I was a shy little kid, and getting up in front of people and making them laugh and being able to carry on a dialogue rather than a monologue was something that was pretty interesting to me because you could set yourself up - you could ask a question and then answer it.
The only way a ventriloquist speaks differently is that he forgoes using his or her lips, and learns to reproduce sounds using the tongue, upper palate, and teeth only. Those 'difficult' letters are B, F, M, P, V, W, and Y.
When I was in third grade I taught myself ventriloquism... What's hard is to learn to be an entertainer and make people laugh. I was a few years out of college before I felt I had enough material. Then in 1988 I moved to L.A. and started to do some shows at comedy clubs.
But the mechanics of learning to 'throw your voice' are pretty simple. Anyone with a tongue, an upper palate, teeth, and a normal speaking voice can learn ventriloquism.
I'm a pretty good ventriloquist, but it's the entertainment value and the laughs that keep people sitting there and wanting more.
The magic in performing as an entertaining ventriloquist happens when the characters come to life and the interaction between the separate personalities on stage becomes 'real.' Then don't forget that the act has to be funny, and to me, being funny and entertaining any given audience is more important than anything.
What I do for a living is whimsical and fun and ridiculous. I'm supposed to make people laugh. We all have that child in us. For many people, that child gets pushed into a corner. But if you want to be creative, that little kid can never go away.
As humans we like to laugh at our fears, we like to whistle in the dark.
