Phonetic subspace mixture model for speaker diarization
I-Fan Chen, Shih-Sian Cheng, Hsin‐Min Wang · 2010
This paper presents an improved distance measure for speaker clustering in speaker diarization systems. The proposed phonetic subspace mixture (PSM) model introduces phonetic information to the ΔBIC distance measure. Therefore, the new PSM model-based ΔBIC distance measure can remove the effect of phonetic content on the diarization results. The typical ΔBIC distance measure can be seen as a special case of the new ΔBIC distance measure. Our experiment results show that the new distance measurement consistently improves the speaker diarization performance on three datasets.
