Nowadays, the automatic processing for 3D facial animation has been studied intensively and a variety of techniques has been proposed so far. For instance, some facial animation softwares are based on audio capture [5] and others are based on motion capture [7, 6]. Independently of the approach used, it is fundamental that the capture solution assure lip movements synchronization with audio. Surely, this issue represents the state-of-art and many efforts have been made to solve it. Lip synchronization is the most complex process in the production of an animation and, commonly, it takes a long time.
