Abstract
In this paper, a way to classify and edit lengthy speech material in sound scene, including various sounds such as TV/radio or meeting and discussion speech, is discussed on the premise of no prior information hypothesis. The proposed method is comprised of two technical parts. One is voice clustering, based on the vector quantization (VQ) distortion as the criterion, and the other is automatic adaptive threshold estimation. This application is, especially, convenient and fast for creating the speech database or speech searching using the audio data. The experimental results show the F-measure value of 94.13% on the conversation speech 1.67 hours, and a clustering rate of 84.1% on speaker sound of the 30 minutes from phone calling voice including various noises. Without a training model and a short utterance, we conformed that the VQ distortion measure and the dynamic threshold estimating approach are easy to implement and convenient to one-set recording sound scene (category) clustering.
