Original Abstract
This paper describes the system developed by the BUT team for thefourth track of the VoxCeleb Speaker Recognition Challenge, focusingon diarization on the VoxConverse dataset. The system consistsof signal pre-processing, voice activity detection, speaker embeddingextraction, an initial agglomerative hierarchical clusteringfollowed by diarization using a Bayesian hidden Markov model, areclustering step based on per-speaker global embeddings and overlappedspeech detection and handling. We provide comparisons foreach of the steps and share the implementation of the most relevantmodules of our system. Our system scored second in the challengein terms of the primary metric (diarization error rate) and first accordingto the secondary metric (Jaccard error rate).
