通过对语音和唇形的信号采集,设计了12个外唇线关键点和9个内唇线关键点的提取方案,同时建立起语音、唇形数据库,并对其进行参数提取和统计分析,从而建立了汉语普通话语音、唇型之间的关联模型,在此基础上实现了语音驱动的唇形合成系统。
Based on the acquisition of speech and lip signal, this paper designs an extraction program about 12 key points outside lip contour,and nine key points in inside lip contour. A speech and lip database has been built, through which the parameter extraction and statistical analysis can be realized so as to build the correlation models about pronunciation of mandarin and lip shaped. The voice-driven lip synthesis system can be set up on this basis.
