Abstract

This paper describes the winning systems developed by theBUT team for the four tracks of the Second DIHARD SpeechDiarization Challenge. For tracks 1 and 2 the systems weremainly based on performing agglomerative hierarchical clustering(AHC) of x-vectors, followed by another x-vectorclustering based on Bayes hidden Markov model and variationalBayes inference. We provide a comparison of theimprovement given by each step and share the implementationof the core of the system. For tracks 3 and 4 withrecordings from the Fifth CHiME Challenge, we exploreddifferent approaches for doing multi-channel diarization andour best performance was obtained when applying AHC onthe fusion of per channel probabilistic linear discriminantanalysis scores.
