What a voice can do.

I love this TED talk from Reggie Watts.  It's about 15 minutes and shows the range of voice and speech contained in a single human being.  Reggie is experimental, funny and allows himself to play with all the things carried in voice and speech - identity, age, race, nonsense, music.  


How does he do it?  My suspicion is that it's through a lot of experimentation and play.
