What are the types of speech genres?

There are five main types of speech genres: descriptive, narrative, expository, persuasive, and argumentative. Descriptive speech aims to create a vivid picture in the listener's mind, while narrative speech tells a story. Expository speech explains a subject, persuasive speech aims to convince the audience to take a specific action, and argumentative speech presents a debatable topic with evidence to support a particular viewpoint.
