ABSTRACT:
A system and method for indexing multimedia files utilizes audio characteristics of predefined audio content contained in selected multimedia segments of the multimedia files to distinguish the selected multimedia segments. In the exemplary embodiment, the predefined audio content is speech contained in video segments of video files. Furthermore, the audio characteristics are speaker characteristics. The speech-containing video segments are detected by analyzing the audio contents of the video files. The audio contents of the speech-containing video segments are then characterized to distinguish the video segments according to speakers. The indexing of speech-containing video segments based on speakers allows users to selectively access video segments that contain speech from a particular speaker without having to manually search all the speech-containing video segments.
