• Use appropriate gestures to help make a point. Use hand movements, facial expressions, and body language. Do not stand frozen to one spot; move around, if appropriate. In a large auditorium, it is better to have a portable microphone than to be locked to a lectern with a fixed microphone. If you do walk around, whether in a small meeting room or an auditorium, always face the audience when you speak; never speak with your back to the audience, such as facing the projector screen.
