience members acquire information that they do not already possess. Audience members can then use this information to understand something (e.g. a speech on a new technology or a speech on an issue of community concern) or to perform a new task or improve their skills (e.g. a speech on how to swing a golf club or a speech on how to assemble a layer cake). The most important characteristic of informative topics is that the goal is to gain knowledge. Notice that the goal is not to encourage people to use that knowledge in any specific way. When a speaker starts encouraging people to use knowledge in a specific way, they are no longer informing but instead persuading.
Informative speaking is about helping audience members acquire information that they do not already possess.
Let’s look at a real example of how an individual can accidentally go from informing to persuading. Let’s say you are assigned to inform an audience about a new vaccination program. In an informative speech, the purpose of the speech is to explain to your audience what the program is and how it works. If, however, you start encouraging your audience to participate in the vaccination program, you are no longer informing them about the program but instead persuading them to become involved in the program. One of the most common mistakes new public speaking students make is to blur the line between informing and persuading.
Why We Share Knowledge
Knowledge sharing is the process of delivering information, skills, or expertise in some form to people who could benefit from it. Every year, millions of people attend some kind of knowledge sharing conference or convention in hopes of learning new information or skills that will help them in their personal or professional lives (Atwood, 2009).
People are motivated to share their knowledge with other people for a variety of reasons (Hendriks, 1999). For some, the personal sense of achievement or responsibility drives them to share their knowledge (internal motivational factors). Others are compelled to share knowledge because of the desire for recognition or the possibility of job enhancement (external motivational factors). Knowledge sharing is an integral part of every society, so learning how to deliver informative speeches is a valuable skill.
Knowledge sharing is the process of delivering information, skills, or expertise in some form to people who could benefit from it.
Common Types of Informative Topics
O’Hair, Stewart, and Rubenstein identified six general types of informative speech topics: objects, people, events, concepts, processes, and issues (O’Hair, et al., 2007). The first type of informative speech relates to objects, which can include how objects are designed, how they function, and what they mean. For example, a student of one of our coauthors gave a speech on the design of corsets, using a mannequin to demonstrate how corsets were placed on women and the amount of force necessary to lace one up.
The second type of informative speech focuses on people. People-based speeches tend to be biography-oriented. Such topics could include recounting an individual’s achievements and explaining why he or she is important in history. Some speakers, who are famous themselves, will focus on their own lives and how various events shaped who they ultimately became. Dottie Walters noted as being the first female in the United States to run an advertising agency. In addition to her work in advertising, Dottie also spent a great deal of time as a professional speaker. She often would tell the story about her early years in advertising when she would push around a stroller with her daughter inside as she went from business to business trying to generate interest in her copywriting abilities. You don’t have to be famous, however, to give a people-based speech. Instead, you could inform your audience about a historical or contemporary hero whose achievements are not widely known.
The third type of informative speech involves explaining the significance of specific events, either historical or contemporary. For example, you could deliver a speech on a particular battle of World War II or a specific presidential administration. If you’re a history buff, event-oriented speeches may be right up your alley. There are countless historical events that many people aren’t familiar with and would find interesting. You could also inform your audience about a more recent or contemporary event. Some examples include concerts, plays, and arts festivals; athletic competitions; and natural phenomena, such as storms, eclipses, and earthquakes. The point is to make sure that an informative speech is talking about the event (who, what, when, where, and why) and not attempting to persuade people to pass judgment upon the event or its effects.
The fourth type of informative speech involves concepts, or “abstract and difficult ideas or theories” (O’Hair, et al., 2007). For example, if you want to explain a specific communication theory, E. M. Griffin provides an excellent list of communication theories on his website, http://www.afirstlook.com/main.cfm/theory_list. Whether you want to discuss theories related to business, sociology, psychology, religion, politics, art, or any other major area of study, this type of speech can be very useful in helping people to understand complex ideas.
The fifth type of informative speech involves processes. The process speech can be divided into two unique types: how-it-functions and how-to-do. The first type of process speech helps audience members understand how a specific object or system works. For example, you could explain how a bill becomes a law in the United States. There is a very specific set of steps that a bill must go through before it becomes a law, so there is a very clear process that could be explained to an audience. The how-to-do speech, on the other hand, is designed to help people come to an end result of some kind. For example, you could give a speech on how to quilt, how to change a tire, how to write a résumé, and millions of other how-to oriented topics. In our experience, the how-to speech is probably the most commonly delivered informative speech in public speaking classes.
The final type of informative speech involves issues, or “problems or matters of dispute” (O’Hair, et al., 2007). This informative speech topic is probably the most difficult for novice public speakers because it requires walking a fine line between informing and persuading. If you attempt to deliver this type of speech, remember the goal is to be balanced when discussing both sides of the issue. To see an example of how you can take a very divisive topic and make it informative, check out the series Point/Counterpoint published by Chelsea House, http://chelseahouse.infobasepublishing.com. This series of books covers everything from the pros and cons of blogging to whether the United States should have mandatory military service.
Sample: Jessy Ohl’s Informative Speech
The following text represents an informative speech prepared and delivered by an undergraduate student named Jessy Ohl. While this speech is written out as a text for purposes of analysis, in your public speaking course, you will most likely be assigned to speak from an outline or notes, not a fully written script. As you read through this sample speech, notice how Ms. Ohl uses informative strategies to present the information without trying to persuade her audience.
In 1977, a young missionary named Daniel Everett traveled deep into the jungles of Brazil to spread the word of God. However, he soon found himself working to translate the language of a remote tribe that would ultimately change his faith, lead to a new profession, and pit him in an intellectual fistfight with the world-famous linguist Noam Chomsky. As New Scientist Magazine of January 2008 explains, Everett’s research on a small group of 350 people called the Pirahã tribe has revealed a language that has experts and intellectuals deeply disturbed.
While all languages are unique, experts like Noam Chomsky have argued that they all have universal similarities, such as counting, that are hard-wired into the human brain. So as National Public Radio reported on April 8, 2007, without the ability to count, conceptualize time or abstraction, or create syntax, the Pirahã have a language that by all accounts shouldn’t exist.
Daniel Everett is now a professor of linguistics at Illinois State University, and he has created controversy by calling for a complete reevaluation of all linguistic theory in light of the Pirahã. Exploration of the Pirahã could bring further insight into the understanding of how people communicate and even, perhaps, what it means to be human. Which is why we must: first, examine the unique culture of the Pirahã; second, explore what makes their language so surprising; and finally, discover the implications the Pirahã have for the way we look at language and humanity.
Taking a closer look at the tribe’s culture, we can identify two key components of Pirahã culture that help mold language: first, isolation; and second, emphasis on reality.
