HD complete characters speaking naturally

[Frank Verberne]

We're thinking of buying the HD complete character set. One very interesting features of these characters would be the facial expressions. I'm especially interested in making the characters speak more naturally (the lipflapping of vizact.speak() is far from optimal for conversational agents). Is it possible to let the HD characters speak with phonemes (see http://www.karisproductions.com/wp-c...neme-Chart.jpg)? If so, how would you extract phonemes from a wav-file (or a sound in another format), so that the HD characters gets the information which lip movements to make to speak realistically? Would you need the Microsoft Speech API for this?

Most important question: could we test this with the HD complete character that comes with Vizard4?
