Speech quality may significantly deteriorate in the presence of interference especially when the speech signal is also subject to reverberation. Consequently modern communication systems such as cellular phones employ some speech enhancement procedure at the preprocessing stage prior to further processing . speech coding . Generally the performance of single-microphone techniques is limited since these techniques can utilize only spectral information. Especially for the dereverberation problem no adequate single-microphone enhancement techniques are presently available. Hence in many applications such as hands-free mobile .
