Here are some tips for effective speaking in front of others, but not with your voice, but rather with what you are conveying with your body:
Use your gestures.
Begin with a neutral position of standing tall with your hands at your sides. When you think about hand placement it will start to feel unnatural and strange, but just let them hang at your sides to begin with. Keep yourself open to the audience, don’t turn your back to them to view a slide. Keep your shoulders at a straight or very narrow angle to the back wall of the room. Make sure that the gestures you use are sparing, and defined. Think of how many presidents comedians can imitate just using the hand gestures that the president favored. That definition and decisive gesture can drive home the impact of your words. If you are a natural “hand-talker” (someone who illustrates their conversation with many hand gestures) don’t try to fight your nature and keep your hands still, because you will look unnatural, but do try to pare it down to the core gestures you use to make your point.
Manage your stress.
No one likes speaking to a crowd, but those that do it professional have learned to turn it into energy. To funnel the nervousness and loop it around into exhilaration. Energy is a good thing and keeps your presentation alive and engaging, but letting stress get the best of you will lead to vocal tics and other nonverbal behaviors that might undermine your words. Sports players are often known for jumping a little in place before going out to field, stadium, or court, and turning nervousness into excitement. Clench and release your fists to relieve tension, bounce a little on your toes, breathe deeply from your belly, look at a wall straight ahead of you. Exhale slowly and feel all of your muscles relax in a wave. Concentrate on your toes, then your feet, then your ankles, and relax your muscles with your mind all the way up your body. Think about being excited rather than nervous.
Use your space.
Ditch the podium, forget the chair. Walk around the stage and fill it with your presence. Don’t pace around in circles, but do use what you have to keep the energy going and to keep eyes following you. Humans are drawn to movement and are more likely to be engaged with you if you use the space you have. But when you key to a key point, stop and face the audience, stand still and possessively, and really drive your point home.
Power poses.
The most viewed TED Talk of all time is Amy Cuddy’s TED Talk about body language. It talked about how body language doesn’t just shape how other people perceive you, it can also shape you you perceive yourself. Puting energy and dynamic movement into posing and standing in a way that can convey power doesn’t just make others look at you differently, it can make you actually feel more powerful.
