Resumen:
In this paper, a speech-driven MPEG-4 compliant facial animation system is proposed. The system is based on the inversion of a joint Audio-Visual Hidden Markov Model to estimate the visual information from speech data. The inversion algorithm is derived for the general case of considering full covariance matrices for the audio-visual observations. The proposed speech-driven facial animation system operates at a subphonemic level, with the advantage of being adaptable to any language. The experiments are carried out using audio-visual databases compiled by the authors.
