Abstract(in English)	This paper describes an extended subband-crosscorrelation (SBXCOR) analysis to improve the robustness against noise. The SBXCOR analysis, which has been already proposed, is a binaural speech processing technique using two input signals like the auditory system, and extracts the synchronicity associated with the inverse of the center frequency fF^<-1>_ in each subband. In this paper, by taking a weighted sum of crosscorrelation at the integral multiples of F^<-1>_ with the power of a constant α, an extended SBXCOR is proposed so as to capture more synchronicity between binaural signals. The experimental results using a DTW word recognizer show that the performance of the extended SBXCOR is equal to or more than that of the conventional one, and that the equivalent SNR improvement is about 7dB under SNR 0dB. Furthermore, the experimental results using speech signals recorded by a microphone array show that the MDW is effective under a real condition.
