Primary research on the viseme system in Standard Chinese

The study of traditional phonetics indicates the shape of lips takes important effect on the articulations of consonants and vowels. [1]. AVSP (Audio-Visual Speech Processing) can improve the naturalness of synthetical speech and recognition rate of the speech recognition system. Especially in computer-synthesized face, the movements of lip-shape play a crucial role. The present research aims to theorize a system of lip-shape variety comparison of the phoneme system of Standard Chinese. A new terminology“viseme system” is given to this system. A small-scale visual speech database was created firstly and the viseme system in Standard Chinese is concluded based on the database and through a series of statistics methods.
