Abstract (in Japanese) (See Japanese page) 
(in English) The multiple channel 2D-CSP method estimates sound source positions with a microphone-array. In this method, the estimation accuracy is degraded by reflections and reverberations in real environments. By measuring impulse response, it is easily to separate the direct and reflected sounds. However, in continuous signals, it is difficult to separate the direct and reflected sounds. On the other hand, VSS-UMCLMS method was proposed to achieve the blind impulse response estimation from observed continuous signals. Therefore, we propose a sound source localization method which introduce VSS-UMCLMS to multiple channel 2D-CSP. The proposed method can achieve the robust estimation of sound sources in reverberant environments. As a result of experimental evaluations, the effectiveness of the proposed method was confirmed.
