Ideally, the system aims to create one pure cluster for each speaker. The HMM is ergodic in nature with a minimum duration topology. The final number of clusters is determined automatically by merging closest clusters and retraining this new cluster, until a decrease in likelihood is observed. In the same framework, we also examine the effect of using only the features from highly voiced frames as a means of improving the robustness and computational complexity of the algorithm. The proposed system is assessed on the 1996 HUB-4 evaluation test set in terms of both cluster and speaker purity. It is shown that the number of clusters found often correspond to the actual number of speakers.}, pdf = {https://publications.idiap.ch/attachments/reports/2002/rr02-07.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2002/rr02-07.ps.gz}, ipdinar={2002}, ipdmembership={speech}, language={English}, }
