ABSTRACT:
A system and method for unsupervised clustering of audio data segments in an audio data recording containing speech from multiple speakers including the steps of: 1) providing a portion of the audio data containing speech from all of the speakers; 2) forming initial clusters by dividing the portion of the audio data into segments, each of which includes an ordered data set; 3) computing the pairwise distance between each pair of clusters using a likelihood ration independent of the order of data within the segments; and 4) combining into a new cluster the two clusters with a minimum pairwise distance. These steps are repeated until a number of clusters equal to the number of speakers is obtained.
