Speaker change detection using joint audio-visual statistics
In this paper, we present an approach for speaker change detection in broadcast video using joint audio-visual scene change statistics. Our experiments indicate that using joint audio-visual statistics we achieve better recall without loss of precision as compared to purely audio domain approaches for speaker change detection. 1 Context In the emerging multimedia and ubiquitous computing applications there is a general awareness of the need to perform joint audio-visual analysis. Examples of such applications include speechreading 1, 6, 7, 8, 12 and general multimodal communication 3 . One of the fundamental goals in this emerging discipline is to model audio-visual events for the purposes of understanding, indexing and managing multimedia content. There is signi cant value in generating automatic transcripts and summarization of such audio-visual content. An example of such would be generating a textual transcription keywords automatically from the speech portions of the audio-visual...
