Abstract(in English) In this paper, we apply mouth-shape-approach to Japanese speaker's utterance profile for lip reading.The novel point is to propose automatic detection of consonant-key-frames. To detect the consonant-key-frames by time series of profile feature vector which is defined the difference value of distance of lips and projection length of lower lip. This approach provides an extension of mouth-shape-code time series. The mouth-shape recognition of key-frames is conducted by five profile shape features; the height of upper lip and lower lip, the projection length of upper and lower lip points, and the angle of lips. We apply DP-matching to the recognized word code string of key-frames and a candidate word code string, then search the nearest word as the result. Recognition experiments using two sets of target 27 words commonly used in dairy conversation, and adding 10 pairs of similar words to them are conducted. The proposed method attained 90.4%, and 86.7% for these word set respectively.