First, while globalization has reached nearly every corner of the earth, it has not been able to penetrate the Pirahã natives in the slightest. As Dr. Everett told the New Yorker of April 16, 2007, no group in history has resisted change like the Pirahã. “They reject everything from outside their world” as unnecessary and silly. Distaste for all things foreign is the reason why the people have rejected technology, farming, religion, and even artwork.
The lack of artwork illustrates the second vital part of Pirahã culture: an emphasis on reality. According to the India Statesman of May 22, 2006, all Pirahã understanding is based around the concept of personal experience. If something cannot be felt, touched, or experienced directly then to them, it doesn’t exist, essentially eliminating the existence of abstract thought. Since art is often a representation of reality, it has no value among the people. During his work as a missionary, Everett was amazed to find that the natives had no interest in the story of Jesus once they found out that he was dead. The Pirahã psyche is so focused on the present that the people have no collective memory, history, written documents, or creation myths. They are unable to even remember the names of dead grandparents because once something or someone cannot be experienced, they are no longer important.
Since his days as a missionary, Everett remains the only Western professor able to translate Pirahã. His research has discovered many things missing with the language: words for time, direction, and color. But more importantly, Pirahã also lacks three characteristics previously thought to be essential to all languages: complexity, counting, and recursion.
First, the Pirahã language seems incredibly simple. Now, this isn’t meant to imply that the people are uncivilized or stupid, but instead, they are minimalist. As I mentioned earlier, they only talk in terms of direct experience. The London Times of January 13, 2007, notes that with only eight consonants and three vowels, speakers rely on the use of tone, pitch, and humming to communicate. In fact, Pirahã almost sounds more like song than speech.
Second, Noam Chomsky’s famous universal grammar theory includes the observation that every language has a means of counting. However, as reported in the June 2007 issue of Prospect Magazine, the Pirahã only have words for “one, two, and MANY.” This demonstrates the Pirahã’s inability to conceptualize a difference between three and five or three and a thousand. Dr. Everett spent six months attempting to teach even a single Pirahã person to count to ten, but his efforts were in vain, as tribal members considered the new numbers and attempts at math “childish.”
Third, and the biggest surprise for researchers, is the Pirahã’s apparent lack of recursion. Recursion is the ability to link several thoughts together. It is characterized in Christine Kenneally’s 2007 book, The Search for the Origins of Language, as the fundamental principle of all language and the source of limitless expression. Pirahã is unique since the language does not have any conjunctions or linking words. Recursion is so vital for expression that the Chicago Tribune of June 11, 2007, reports that a language without recursion is like disproving gravity.
Although the Pirahã don’t care what the outside world thinks of them, their language and world view has certainly ruffled feathers. And while civilization hasn’t been able to infiltrate the Pirahã, it may ultimately be the Pirahã that teaches civilization a thing or two, which brings us to implications on the communicative, philosophical, and cultural levels. By examining the culture, language, and implications of the Pirahã tribe we are able to see how this small Brazilian village could shift the way that we think and talk about the world. Daniel Everett’s research hasn’t made him more popular with his colleagues. But his findings do show that more critical research is needed to make sure that our understanding of language is not lost in translation.
To Persuade
The second general purpose people can have for speaking is to persuade. In persuasive speaking, we attempt to get listeners to embrace a point of view or to adopt a behavior that they would not have done otherwise. A persuasive speech is distinguished from an informative speech by the fact that it includes a call for action for the audience to make some change in their behavior or thinking.
Why We Persuade
The reasons behind persuasive speaking fall into two main categories, which we will call “pure persuasion” and “manipulative persuasion.” Pure persuasion occurs when a speaker urges listeners to engage in a specific behavior or change a point of view because the speaker truly believes that the change is in the best interest of the audience members. For example, you may decide to give a speech on the importance of practicing good oral hygiene because you genuinely believe that oral hygiene is essential and that bad oral hygiene can lead to a range of physical, social, and psychological problems. In this case, the speaker has no ulterior or hidden motive (e.g. you are not a toothpaste salesperson).
Manipulative persuasion occurs when a speaker urges listeners to engage in a specific behavior or change a point of view by misleading them, often to fulfill an ulterior motive beyond the face value of the persuasive attempt. We call this form of persuasion manipulative because the speaker is not being honest about the real purpose of attempting to persuade the audience. Ultimately, this form of persuasion is perceived as profoundly dishonest when audience members discover the ulterior motive. For example, suppose a physician who also owns a large amount of stock in a pharmaceutical company is asked to speak before a group of other physicians about a specific disease. Instead of informing the group about the illness, the doctor spends the bulk of his time attempting to persuade the audience that the drug his company manufactures is the best treatment for that specific disease.
Obviously, the critical question for persuasion is the speaker’s intent. Is the speaker attempting to persuade the audience because of a sincere belief in the benefits of a certain behavior or point of view? Or is the speaker using all possible means—including distorting the truth—to persuade the audience because they will derive personal benefits from their adopting a specific behavior or point of view? Unless your speech assignment calls explicitly for a speech of manipulative persuasion, the usual (and ethical) understanding of a “persuasive speech” assignment is that you should use the pure form of persuasion.
Persuasive speaking attempts to get listeners to embrace a point of view or to adopt a behavior that they would not have done otherwise.
Pure persuasion occurs when a speaker urges listeners to engage in a specific behavior or change a point of view because the speaker truly believes that the change is in the best interest of the audience members.
Manipulative persuasion occurs when a speaker urges listeners to engage in a specific behavior or change a point of view by misleading them, often to fulfill an ulterior motive beyond the face value of the persuasive attempt.
Persuasion: Behavior versus Attitudes, Values, and Beliefs
Persuasion can address behaviors, observable actions on the part of listeners, and it can also address intangible thought processes in the form of attitudes, values, and beliefs.
When the speaker attempts to persuade an audience to change their behavior, or observable actions on the part of listeners. We can often observe and even measure how successful the persuasion was. For example, after a speech attempting to persuade the audience to donate money to a charity, the charity can measure how many donations were received. The following is a short list of various behavior-oriented persuasive speeches we’ve seen in our own classes: washing one’s hands frequently and using hand sanitizer, adapting one’s driving habits to improve gas mileage, using open-source software, or drinking one soft drink or soda over another. In all these cases, the goal is to make a change in the basic behavior of audience members.
The second type of persuasive topic involves a change in attitudes, values, or beliefs. An attitude is defined as an individual’s general predisposition toward something as being good or bad, right or wrong, negative or positive. If you believe that dress codes on college campuses are a good idea, you want to give a speech persuading others to adopt a positive attitude toward campus dress codes.
