Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we give an analysis on the amount of musical noise for blind speech extraction based on a generalized minimum mean-square error (MMSE) short-time spectral amplitude estimator. In the previous studies, blind spatial subtraction array (BSSA) has been proposed as a method of blind speech extraction. However, a serious problem, musical noise due to nonlinear signal processing, exists in BSSA. To solve this problem, we introduce the MMSE estimator with optimizable speech model and inhomogeneous error criterion to BSSA, and discuss the amount of musical noise generated in the proposed method via theoretical analysis and simulation-based experiments.
