Application of Speech Driven Lip Animation Based on HTK
Lip synchronization is one of the key issues in speech driven face animation system.First selectes as recognition unit.Through a method based on rigorous initial and final modeling,uses HTK syllable to get syllable list and time information.Then uses the lip library and syllable-lip mapping table to obtain lip sequence corresponding with syllable sequence.Finally,speech driven face animation is achieved by interpolating and playing lip sequence with time information.Experimental results show that this method not only sharply reduces the number of models,but also recognizes and plots out the syllable and time information accurately in speech files.It effectively realizes the synchronization of speech and lip animation.