A speaker can also attempt to persuade listeners to change some value they hold. Value refers to an individual’s perception of the usefulness, importance, or worth of something. We can value a college education, we can value technology, and we can value freedom. Values, as a general concept, are relatively ambiguous and tend to be very lofty ideas. Ultimately, what we value in life motivates us to engage in a range of behaviors. For example, if you value protecting the environment, you may recycle more of your trash than someone who does not hold this value. If you value family history and heritage, you may be more motivated to spend time with your older relatives and ask them about their early lives than someone who does not hold this value.
Lastly, a speaker can attempt to persuade people to change their personal beliefs. Personal beliefs are propositions or positions that an individual holds as true or false without positive knowledge or proof. Typically, beliefs are divided into two basic categories: core and dispositional. Core beliefs are beliefs that people have actively engaged in and created over the course of their lives (e.g. belief in a higher power, belief in extraterrestrial life forms). Dispositional beliefs, on the other hand, are beliefs that people have not actively engaged in; they are judgments based on related subjects, which people make when they encounter a proposition. Imagine, for example, that you were asked the question, “Can gorillas speak English?” While you may never have met a gorilla or even seen one in person, you can make instant judgments about your understanding of gorillas and fairly certainly say whether you believe that gorillas can speak English.
When it comes to persuading people to alter beliefs, persuading audiences to change core beliefs is more difficult than persuading audiences to alter dispositional beliefs. If you find a topic related to dispositional beliefs, using your speech to help listeners alter their processing of the belief is a realistic possibility. But as a novice public speaker, you are probably best advised to avoid core beliefs. Although core beliefs often appear to be more exciting and interesting than dispositional ones, you are very unlikely to alter anyone’s core beliefs in a five- to ten-minute classroom speech.
Attitude is defined as an individual’s general predisposition toward something as being good or bad, right or wrong, negative or positive.
Value refers to an individual’s perception of the usefulness, importance, or worth of something.
Core beliefs are beliefs that people have actively engaged in and created over the course of their lives (e.g. belief in a higher power, belief in extraterrestrial life forms).
Dispositional beliefs are beliefs that people have not actively engaged in; they are judgments based on related subjects, which people make when they encounter a proposition.
Sample: Jessy Ohl’s Persuasive Speech
The following speech was written and delivered by an undergraduate student named Jessy Ohl. As with our earlier example, while this speech is written out as a text for purposes of analysis, in your public speaking course, you will most likely be assigned to speak from an outline or notes, not a fully written script.
Take a few minutes and compare this persuasive speech to the informative speech Ms. Ohl presented earlier in this chapter. What similarities do you see? What differences do you see? Does this speech seek to change the audience’s behavior? Attitudes? Values? Dispositional or core beliefs? Where in the speech do you see one or more calls for action?
With a declining population of around 6,000, my home town of Denison, Iowa, was on the brink of extinction when a new industry rolled in bringing jobs and revenue. However, as the Canadian Globe and Mail of July 23, 2007, reports, the industry that saved Denison may ultimately lead to its demise.
Denison is one of 110 communities across the country to be revolutionized by the production of corn ethanol. Ethanol is a high-powered alcohol, derived from plant matter, that can be used like gasoline. According to the Omaha World Herald of January 8, 2008, our reliance on foreign oil combined with global warming concerns have many holding corn ethanol as our best energy solution. But despite the good intentions of helping farmers and lowering oil consumption, corn ethanol is filled with empty promises. In fact, The Des Moines Register of March 1, 2008, concludes that when ethanol is made from corn, all of its environmental and economic benefits disappear. With oil prices at 100 dollars per barrel, our nation is in an energy crisis, and luckily, the production of ethanol can be a major help for both farmers and consumers, if done correctly. Unfortunately, the way we make ethanol—over 95% from corn—is anything but correct. Although hailed as a magic bullet, corn ethanol could be the worst agricultural catastrophe since the Dust Bowl.
The serious political, environmental, and even moral implications demand that we critically rethink this so-called yellow miracle by: first, examining the problems created by corn ethanol; second, exploring why corn ethanol has gained such power; and finally, discovering solutions to prevent a corn ethanol disaster.
Now, if you have heard anything about the problems of corn ethanol, it probably dealt with efficiency. As the Christian Science Monitor of November 15, 2007, notes, it takes a gallon of gasoline or more to make a gallon of ethanol. And while this is an important concern, efficiency is the least of our worries. Turning this crop into fuel creates two major problems for our society: first, environmental degradation; and second, acceleration of global famine.
First, corn ethanol damages the environment as much as, if not more than, fossil fuels. The journal Ethanol and Bio-diesel News of September 2007 asserts that the production of corn ethanol is pushing natural resources to the breaking point. Since the Dust Bowl, traditional farming practices have required farmers to “rotate” crops. But with corn ethanol being so profitable, understandably, farmers have stopped rotating crops, leading to soil erosion, deforestation, and fertilizer runoff—making our soil less fertile and more toxic. And the story only gets worse once the ethanol is manufactured. According to National Public Radio’s Talk of the Nation of February 10, 2008, corn ethanol emits more carbon monoxide and twice the amount of carcinogens into the air as traditional gasoline.
The second problem created from corn ethanol is the acceleration of global famine. According to the US Grains Council, last year, 27 million tons of corn, traditionally used as food, was turned into ethanol, drastically increasing food prices. The March 7, 2007, issue of The Wall Street Journal explains that lower supplies of corn needed for necessities such as farm feed, corn oil, and corn syrup have increased our food costs in everything from milk to bread, eggs, and even beer as much as 25 percent. The St. Louis Post Dispatch of April 12, 2007, reports that the amount of corn used to fill one tank of gas could feed one person for an entire year. In October, Global protests over corn ethanol lead the United Nations to call its production “a crime against humanity.”
If you weren’t aware of the environmental or moral impacts of corn ethanol, you’re not alone. The Financial Times of May 27, 2007, reports that the narrative surrounding corn ethanol as a homegrown fuel is so desirable that critical thinking is understandably almost nonexistent. To start thinking critically about corn ethanol, we need to examine solutions on both the federal and personal levels.
First, at the federal level, our government must end the ridiculously high subsidies surrounding corn ethanol. On June 24, 2007, The Washington Post predicted that subsidies on corn ethanol would cost the federal government an extra 131 billion dollars by 2010.
