摘要：It is well known that the performance of an automatic speaker recognition system degrades in the presence of noise. The degradation of voice due to the presence of additive background noise and convolutive noise causes severe difficulties in various communication environments. This paper addresses the problem of reduction of additive as well as convolutive noise in speech. This paper explores a Spectral Subtraction approach together with the Cepstral Mean Normalization method for noise reduction.
