Vocal synthesis has always been notoriously hard to achieve, however it is getting better and better.
The Pink Trombone created by Neil Thapen attempts to recreate the human voice using a web application.
Sound is created in the glottis in the bottom left of the screen, then filtered by the shape of the vocal tract. The voice box controls the intensity and the pitch of the initial sound.
Then to talk:
- Move the body of the tongue to shape vowels
- Touch the oral cavity to narrow is for fricative consonants
- Touch the oral cavity to close it, for stop consonants
- Touch the naval cavity to open the velum and let sound flow through the nose.
Try this out on a multi-touch device, we guarantee you'll be stuck for at least an hour ;-)