This isn’t to say that the federal government should abandon small farmers. Instead, let’s take the excitement around alternative fuels and direct it toward the right kinds of ethanol. The Economist of June 2, 2007, reports that other materials such as switch grass and wood chips can be used instead of corn. And on July 6, 2011, The New York Times reported on ethanol made from corn cobs, leaves, and husks, which leaves the corn kernels to be used as food. The government could use the money paid in subsidies to support this kind of responsible production of ethanol. The point is that ethanol done right can honestly help with energy independence.
On the personal level, we have all participated in the most important step, which is being knowledgeable about the true face of corn ethanol. However, with big business and Washington proclaiming corn ethanol’s greatness, we need to spread the word. So please, talk to friends and family about corn ethanol while there is still time. To make this easier, visit my website, at http://www.responsibleethanol.com. Here you will find informational materials, links to your congressional representatives, and ways to invest in switch grass and wood ethanol.
Today, we examined the problems of corn ethanol in America and discovered solutions to make sure that our need for energy reform doesn’t sacrifice our morality. Iowa is turning so much corn into ethanol that soon the state will have to import corn to eat. And while my hometown of Denison has gained much from corn ethanol, we all have much more to lose from it.
To Entertain
The final general purpose people can have for public speaking is to entertain. Whereas informative and persuasive speech making is focused on the end result of the speech process, entertainment speaking focuses on the theme and occasion of the speech. An entertaining speech can be either informative or persuasive at its root, but the context or theme of the speech requires speakers to think about the speech primarily in terms of audience enjoyment.
Why We Entertain
Entertaining speeches are very common in everyday life. The fundamental goal of an entertaining speech is audience enjoyment, which can come in a variety of forms. Entertaining speeches can be funny or serious. Overall, entertaining speeches are not designed to give an audience a deep understanding of life but instead to function as a way to divert an audience from their day-to-day lives for a short period of time. This is not to say that an entertaining speech cannot have real content that is highly informative or persuasive, but its goal is primarily about the entertaining aspects of the speech and not focused on the informative or persuasive quality of the speech.
Common Forms of Entertainment Topics
There are three basic types of entertaining speeches: the after-dinner speech, the ceremonial speech, and the inspirational speech. The after-dinner speaking is a form of speaking where a speaker takes a serious speech topic (either informative or persuasive) and injects a level of humor into the speech to make it entertaining. Some novice speakers will attempt to turn an after-dinner speech into a stand-up comedy routine, which doesn’t have the same focus (Roye, 2010). After-dinner speeches are first and foremost speeches.
A ceremonial speech is a type of entertaining speech where the specific context of the speech is the driving force of the speech. Common types of ceremonial speeches include introductions, toasts, and eulogies. In each of these cases, there are specific events that drive the speech. Maybe you’re introducing an individual who is about to receive an award, giving a toast at your best friend’s wedding, or delivering the eulogy at a relative’s funeral. In each of these cases, the speech and the purpose of the speech is determined by the context of the event and not by the desire to inform or persuade.
The final type of entertaining speech, an inspirational speech, is one where the speaker’s primary goal is to inspire her or his audience. Inspirational speeches are based on emotions with the goal to motivate listeners to alter their lives in some significant way. Florence Littauer, a famous professional speaker, delivers an emotionally charged speech titled “Silver Boxes.” In the speech, Mrs. Littauer demonstrates how people can use positive comments to encourage others in their daily lives. The title comes from a story she tells at the beginning of the speech where she was teaching a group of children about using positive speech, and one of the children defined positive speech as giving people little silver boxes with bows on top (http://server.firefighters.org/catalog/2009/45699.mp3).

Sample: Adam Fink’s Entertainment Speech
The following speech, by an undergraduate student named Adam Fink, is an entertainment speech. Specifically, this speech is a ceremonial speech given at Mr. Fink’s graduation. As with our earlier examples, while this speech is written out as a text for purposes of analysis, in your public speaking course you will most likely be assigned to speak from an outline or notes, not a fully written script. Notice that the tenor of this speech is persuasive, but it persuades in a more inspiring way than just building and proving an argument.
Good evening! I’ve spent the last few months looking over commencement speeches on YouTube. The most notable ones had eight things in common. They reflected on the past, pondered about the future. They encouraged the honorees. They all included some sort of personal story and application. They made people laugh at least fifteen times. They referred to the university as the finest university in the nation or world, and last but not least they all greeted the people in attendance. I’ll begin by doing so now.
President Holst, thank you for coming. Faculty members and staff, salutations to you all. Distinguished guests, we are happy to have you. Family members and friends, we could not be here without you. Finally, ladies and gentlemen of the class of 2009, welcome to your commencement day here at Concordia University, Saint Paul, this, the finest university in the galaxy, nay, universe. Really, it’s right up there with South Harlem Institute of Technology, the School of Hard Knocks, and Harvard. Check and check!
Graduates, we are not here to watch as our siblings, our parents, friends, or other family walk across this stage. We are here because today is our graduation day. I am going to go off on a tangent for a little bit. Over the past umpteen years, I have seen my fair share of graduations and ceremonies. In fact, I remember getting dragged along to my older brothers’ and sisters’ graduations, all 8,000 of them—at least it seems like there were that many now. Seriously, I have more family members than friends. I remember sitting here in these very seats, intently listening to the president and other distinguished guests speak, again saying welcome and thank you for coming. Each year, I got a little bit better at staying awake throughout the entire ceremony. Every time I would come up with something new to keep myself awake, daydreams, pinching my arms, or pulling leg hair; I was a very creative individual. I am proud to say that I have been awake for the entirety of this ceremony. I would like to personally thank my classmates and colleagues sitting around me for slapping me every time I even thought about dozing off. Personal story, check—and now, application!
Graduates, don’t sleep through life. If you need a close friend or colleague to keep you awake, ask. Don’t get bored with life. In the words of one of my mentors, the Australian film director, screen writer, and producer Baz Luhrman, “Do one thing every day that scares you.” Keep yourself on your toes. Stay occupied but leave room for relaxation; embrace your hobbies. Don’t get stuck in a job you hate. I am sure many of you have seen the “Did You Know?” film on YouTube. The film montages hundreds of statistics together, laying down the ground work to tell viewers that we are approaching a crossroad. The way we live is about to change dramatically. We are living in exponential times. It’s a good thing that we are exponential people.
We are at a crossing point here, now. Each of us is graduating; we are preparing to leave this place we have called home for the past few years. It’s time to move on and flourish. But let’s not leave this place for good. Let us walk away with happy memories. We have been fortunate enough to see more change in our time here than most alumni see at their alma mater in a lifetime. We have seen the destruction of Centennial, Minnesota, and Walther. Ladies, it might not mean a lot to you, but gentlemen, we had some good times there. We have seen the building and completion of the new Residence Life Center. We now see the beginnings of our very own stadium. We have seen enough offices and departments move to last any business a lifetime. Let us remember these things, the flooding of the knoll, Ultimate Frisbee beginning at ten o’clock at night, and two back-to-back Volleyball National Championship teams, with one of those championship games held where you are sitting now. I encourage all of you to walk out of this place with flashes of the old times flickering through your brains. Reflection, check!
