If desired speech source is located at different position from interference, it is possible to exploit spatial selectivity for reliable speech detection. In this paper, we propose a voice activity detector (VAD) for the microphone array system, using spatial information obtained by the eigendecomposition of multi-channel correlation matrix. We use the phase vector as a measure for VAD, which is derived from the principal eigenvector. Voice activity is detected by the log likelihood ratio test… CONTINUE READING
