Abstract

This paper is to prove that lip-movement is an available channel for information acquiring. The reasoning is given by describing two kinds of valid applications, which are constructed on lip movement information only. One is lip-reading, the other is lip-movement utterance recognition. The accuracy of the former system with speaker-dependent could achieve 68%, and of the latter achieves over 99.5% for test-independent (TI) and nearly 100% for test-dependent (TD) in experiments till now. From this conclusion, it could be easily got that lip-reading channel is an effective one and can be applied independently.
