This paper considers blind speech separation and recognition for human robot interaction in reverberant environment. In the proposed system, the speech sources whose number is more than the number of mixtures are separated by MMSE-criteria and recognized by HMM-based speech recognizer. Experimental result shows the superiority of the proposed system.
