Do you use Papagayo for lip syncing to .DAT file? Wellllll guesssss what! I paid a programmer to update it with voice recognition capabilities. It's currently Windows / English only and only supports mono 16bit WAV files (and there are probably some bugs), but it's free and open source, so, what do you expect! Give it a try!
