Abstract :
We utilize speech information to improve the quality of audio/visual communications, such as videotelephony, videoconferencing, and multimedia. In particular, marriage of speech processing and image processing can solve problems related to lip synchronization. Two main techniques proposed in this paper are: speech-assisted interpolation and speech-assisted coding of talking head video. Audio/video sequences are presented to demonstrate our techniques
