Overview
This lecture explains the three main types of speeches—informative, persuasive, and commemorative/entertaining—along with examples and the occasions for each.
General Purposes of Public Speaking
- Public speeches fall into three general purposes: to inform, to persuade, or to commemorate/entertain.
- The purpose of a speech is usually determined by the occasion.
Informative Speeches
- Informative speeches share information about people, places, objects, processes, concepts, or issues.
- These speeches involve defining, describing, or explaining a subject to the audience.
- Examples include workplace reports, classroom lessons, or job training sessions.
Persuasive Speeches
- Persuasive speeches aim to reinforce or change audience beliefs, attitudes, feelings, or values.
- They involve convincing or motivating the audience toward a particular stance or action.
- Typical occasions are sales pitches, political campaign speeches, or debates in public forums.
Commemorative and Entertaining Speeches
- Commemorative/entertaining speeches celebrate, honor, or amuse, often strengthening audience bonds.
- Examples are toasts at weddings, eulogies, commencement speeches, or award presentations.
- These speeches use humor, stories, or shared experiences to connect with listeners.
Overlap and Flexibility
- The three general purposes may overlap; a speech can inform and entertain or persuade and amuse.
- Speakers often use elements from multiple types to best engage their audience.
