Quick public speaking tip – Is your audience illiterate?

Well, are they?
Probably not.
If your words are on the screen or sheet of paper, then let the audience read for themselves. This will have enormous impact, especially if your audience is used to presenters slavishly following the test on their visuals.
You are presenting your message verbally, and visuals are just that – images or groups or words that support your message. They are not the message itself. If necessary, you may have to explain this, first, because many audiences have been trained by presenters who cover their inadequacies by using their visuals as the message.
This may just be why you will make an impact if you can present without using this method. You will be different. You will be seen as so much more confident and competent as a person.
But underneath all of that is the fact that your audience is not illiterate. Don’t annoy them by reading to them what they can read themselves.
