Major Types of Informative Speeches
In this guide, we focus on informative speeches about:
These categories provide an effective method of organizing and evaluating informative speeches. Although they are not absolute, these categories provide a useful starting point for work on your speech.
In general, you will use four major types of informative speeches. While you can classify informative speeches many ways, the speech you deliver will fit into one of four major categories.
Speeches about Objects
Speeches about objects focus on things existing in the world. Objects include, among other things, people, places, animals, or products.
Because you are speaking under time constraints, you cannot discuss any topic in its entirety. Instead, limit your speech to a focused discussion of some aspect of your topic.
Some example topics for speeches about objects include: the Central Intelligence Agency, tombstones, surgical lasers, Franklin Delano Roosevelt, the pituitary gland, and lemmings.
To focus these topics, you could give a speech about Franklin Delano Roosevelt and efforts to conceal how he suffered from polio while he was in office. Or, a speech about tombstones could focus on the creation and original designs of grave markers.
Speeches about Processes
Speeches about processes focus on patterns of action. One type of speech about processes, the demonstration speech, teaches people "how-to" perform a process. More frequently, however, you will use process speeches to explain a process in broader terms. This way, the audience is more likely to understand the importance or the context of the process.
A speech about how milk is pasteurized would not teach the audience how to milk cows. Rather, this speech could help audience members understand the process by making explicit connections between patterns of action (the pasteurization process) and outcomes (a safe milk supply).
Other examples of speeches about processes include: how the Internet works (not "how to work the Internet"), how to construct a good informative speech, and how to research the job market. As with any speech, be sure to limit your discussion to information you can explain clearly and completely within time constraints.
Speeches about Events
Speeches about events focus on things that happened, are happening, or will happen. When speaking about an event, remember to relate the topic to your audience. A speech chronicling history is informative, but you should adapt the information to your audience and provide them with some way to use the information. As always, limit your focus to those aspects of an event that can be adequately discussed within the time limitations of your assignment.
Examples of speeches about events include: the 1963 Civil Rights March on Washington, Groundhog's Day, the Battle of the Bulge, the World Series, and the 2000 Presidential Elections.
Speeches about Concepts
Speeches about concepts focus on beliefs, ideas, and theories. While speeches about objects, processes, and events are fairly concrete, speeches about concepts are more abstract. Take care to be clear and understandable when creating and presenting a speech about a concept. When selecting a concept, remember you are crafting an informative speech. Often, speeches about concepts take on a persuasive tone. Focus your efforts toward providing unbiased information and refrain from making arguments. Because concepts can be vague and involved, limit your speech to aspects that can be readily explained and understood within the time limits.
Some examples of topics for concept speeches include: democracy, Taoism, principles of feminism, the philosophy of non-violent protest, and the Big Bang theory.
