Abstract

We present an algorithm for reverberant speech enhancement using one microphone. We first propose a novel pitch-based reverberation measure for estimating reverberation time (RT60) based on the distribution of relative time lags. This measure of pitch strength correlates with reverberation and decreases systematically as detrimental effects of reverberation on harmonic structure increase. Then a reverberant speech enhancement method is developed to estimate and subtract later echo components. The results show that our approach appreciably reduces reverberation effects.
