This work applies a viseme-driven talking head in a pronunciation training system. The aim is to create a pronunciation assistant to complement traditional methods and to assist the work of a human language tutor. Visual speech can be valuable in speech tutoring applications because vision benefits human speech perception, for three reasons as suggested by Summerfield (Summerfield, 1987): It helps speaker localization, it contains speech segmental information that supplements the audio, and it provides complementary information about the place of articulation. This study aims to elucidate the benefits of visual speech in language learning.
