Abstract
The present disclosure proposes a method and an apparatus to enhance reverberated speech by applying reverberation detection in conjunction with reverberation cancellation. The reverberation detection is based on Kurtosis of cross correlation of LPC residue and outputs the result of the reverberation detection to the reverberation cancelling system. The reverberation cancellation receives the result from the reverberation detection, and the cancellation is based on dual adaptive filtering in LP residue and time domain.
