Many people think that delivery is the most important part of a speech because it makes the information presented interesting and pleasing to the audience. Yet, the best delivered speech will not seem fulfilling to the audience unless there is some kind of substantiation and conviction put into the address. In fact, in-depth research can actually help delivery. Thorough research can lead to an organized, flowing, and confidently delivered speech. Research itself can also become easier as the student moves along in their studying.
Extensive research can make a speech more organized because of the way humans store knowledge.
The speech that I researched the most this year was an informative speech on oil as a cause for war throughout the twentieth century. For weeks I studied books and magazines and talked to Whitman professors about different aspects of the speech, which strengthened my overall understanding of the topic. Thus when I gave the speech I did not have to rely on notes very much. This is because the brain tends to store information in logical patterns so things are easier to remember. Another way speakers can help organizing through research is by choosing the right topic.
