Original Abstract

This paper presents a simplified version of the previously proposeddiarization algorithm based on Bayesian Hidden MarkovModels, which uses Variational Bayesian inference for very fastand robust clustering of x-vector (neural network based speakerembeddings). The presented results show that this clusteringalgorithm provides significant improvements in diarization performanceas compared to the previously used AgglomerativeHierarchical Clustering. The output of this system can be furtheremployed as an initialization for a second stage VB diarizationsystem, using frame-wise MFCC features as input, to obtainoptimal results.
