Abstract :
A real-time synthetic talking head provides a natural communication interface for human-machine interaction. In this paper, two driving schemes for Mandarin are proposed. One is a speech-driven method using wavelet network to map audio signals to visual movements, the other is a hybrid driving scheme making use of linguistic analysis. Based on this framework, a Web browser is successfully built up, in which a virtual newsreader can read Chinese Web articles in real time
