Speech signals recorded with a distant microphone usually contain reverberation, which degrades the fidelity and intelligibility of speech, and the recognition performance of automatic speech recognition systems. A multi-channel speech dereverberation algorithm is presented which reduces spectral coloration and late reverberation. A spatially averaged amplitude spectrum is used to estimate the instantaneous amplitude spectrum of the clean speech signal, which is then further enhanced using an… CONTINUE READING
