| 摘 要： | 唇同步效果影响人类对语言的理解。着重研究汉语语音和口型的唇同步，将汉语对应口型划分为4类、两种状态(极点态与过渡态)，得出汉语唇同步验证是对极点态音频和极点态视频的同步验证，提出基于极点态音频／视频知识库的唇同步识别与验证模型，分别阐述了模型中音频／视频特征分析子系统，提出了可以将基于运动对象识别的帧间差法与嘴唇形状、颜色和运动特征结合，实现嘴唇精确定位，最后给出唇同步验证过程。

| Abstract: | Quality of lip synchronization has effect on human communication. Lip synchronization between Chinese speech and lip shape is the central topic. Mouth shape corresponding to Chinese speech is classified into four classes and two states (extreme state and transition state). It's considered that to ensure the lip synchronization between Chinese audio and lip movement is to ensure the synchronization between audios and videos of extreme state. A model of lip synchronization verification is proposed and the subsystems of the model are described. Then it is suggested that together with shape, color and movement attributes of lips, and movement-based object recognition method can be used to get the accurate position of mouth. |
