A demonstrative speech, which can also be referred to as a demonstration speech, explains how listeners can do something by giving them specific instructions and details. It is a form of expository speaking.
In a demonstration speech, the presenter must give background information on the subject and set the scene for the audience. After that, they can move forward with the demonstration, which can be as simple as teaching people how to put on a swim cap or as complex as teaching people how to make deviled eggs. Most of the time, the speeches are limited to around 10 minutes and the speaker may use one person to assist with the demonstration.
