'Speech is after all only a system of gestures'
- Robin George Collingwood (1889-1943), British philosopher. Principles of Art, chapter 11, Oxford University Press (1938).
I want you to have a real, long hard look and observe people when they speak. Notice anything? It doesn't matter whether it's a teacher talking in front of a class, a friend talking on the phone, or a newsreader reading aloud the evening news, what you should have noticed is that all these people move - their hands, heads, eyes, and their voice also change depending on what and who they are speaking about and to.
Firstly, when people speak to one another, they look at each other. Secondly, people move and use gestures. Thirdly, people will use and change their voice to make others listen.
When you get up to speak in front of others, you will ultimately be the focus of your audience's attention. As a speaker it is your responsibility to deliver your message and enhance it by paying attention to these three presentation points: eye contact, gestures and voice projection.
