Abstract (in Japanese) (See Japanese page) 
(in English) We have already proposed a musical-noise-free blind speech extraction method using a microphone array that can be applied to nonstationary noise. This method generates no musical noise even for a high SNR. In this paper, we conduct objective and subjective evaluation with real traffic noise and railway station noise, where evaluate signals are processed by representative single channel speech enhancement methods, conventional blind speech extraction method, and our proposed methods. From objective and subjective evaluations, we reveal that the proposed method outperforms the conventional method.
