Abstract
A method of producing synthetic visual speech according to this invention includes receiving an input containing speech information. One or more visemes that correspond to the speech input are then identified. Next, the weights of those visemes are calculated using a coarticulation engine including viseme deformability information. Finally, a synthetic visual speech output is produced based on the visemes' weights over time (or tracks). The synthetic visual speech output is combined with a synchronized audio output corresponding to the input to produce a multimedia output containing a 3D lipsyncing animation.
