  • Abstract
    A novel technique for voice activity detection of a moving speaker in adverse conditions using an array of microphones. The proposed approach is based on the generalised likelihood ratio test applied to far-field, wideband moving sources (W-GLRT). It is shown that under certain distributional assumptions the W-GLRT provides a statistical framework for the evaluation of direction of arrival (DOA) measurements against spurious DOAs and which leads to statistical speech activity detection.
