一个基于SAPI5.0的中文语音动画系统

A Chinese Speech Animation System Based on SAPI5.0

在已经实现的"一个MPEG-4兼容的人脸动画系统"和基于KD2000的"一个MPEG-4兼容的语音动画系统"的基础上，又设计并实现了"一个基于SAPI5.0的中文语音动画系统"。该文介绍该系统的设计思想和实现技术，包括定义中文可视音素、得到中文可视音素、估算可视音素的持续时间、处理表情标签、语音与动画同步等。语音动画系统在普通微机上就能够产生带有表情的高质量的语音动画。

After developing a MPEG-4 compliant facial animation system and a MPEG-4 compliant speech animation system based on KD2000, the authors designed and implemented a Chinese speech animation system based on SAPI5.0. This paper describes the design and implementation of the system, including defining and getting Chinese viseme, estimating viseme time duration, handling expression label, and speech-animation synchronization. The system can produce high-quality speech animation with expression in an ordinary micro computer.
