A Real-Time 3D Visual Singing Synthesis: From Appearance to Internal Articulators

A facial animation system is proposed for visual singing synthesis. With a reconstructed 3D head mesh model, both finite element method and anatomical model are used to simulate articulatory deformation corresponding to each phoneme with musical note. Based on an articulatory song corpus, articulatory movements, phonemes and musical notes are trained simultaneously to obtain the visual co-articulation model by a context-dependent Hidden Markov Model. Articulatory animations corresponding to all phonemes are concatenated by visual co-articulation model to produce the song synchronized articulatory animation. Experimental results demonstrate the system can synthesize realistic song synchronized articulatory animation for increasing the human computer interaction capability objectively and subjectively.
