摘要： PROBLEM TO BE SOLVED: To accurately, rapidly and easily decide whether an intended person is speaking or not, without imposing an unnecessary burden on a speaker, in surroundings wherein voice of others or sound from audio equipment or the like exists. SOLUTION: A deformation degree of lips is automatically acquired from an image of an object person 1 picked up by an object person imaging part 2, while an envelope curve of a voice is automatically acquired from the voice recorded by a sound recording part 3. A pattern matching part 8 calculates a similarity between time-series change patterns of the deformation degree of the lips and the envelope curve of the voice to identify a speaker. Thereby, the speaker can be identified without imposing an unnecessary burden on the object person 1, with a small information-processing load, at a high identification rate.
