Abstract(in English) This report describes a simple method for noise suppression under distant-talking environment, to deal with relative change of sound source location caused by the movement of a microphone array and a sound source. This method uses an iterative time difference compensation method, spatial filtering, and time-frequency masking. To evaluate its effectiveness, the experiments are carried out with moving sound source under noisy environment. The results of experiments show that the noise suppression performance of the method is enough high, and the PESQ value improved more than the noise suppressor of EVRC.
