| Abstract: | Dereverberation of speech signal is applied to many areas including communication and speech recognition. The research progress on the problem is reviewed. The phenomena of sound reverberation and the principle of dereverberation with cepstrum transform are addressed. A dereverberation method using microphone array in cepstrum domain is briefly introduced. |