Honorees, in the words of Michael Scott, only slightly altered, “They have no idea how high [we] can fly.” Right now you are surrounded by future politicians, film critics, producers, directors, actors, actresses, church workers, artists, the teachers of tomorrow, musicians, people who will change the world. We are all held together right here and now, by a common bond of unity. We are one graduating class.
In one of his speeches this year, President Barack Obama said, “Generations of Americans have connected their stories to the larger American story through service and helped move our country forward. We need that service now.” He is right. America needs selfless acts of service.
Hebrews 10:23–25 reads, “Let us hold unswervingly to the hope we profess, for he who promised is faithful. And let us consider how we may spur one another on toward love and good deeds. Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another—and all the more as you see the Day approaching.” Let us not leave this place as enemies but rather as friends and companions. Let us come back next fall for our first reunion, the Zero Class Reunion hosted by the wonderful and amazing workers in the alumni department. Let us go and make disciples of all nations, guided by His Word. Let us spread God’s peace, joy, and love through service to others. Congratulations, graduates! I hope to see you next homecoming. Encouragement, check!
Selecting a Topic
Wonderlane – Fork in the road, decision tree – CC BY 2.0.
One of the most common stumbling blocks for novice public speakers is selecting their first speech topic. Generally, your public speaking instructor will provide you with some fairly specific parameters to make this a little easier. You may be assigned to tell about an event that has shaped your life or to demonstrate how to do something. Whatever your parameters, at some point you as the speaker will need to settle on a specific topic. In this section, we’re going to look at some common constraints of public speaking, picking a broad topic area, and narrowing your topic.
Common Constraints of Public Speaking
When we use the word “constraint” with regard to public speaking, we are referring to any limitation or restriction you may have as a speaker. Whether in a classroom situation or the boardroom, speakers are typically given specific instructions that they must follow. These instructions constrain the speaker and limit what the speaker can say. For example, in the professional world of public speaking, speakers are often hired to speak about a specific topic (e.g. time management, customer satisfaction, or entrepreneurship). In the workplace, a supervisor may assign a subordinate to present certain information in a meeting. In these kinds of situations, when a speaker is hired or assigned to talk about a specific topic, they cannot decide to talk about something else.
Furthermore, the speaker may have been asked to speak for an hour, only to show up and find out that the event is running behind schedule, so the speech must now be made in only thirty minutes. Having prepared sixty minutes of material, the speaker now has to determine what stays in the speech and what must go. In both of these instances, the speaker is constrained as to what they can say during a speech. Typically, we refer to four primary constraints: purpose, audience, context, and time frame.
Purpose
The first major constraint someone can have involves the general purpose of the speech. As mentioned earlier, there are three general purposes: to inform, to persuade, and to entertain. If you’ve been told that you will be delivering an informative speech, you are automatically constrained from delivering a speech with the purpose of persuading or entertaining. In most public speaking classes, this is the first constraint students will come in contact with because generally, teachers will tell you the exact purpose of each speech in the class.
Audience
The second major constraint that you need to consider as a speaker is the type of audience you will have. As discussed in the chapter on audience analysis, different audiences have different political, religious, and ideological leanings. As such, choosing a speech topic for an audience that has a specific mindset can be very tricky. Unfortunately, determining what topics may or may not be appropriate for a given audience is based on generalizations about specific audiences. For example, maybe you’re going to give a speech at a local meeting of Democratic leaders. You may think that all Democrats are liberal or progressive, but there are many conservative Democrats as well. If you assume that all Democrats are liberal or progressive, you may end up offending your audience by making such a generalization without knowing better. The best way to prevent yourself from picking a topic that is inappropriate for a specific audience is to know your audience, which is why we recommend conducting an audience analysis.
Context
The third major constraint relates to the context. For speaking purposes, the context of a speech is the set of circumstances surrounding a particular speech. There are countless different contexts in which we can find ourselves speaking: a classroom in college, a religious congregation, a corporate boardroom, a retirement village, or a political convention. In each of these different contexts, the expectations for a speaker are going to be unique and different. The topics that may be appropriate in front of a religious group may not be appropriate in the corporate boardroom. Topics appropriate for the corporate boardroom may not be appropriate at a political convention.
Time Frame
The last, but by no means least important, major constraint that you will face is the time frame of your speech. In speeches that are under ten minutes in length, you must narrowly focus a topic on one major idea. For example, in a ten-minute speech, you could not realistically hope to discuss the entire topic of the US Social Security program. There are countless books, research articles, websites, and other forms of media on the topic of Social Security, so trying to crystallize all that information into ten minutes is just not realistic.
Instead, narrow your topic to something that is more realistically manageable within your allotted time. You might choose to inform your audience about Social Security disability benefits, using one individual disabled person as an example. Or perhaps you could speak about the career of Robert J. Myers, one of the original architects of Social Security1. By focusing on information that can be covered within your time frame, you are more likely to accomplish your goal at the end of the speech.
Selecting a Broad Subject Area
Once you know what the basic constraints are for your speech, you can then start thinking about picking a topic. The first aspect to consider is what subject area you are interested in examining. A subject area is a broad area of knowledge. Art, business, history, physical sciences, social sciences, humanities, and education are all examples of subject areas. When selecting a topic, start by casting a broad net because it will help you limit and weed out topics quickly.
Furthermore, each of these broad subject areas has a range of subject areas beneath it. For example, if we take the subject area “art,” we can break it down further into broad categories like art history, art galleries, and how to create art. We can further break down these broad areas into even narrower subject areas (e.g., art history includes prehistoric art, Egyptian art, Grecian art, Roman art, Middle Eastern art, medieval art, Asian art, Renaissance art, modern art). As you can see, topic selection is a narrowing process.
Narrowing Your Topic
Narrowing your topic to something manageable for the constraints of your speech is something that takes time, patience, and experience. One of the biggest mistakes that new public speakers make is not narrowing their topics sufficiently given the constraints. In the previous section, we started demonstrating how the narrowing process works, but even in those examples, we narrowed subject areas down to fairly broad areas of knowledge.
