PROBLEM TO BE SOLVED: To provide a means making it possible to precisely retrieve a speaking section of a desired speaker even when video and audio include a part wherein a plurality of speakers speak at the same time.;SOLUTION: In a speaker speech registration phase, not only feature quantities of the voice of a speaker himself/herself, but also feature quantities of a voice composed of speech signals of a plurality of speakers are extracted and registered in a speech database 1. In a speaker retrieval phase, an input speech signal to be retrieved is segmented into short sections and feature quantities of the respective short sections are collated with feature quantities in the speech database 1 to recognize speakers. In a speaking section determination phase, retrieval results of speakers of the respective short sections are totalized in every fixed number of short sections and speaking sections of the speakers are found according to appearance frequencies of the speakers. In a speaker information display phase, the retrieval results of the speaking section are displayed.;COPYRIGHT: (C)2004,JPO
