There two main types of extemporaneous speaking topics are informative and persuasive speeches. An example of an informative speaking prompt is "What is the state of the Ebola virus epidemic?" A persuasive question is "Should the United States raise its minimum wage?"
The goal of extemporaneous speaking is to briefly inform or persuade the audience on a question given to the speaker to answer. Most questions come from current political, social, national and world events. In order to give an extemporaneous speech, a speaker must be familiar with the topics. In most cases, he might have 30 minutes or less time to prepare. These presentations follow the general outline of a speech, which includes a introduction, body and closing remarks.