Think of narrowing as a funnel. At the top of the funnel are the broad subject areas, and your goal is to narrow your topic further and further down until just one topic can come out the other end of the funnel. The more focused your topic is, the easier your speech is to research, write, and deliver. So let’s take one of the broad areas from the art subject area and keep narrowing it down to a manageable speech topic. For this example, let’s say that your general purpose is to inform, you are delivering the speech in class to your peers, and you have five to seven minutes. Now that we have the basic constraints, let’s start narrowing our topic. The broad area we are going to narrow in this example is Middle Eastern art. When examining the category of Middle Eastern art, the first thing you’ll find is that Middle Eastern art is generally grouped into four distinct categories: Anatolian, Arabian, Mesopotamian, and Syro-Palestinian. Again, if you’re like us, until we started doing some research on the topic, we had no idea that the historic art of the Middle East was grouped into these specific categories. We’ll select Anatolian art or the art of what is now modern Turkey.
You may think that your topic is now sufficiently narrow, but even within the topic of Anatolian art, there are smaller categories: pre-Hittite, Hittite, Urartu, and Phrygian periods of art. So let’s narrow our topic again to the Phrygian period of art (1200–700 BCE). Although we have now selected a specific period of art history in Anatolia, we are still looking at a five-hundred-year period in which a great deal of art was created. One famous Phrygian king was King Midas, who according to myth was given the ears of a donkey and the power of a golden touch by the Greek gods. As such, there is an interesting array of art from the period of Midas and its Greek counterparts representing Midas. At this point, we could create a topic about how Phrygian and Grecian art differed in their portrayals of King Midas. We now have a topic that is unique, interesting, and definitely manageable in five to seven minutes. You may be wondering how we narrowed the topic down; we just started doing a little research using the Metropolitan Museum of Art’s website (http://www.metmuseum.org).
Overall, when narrowing down your topic, you should start by asking yourself four basic questions based on the constraints discussed earlier in this section:
- Does the topic match my intended general purpose?
- Is the topic appropriate for my audience?
- Is the topic appropriate for the given speaking context?
- Can I reasonably hope to inform or persuade my audience in the time frame I have for the speech?
Specific Purposes
Andrew Sutherland – Roma Street Steps – CC BY-SA 2.0.
Once you have chosen your general purpose and your topic, it’s time to take your speech to the next phase and develop your specific purpose. A specific purpose starts with one of the three general purposes and then specifies the actual topic you have chosen and the basic objective you hope to accomplish with your speech. The specific purpose answers the who, what, when, where, and why questions for your speech.
Getting Specific
When attempting to get at the core of your speech (the specific purpose), you need to know a few basic things about your speech. First, you need to have a general purpose. Once you know whether your goal is to inform, persuade, or entertain, picking an appropriate topic is easier. Obviously, depending on the general purpose, you will have a range of different types of topics. For example, let’s say you want to give a speech about hygiene. You could still write a speech about hygiene no matter what your general purpose is, but the specific purpose would vary depending on whether the general purpose is to inform (discussing hygiene practices around the globe), to persuade (telling people why they need to adopt a specific hygiene practice), or to entertain (explaining some of the strange and unique hygiene practices that people have used historically). Notice that in each of these cases, the general purpose alters the topic, but all three are still fundamentally about hygiene.
Now, when discussing specific purposes, we are concerned with who, what, when, where, why, and how questions for your speech. Let’s examine each of these separately. First, you want to know who is going to be in your audience. Different audiences, as discussed in the chapter on audience analysis, have differing desires, backgrounds, and needs. Keeping your audience first and foremost in your thoughts when choosing a specific purpose will increase the likelihood that your audience will find your speech meaningful.
Second is the “what” question or the basic description of your topic. When picking an effective topic, you need to make sure that the topic is appropriate for a variety of constraints or limitations within a speaking context.
Third, you need to consider when your speech will be given. Different speeches may be better at different times of the day. For example, explaining the importance of eating breakfast and providing people with cereal bars may be a great topic at 9:00 a.m. but may not have the same impact if you’re giving it at 4:00 p.m.
Fourth, you need to consider where your speech will be delivered. Are you giving a speech in front of a classroom? A church? An executive meeting? Depending on the location of your speech, different topics may or may not be appropriate.
The last question you need to answer within your speech is why. Why does your audience need to hear your speech? If your audience doesn’t care about your specific purpose, they are less likely to pay attention to your speech. If it’s a topic that’s a little more off-the-wall, you’ll really need to think about why they should care.
Once you’ve determined the who, what, when, where, and why aspects of your topic, it’s time to start creating your actual specific purpose. First, a specific purpose, in its written form, should be a short, declarative sentence that emphasizes the main topic of your speech. Let’s look at an example:
| Topic | The military |
| Narrower Topic | The military’s use of embedded journalists |
| Narrowed Topic | The death of British reporter Rupert Hamer in 2010 in a roadside bombing in Nawa, Afghanistan, along with five US Marines |
In this example, we’ve quickly narrowed a topic from a more general topic to a more specific topic. Let’s now look at that topic in terms of a general purpose and specific purpose:
| General Purpose | To inform |
| Specific Purpose | To inform my audience about the danger of embedded journalism by focusing on the death of British reporter Rupert Hamer |
| General Purpose | To persuade |
| Specific Purpose | To persuade a group of journalism students to avoid jobs as embedded journalists by using the death of British reporter Rupert Hamer as an example of what can happen |
For the purpose of this example, we used the same general topic area and demonstrated how you could easily turn the topic into either an informative speech or a persuasive speech. In the first example, the speaker is going to talk about the danger embedded journalists face. In this case, the speaker isn’t attempting to alter people’s ideas about embedded journalists, just make them more aware of the dangers. In the second case, the specific purpose is to persuade a group of journalism students (the audience) to avoid jobs as embedded journalists.
Your Specific Statement of Purpose
To form a clear and succinct statement of the specific purpose of your speech, start by naming your general purpose (to inform, to persuade, or to entertain). Follow this with a capsule description of your audience (my peers in class, a group of kindergarten teachers, etc.). Then complete your statement of purpose with a prepositional phrase (a phrase using “to,” “about,” “by,” or another preposition) that summarizes your topic. As an example, “My specific purpose is to persuade the students in my residence hall to protest the proposed housing cost increase” is a specific statement of purpose, while “My speech will be about why we should protest the proposed housing cost increase” is not.
Specific purposes should be statements, not questions. If you find yourself starting to phrase your specific purpose as a question, ask yourself how you can reword it as a statement. Table 6 “My Specific Purpose Is…” provides several more examples of good specific purpose statements.
