What are props and how are they used in a speech?

When giving a speech, the most important thing to focus on is the value of the words that you are using. However, this is not the only element that is relevant. A speaker should also focus on other factors, such as his body language and props.

Props are devices that can be used to support your speech and extend the meaning of the words you are conveying. These are items that the speaker employs to draw the audience in. It is important to remember that props should not be the focus of your speech. Instead, they should simply offer support for your ideas. Moreover, props should be employed only when they bring value to a presentation, as they can distract the audience.
