Abstract We propose an integrative method of recognizing gestures such as pointing, accompanying speech. Speech generated simultaneously with gestures can assist in the recognition of gestures, and since this occurs in a complementary manner, gestures can also assist in the recognition of speech. Our integrative recognition method uses a probability distribution which expresses the distribution of the time interval between the starting times of gestures and of the corresponding utterances. We evaluate the rate of improvement of the proposed integrative recognition method with a task involving the solution of a geometry problem.