Table 6 My Specific Purpose Is…
| General Purpose | Audience | Topic |
|---|---|---|
| To inform | my audience | about the usefulness of scrapbooking to save a family’s memories. |
| To persuade | a group of kindergarten teachers | to adopt a new disciplinary method for their classrooms. |
| To entertain | a group of executives | by describing the lighter side of life in “cubicle-ville.” |
| To inform | community members | about the newly proposed swimming pool plans that have been adopted. |
| To persuade | my peers in class | to vote for me for class president. |
| To entertain | the guests attending my mother’s birthday party | by telling a humorous story followed by a toast. |
Basic Tips for Creating Specific Purposes
Now that we’ve examined what specific purposes are, we are going to focus on a series of tips to help you write specific purposes that are appropriate for a range of speeches.
Audience, Audience, Audience
First and foremost, you always need to think about your intended audience when choosing your specific purpose. In the previous section, we talked about a speech where a speaker is attempting to persuade a group of journalism students to not take jobs as embedded journalists. Would the same speech be successful, or even appropriate, if given in your public speaking class? Probably not. As a speaker, you may think your topic is great, but you always need to make sure you think about your audience when selecting your specific purpose. For this reason, when writing your specific purpose, start off your sentence by actually listing the name of your audience: a group of journalism students, the people in my congregation, my peers in class, and so on. When you place your audience first, you’re a lot more likely to have a successful speech.
Matching the Rhetorical Situation
After your audience, the second most important consideration about your specific purpose pertains to the rhetorical situation of your speech. The rhetorical situation is the set of circumstances surrounding your speech (e.g., speaker, audience, text, and context). When thinking about your specific purpose, you want to ensure that all these components go together. You want to make sure that you are the appropriate speaker for a topic, the topic is appropriate for your audience, the text of your speech is appropriate, and the speech is appropriate for the context. For example, speeches that you give in a classroom may not be appropriate in a religious context and vice versa.
Make It Clear
The specific purpose statement for any speech should be direct and not too broad, general, or vague. Consider the lack of clarity in the following specific purpose: “To persuade the students in my class to drink more.” Obviously, we have no idea what the speaker wants the audience to drink: water, milk, orange juice? Alcoholic beverages? Furthermore, we have no way to quantify or make sense of the word “more.” “More” assumes that the students are already drinking a certain amount, and the speaker wants them to increase their intake. If you want to persuade your listeners to drink eight 8-ounce glasses of water per day, you need to say so clearly in your specific purpose.
Another way in which purpose statements are sometimes unclear comes from the use of colloquial language. While we often use colloquialisms in everyday life, they are often understood only by a limited number of people. It may sound like fun to have a specific purpose like, “To persuade my audience to get jiggy,” but if you state this as your purpose, many people probably won’t know what you’re talking about at all.
Don’t Double Up
You cannot hope to solve the entire world’s problems in one speech, so don’t even try. At the same time, you also want to make sure that you stick to one specific purpose. Chances are it will be challenging enough to inform your audience about one topic or persuade them to change one behavior or opinion. Don’t put extra stress on yourself by adding topics. If you find yourself using the word “and” in your specific topic statement, you’re probably doubling up on topics.
Can I Really Do This Speech in Five to Seven Minutes?
When choosing your specific purpose, it’s important to determine whether it can be realistically covered in the amount of time you have. Time limits are among the most common constraints for students in a public speaking course. Speeches early in the term have shorter time limits, and speeches later in the term have longer time limits. To determine whether you think you can accomplish your speech’s purpose in the time slot, ask yourself how long it would take to make you an informed person on your chosen topic or to persuade you to change your behavior or attitudes.
If you cannot reasonably see yourself becoming informed or persuaded during the allotted amount of time, chances are you aren’t going to inform or persuade your audience either. The solution, of course, is to make your topic narrower so that you can fully cover a limited aspect of it.
A specific purpose starts with one of the three general purposes and then specifies the actual topic you have chosen and the basic objective you hope to accomplish with your speech.
The rhetorical situation is the set of circumstances surrounding your speech (e.g., speaker, audience, text, and context). When thinking about your specific purpose, you want to ensure that all these components go together.
Crafting and Understanding Thesis Statements for Speeches
You might be familiar with a thesis statement in writing an essay. Thesis statements are similar in speeches, but slightly different because they are only heard and not read. To help us understand thesis statements, we will first explore their basic functions and then discuss how to write a thesis statement.
Basic Functions of a Thesis Statement
A thesis statement helps your audience by letting them know what you are going to talk about “in a nutshell.” With a good thesis statement, you will fulfill four basic functions: you express your specific purpose, provide a way to organize your main points, make your research more effective, and enhance your delivery.
Express Your Specific Purpose
To orient your audience, you need to be as clear as possible about your meaning. A strong thesis will prepare your audience effectively for the points that will follow. Here are two examples:
- “Today, I want to discuss academic cheating.” (weak example)
- “Today, I will clarify what plagiarism is and give examples of its different types so that you can see how it leads to a loss of creative learning interaction.” (strong example)
The weak statement will probably give the impression that you have no clear position on your topic because you haven’t said what that position is. Additionally, the term “academic cheating” can refer to many behaviors: acquiring test questions ahead of time, copying answers, changing grades, or allowing others to do your coursework. Therefore, the specific topic of the speech is still not clear to the audience. The strong statement not only specifies plagiarism but also states your specific concern (loss of creative learning interaction).
Provide a Way to Organize Your Main Points
A thesis statement should appear, almost verbatim, toward the end of the introduction to a speech. A thesis statement helps the audience get ready to listen to the arrangement of points that follow. Many speakers say that if they can create a strong thesis sentence, the rest of the speech tends to develop with relative ease. On the other hand, when the thesis statement is not very clear, creating a speech is an uphill battle. When your thesis statement is sufficiently clear and decisive, you will know where you stand on your topic and where you intend to go with your speech. Having a clear thesis statement is especially important if you know a great deal about your topic or you have strong feelings about it. If this is the case for you, you need to know exactly what you are planning on talking about in order to fit within specified time limitations. Knowing where you are and where you are going is the entire point in establishing a thesis statement; it makes your speech much easier to prepare and to present.
Let’s say you have a reasonably strong thesis statement, and that you’ve already brainstormed a list of information that you know about the topic. Chances are your list is too long and has no focus. Using your thesis statement, you can select only the information that (1) is directly related to the thesis and (2) can be arranged in a sequence that will make sense to the audience and will support the thesis. In essence, a strong thesis statement helps you keep useful information and weed out less helpful information.
Make Your Research More Effective
If you begin your research with only a general topic in mind, you run the risk of spending hours reading mountains of excellent literature about your topic. However, mountains of research does not always make coherent speeches.
