As you've already learned, informative speeches show, clarify, and inform. To give the audience the information they've come for, you need to learn how to focus on a topic, decide on an effective method of organization, and include sufficient details, examples, and facts. Always start with the topic.
Said the after-dinner speaker: “I feel like Roseanne's fourth husband. I know what I'm supposed to do, but I'm at a loss how to make it different.” You won't feel like Roseanne's fourth husband if you start writing an informative speech by choosing a central theme, the main idea or thesis.
As you plan your informative speech, ask yourself, “What is the one idea that I want to convey to my listeners?” That's your theme. First of all, effective themes should appeal to you as well as your audience, because your speech will be more interesting if you're interested in the topic. It will also be easier to write. In addition, effective themes …
A speech's theme is its thesis, the main idea.
Once you've settled on a theme, it's time to select a method of organization that fits with your audience, purpose, and topic.
Never forget the implied contract between speaker and audience: They must sit still and listen politely. In exchange, you must have something of value to say.
Remember that an informational speech is designed to convey the speaker's ideas to the audience. The best-written speeches concentrate on helping listeners grasp and remember the essential ideas the speaker presents. To make sure your speech conveys its purpose, select a clear method of organization. Possibilities include …
It's especially important with speeches to include clues to help your readers follow your method of organization. Possibilities include numbers (such as 1, 2, 3 or the words “first,” “second,” “third,” etc.) and transitions (“in contrast,” “on the other hand,” “however,” and so on).
In addition, keep your points to a minimum. Three or four main points are usually the most an audience can absorb at one sitting. This is exactly the same as the five-paragraph essay structure you learned in You Got Some 'Splaining to Do, Lucy: Exposition (introduction, three main points, conclusion). Also, be sure to link your points clearly and logically. This is crucial with speeches, because you're dealing with an oral medium: Unlike readers, listeners can't go back and reread a confusing passage.
Informational speeches are content-oriented—but that doesn't mean they're dull or dry. Just the opposite is true! As with all effective writing, good speeches are compelling because they include tantalizing facts, delicious details, and succulent examples.
Specific facts are the backbone of any informational speech, because that's what your listeners are going to remember. To get the facts to back up your point, read widely on your topic. Check reference books, the Internet, and experts in the field—the exact same techniques you use when you're writing an expository essay.
Never include material that's off the topic, cannot be verified, is boring, or might insult your audience.
On February 12, 1959, the 150th anniversary of Abraham Lincoln's birth, the poet Carl Sandburg delivered a speech to a special joint session of Congress.
