| Abstract(in English) | We deal with the problems of blind source separation, dereverberation, audio event detection and DOA estimation. We previously proposed the multichannel factorial hidden Markov model, and simultaneously solved those problems. In this paper, we apply the DOA mixture model for modeling the spatial correlation matrix. Experimental results revealed that the proposed method was superior to our previous method in terms of the signal-to-distortion ratios of separated signals. |
