This paper addresses the problem of single-channel speech enhancement using spectral subtraction method. The proposed approach is directed toward combining modified a priori SNR based spectral subtraction algorithm with iterative spectral subtraction algorithm. Experimental results show that the method is quite effective in speech enhancement as it can cancel a large mount of background noise with little distortion to speech signals,and that the method greatly lowered music noise.
