Abstract: In this paper, the system submitted by the UVigo-GTM for the Albayzin 2010 Speaker Diarization Evaluation is described. This system is built upon the speaker segmentation system presented in our ICASSP 2010 paper. Specifically, the system uses a poisson-based false alarm reduction strategy. Then, the speaker segmentation strategy assumes that the occurrence of changes constitute a Poisson process, so changes will be discarded with a probability that follows a Poisson cumulative density function. The speaker clustering step we use an agglomerative clustering approach in which the speech segments are merged until reaching a stopping point.
