Re:Creating artificial phonemes (Score 0)

This is kind of how the formant/parametric TTS engines work; they use a simulation of the vocal tract to generate sounds on the fly. This does have some advantages, but for whatever reason (I don't know enough to say), the concatenative TTS engines sound much more "natural" right now. And there are many that are commercially available: Rhetorical Systems, Nuance, SpeechWorks (which was developed from AT&T IIRC). If you are interested in an open source TTS engine, check out Festival from the University of Edinburgh, or Flite (Festival-lite) from Carnegie-Mellon. Flite is a Festival relative that is optimized for PDAs and multi-channel servers.

Someday I think their might be a resurgence in the parameteric TTS engines, but I guess the techniques need to advance. I think of them as being more "pure".
