A Speech Rate Related Lip Movement Model for Speech Animation

Wei Zhou, Zengfu Wang

University of Science & Technology of China, China

A novel lip movement model related to speech rate is proposed in this paper. The model is constructed based on the research results on the viscoelasticity of skin-muscle tissue and the quantitative relationship between lip muscle force and speech rate. In order to show the validity of the model, we have applied it to our Chinese speech animation system. The experimental results show that our system can synthesize the individualized speech animation with high naturalness at different speech rates.
