Abstract(in English) | Speech has two types of information, such as phoneme and speaker. If these information are separated, robust speaker clustering can be achieved. It is necessary to suppress the phonetic information for each utterance because variance of utterance duration is large in multi-party conversation. We propose a speaker clustering method using Gaussian mixture model in flexibly selected speaker subspace based on variance of intra-utterance. We carried out speaker clustering experiments compared with conventional methods based on Bayesian information criterion and Gaussian mixture model in an observation space. The experimental results showed that the proposed method can achieve higher clustering accuracy than conventional methods. |
