The first is a 1999 presentation from MIT Professor Patrick Winston. In the presentation, delivered every year during MIT’s Independent Activities Period, Winston provides a set of speaking heuristics that he has developed and refined over his career. The video is a bit long at 50-minutes, but gives some really simple and useful techniques.
Following the video is Ian McKenzie's brief description of the four types of speeches most people will typically encounter.

Ian McKenzie at Ian’s Messy Desk details 4 Basic Types of Speeches:
a speech will generally fall into one of four basic types:
- Informative – This speech serves to provide interesting and useful information to your audience.
- Demonstrative Speeches – This has many similarities with an informative speech. A demonstrative speech also teaches you something. The main difference lies in including a demonstration of how to do the thing you’re teaching.
- Persuasive – A persuasive speech works to convince people to change in some way: they think, the way they do something, or to start doing something that they are not currently doing.
- Entertaining — The after-dinner speech is a typical example of an entertaining speech. The speaker provides pleasure and enjoyment that make the audience laugh or identify with anecdotal information.
