Definition
Speaker segmentation is the process of partitioning an input audio stream into acoustically homogeneous segments according to the speaker identity. A typical speaker segmentation system finds potential speaker change points using the audio characteristics.
Introduction
Segmenting an audio–visual stream by its constituent speakers is essential in many application domains. First, for audio–visual documents, speaker changes are often considered natural points around which to structure the document for navigation by listeners (speaker indexing). In broadcast news, for example, speaker changes typically coincide with story changes or transitions. Audio recordings of meetings, presentations, and panel discussions are also examples where organizing audio segments by speaker identity can provide useful navigational cues to listeners. Furthermore, an accurate speaker segmentation system is also necessary for...
