Abstract:
Talking computer animated characters are a common sight in video games and movies. Although doing the mouth animation by hand gives the best results it is not always feasible because of cost or time constraints. Therefore producing lip animation automatically is highly desirable. The problem can therefore be phrased as mapping from speech to lip animation or in other words as an acoustic inversion. In our work we propose a solution that takes a sequence of input frames of speech and maps it directly to an output sequence of animation frames. The key point is that there is no need for phonemes or visemes which cuts one step in the usual lip synchronization process.
