Speeches come in all shapes and sizes, and are given by speakers and are received by audiences of all backgrounds. A speech is broadly defined, and can include any type of presentation, either at school, college or work, though speeches as we mostly think of them are most important for subjects and official positions that require the support of the audience, such as academics, politics, religion, public understanding and public relations. From a 4th grade class presentation to an inaugural address, speeches are extremely important as they are the quickest and most effective way to communicate, inform, engage and persuade. This article covers the two major types of preparatory speeches.
Of all the different types of speeches, all will have information to talk about, but an informative speech is centered on the sharing of new information. These types of speeches are important to help the audience understand a new or existing subject, and to build insight through the analysis of information. There are no concealed agendas or ulterior motives, and if the subject is contentious with opposing groups, the speaker will not take a certain side and remain neutral and objective. This means the speaker will not plant their own emotions or personal experiences, or use any other techniques that incite emotional response. The evidence provided can come from anywhere as long as it is authoritative, and if it is not the speaker should make this known clearly.
Persuasive types of speeches are quite different and in some ways contrasting to informative types of speeches. The overall goal is to within appropriate means, influence the audience to have them adopt your argument of the issue. You must still adhere to the rules of reasoning and arguments, but you are also able to use things other than pure evidence to persuade the audience into believing your argument, even if your argument is not infallible. If the audience senses that you are not being honest, then your persuasive speech will not work. It is always best to be use logic and reasoning just as in an informative speech, but use mild persuasive tactics to your advantage. Employ figures of speech, study your intonation, and make sure you know how to amplify the arguments which support your cause, and diminish opposing arguments that may put your argument in jeopardy.
