hi,all I want to do the lipsync for my cg animation. I think I have to know the Phoneme/Viseme in a given time. My questions are: 1.How to get the Phoneme/Viseme information in audio file (wav/ogg/...)? 2.Can i get the Phoneme/Viseme in Ogg file if any? 3.Or, Is there any free software available which can generate the Phoneme/Viseme information from audio file? Thanks in advance.

Toonboom Studio is a flash animation program that generates phoneme keyframes--it's pretty rough, but it's a decent guideline.

These guys have some software dedicated for this sort of thing. I'm not sure about licensing and such, but you could speak with them.
