For a given mixture of speech and noise; an ideal binary time-frequency mask is constructed by comparing speech energy and noise energy within local time-frequency units. It is observed that listeners achieve nearly perfect speech recognition from gated noise with binary gains prescribed by the ideal binary mask. Only 16 filter channels and a frame rate of 100 Hz are sufficient for high intelligibility. The results show that; despite a dramatic reduction of speech information; a pattern of binary gains provides an adequate basis for speech perception. © 2008 Acoustical Society of America;
