| Abstract(in English) | Lipreading is the technique to recognize speaker's utterances from the motion with changing shape of the mouth. Although most of previous approaches to lipreading focus on the limited region of the mouth, utterances of some phonemes often accompany with the motion of surrounding areas together with the mouth movement. In this paper, we have compared four regions: (A) entire face region, (B) the region that the eyes and the nose are removed from the entire face region, (C) mouth and adjacent region, and (D) mouth region. Experimental results of word recognition and vowel/consonant recognition show that most of vowel recognition using the region (B) results in the highest performance, while different regions output the best performance on consonant recognition. |
