| Abstract(in English) | We proposed a novel speaker clustering method by estimating the structure of a fully Bayesian utterance generative model with a hierarchical structure. We defined the hierarchical generative model as a mixture of GMMs, which represent each speaker's distribution. We approximately estimated this model by introducing a sampling method because strict estimation of this model was infeasible. From speaker clustering experiments, we showed that the proposed method was effective to the data in which the number of utterances varied from speaker to speaker, while the conventional method caused significant degradation in clustering accuracy for these data. |