You may have little or no idea of how to tie your research together, or even whether you should tie it together. If, on the other hand, you conduct your research with a clear thesis statement in mind, you will be better able to zero in only on material that directly relates to your chosen thesis statement. Let’s look at an example that illustrates this point:
Many traffic accidents involve drivers older than fifty-five. While this statement may be true, you could find industrial, medical, insurance literature that can drone on ad infinitum about the details of all such accidents in just one year. Instead, focusing your thesis statement will help you narrow the scope of information you will be searching for while gathering information.
Here’s an example of a more focused thesis statement:
Three factors contribute to most accidents involving drivers over fifty-five years of age: failing eyesight, slower reflexes, and rapidly changing traffic conditions.
This framing is somewhat better. This thesis statement at least provides three possible main points and some keywords for your electronic catalog search. However, if you want your audience to understand the context of older people at the wheel, consider something like:
Mature drivers over fifty-five years of age must cope with more challenging driving conditions than existed only one generation ago: more traffic moving at higher speeds, the increased imperative for quick driving decisions, and rapidly changing ramp and cloverleaf systems. Because of these challenges, I want my audience to believe that drivers over the age of sixty-five should be required to pass a driving test every five years.
This framing of the thesis provides some interesting choices. First, several terms need to be defined, and these definitions might function surprisingly well in setting the tone of the speech. Your definitions of words like “generation,” “quick driving decisions,” and “cloverleaf systems” could jolt your audience out of assumptions they have taken for granted as truth.
Second, the framing of the thesis provides you with a way to describe the specific changes as they have occurred between, say, 1970 and 2010. How much, and in what ways, have the volume and speed of traffic changed? Why are quick decisions more critical now? What is a “cloverleaf,” and how does any driver deal cognitively with exiting in the direction seemingly opposite to the desired one? Questions like this, suggested by your own thesis statement, can lead to a robust and memorable speech.
Enhance Your Delivery
When your thesis is not clear to you, your listeners will be even more clueless than you are. However, if you have a good clear thesis statement, your speech becomes clear to your listeners. When you stand in front of your audience presenting your introduction, you can vocally emphasize the essence of your speech, expressed as your thesis statement.
Many speakers pause for a half second, lower their vocal pitch slightly, slow down a little, and deliberately present the thesis statement, the one sentence that encapsulates its purpose. When this is done effectively, the purpose, intent, or main idea of a speech is driven home for an audience.
How to Write a Thesis Statement
Now that we’ve looked at why a thesis statement is crucial in a speech, let’s switch gears and talk about how we go about writing a solid thesis statement.
Choose Your Topic
The first step in writing a good thesis statement is finding your topic. Once you have a general topic, you are ready to go to the second step of creating a thesis statement.
Narrow Your Topic
One of the hardest parts of writing a thesis statement is narrowing a speech from a broad topic to one that can be easily covered during a five- to ten-minute speech. While five to ten minutes may sound like a long time to new public speakers, the time flies by very quickly when you are speaking. You can run out of time if your topic is too broad. To decide if your topic is narrow enough for a specific time frame, ask yourself three questions:
First, is your thesis statement narrow or is it a broad overgeneralization of a topic? Overgeneralization occurs when we classify everyone in a specific group as having a specific characteristic. For example, a speaker’s thesis statement that “the elderly are bad drivers” is an overgeneralization of all elderly drivers. Make sure that your thesis statement is nuanced enough to accurately represent what you can support in your speech.
The second question to ask yourself when narrowing a topic is whether your speech’s topic is one clear topic or multiple topics. A strong thesis statement consists of only a single topic. The following is an example of a thesis statement that contains too many topics: “Medical marijuana and prostitution should be legalized in the United States.” Not only are both broad, but you also have two completely unrelated topics thrown into a single thesis statement. Instead of a thesis statement that has multiple topics, limit yourself to only one topic. Here’s an example of a thesis statement examining only one topic: “Today we’re going to examine the legalization and regulation of prostitution in the state of Nevada.” In this case, we’re focusing our topic on how one state has handled the legalization and regulation of prostitution.
The last question a speaker should ask when making sure a topic is sufficiently narrow is whether the topic has direction. If your basic topic is too broad, you will never have a solid thesis statement or a coherent speech. For example, if you start off with the topic “Barack Obama is a role model for everyone,” what do you mean by this statement? Do you think President Obama is a role model because of his dedication to civic service? Do you think he’s a role model because he’s a good basketball player? Do you think he’s a good role model because he’s an excellent public speaker? When your topic is too broad, almost anything can become part of the topic. This broadness ultimately leads to a lack of direction and coherence within the speech itself. To make a cleaner topic, a speaker needs to narrow their topic to one specific area. For example, you may want to examine why President Obama is a good speaker.
Put Your Topic into a Sentence
Once you’ve narrowed your topic to something that is reasonably manageable given the constraints placed on your speech, you can then formalize that topic as a complete sentence. For example, you could turn the topic of President Obama’s public speaking skills into the following sentence: “Because of his unique sense of lyricism and his well-developed presentational skills, President Barack Obama is a modern symbol of the power of public speaking.” Once you have a clear topic sentence, you can start tweaking the thesis statement to help set up the purpose of your speech. Your thesis statement should be a clear, declarative statement that sets up your speech.
Use the Thesis Checklist
Once you have written the first draft of your thesis statement, you’re probably going to end up revising your thesis statement a number of times before delivering your actual speech. A thesis statement is something that is constantly tweaked until the speech is given. As your speech develops, often your thesis will need to be rewritten to whatever direction the speech itself has taken. We often start with a speech going in one direction and find out through our research that we should have gone in a different direction. When you think you finally have a thesis statement that is good to go for your speech, take a second and make sure it adheres to the criteria shown below.
Thesis Checklist
Instructions: For each of the following questions, check either “yes” or “no.” Yes No
- Does your thesis clearly reflect the topic of your speech?
- Can you adequately cover the topic indicated in your thesis within the time you have for your speech?
- Is your thesis statement simple?
- Is your thesis statement direct?
- Does your thesis statement gain an audience’s interest?
- Is your thesis statement easy to understand?
- Does your thesis statement introduce a clear argument?
- Does your thesis statement clearly indicate what your audience should know, do, think, or feel?
Scoring: For a strong thesis statement, all your answers should have been “yes.”
Conclusion
After reading this chapter, we hope that you now have a better understanding not only of the purpose of your speech but also of how to find a fascinating topic for yourself and your audience. We started this chapter citing lyrics from the Avenue Q song “Purpose.” While the character is trying to find his purpose in life, we hope this chapter has helped you identify your general purpose, choose a topic that will interest you and your audience, and use these to develop a specific purpose statement for your speech.
