Popis: Seck, Mouhamadou, Blouet, Raphael, and Bimbot, Frederic, The IRISA/ELISA Speaker Detection and Tracking Systems for the NIST'99 Evaluation Campaign, Digital Signal Processing10(2000), 154?171.This article presents the various systems developed by IRISA, around the ELISA platform, for the NIST'99 evaluation campaign in speaker detection and tracking. The main features of these systems are the implementation of a Maximum A Posteriori approach for speaker model estimation, an utterance-length dependent z-normalization scheme for test segment scoring, a speaker/world mixture model for addressing the two-speaker detection task, and the use of a change point detection method for speaker tracking. The performance of the various systems on the NIST'99 evaluation data are reported.
