Politicians use them. Television hosts use them. Why shouldn’t you?
The most direct answer is that speaking from a teleprompter is hard. If most speakers who read from a prepared script sound like they’re reading from a script, imagine how much tougher it is to read one from two small panels of glass, flanked on the speaker’s left and right sides, located feet apart from one another.
Because it’s difficult for most speakers to develop a rapport with their audiences while using a teleprompter, we typically discourage their use. In limited circumstances, though, the teleprompter can be a useful tool. (An example: a high-stakes event at which the precision of your words—which will carry to a much broader audience outside the room—matters more than the connection you forge with the live audience inside the room.)
