Hi!I have been making a speaker verification system using Matlab.Unfortunately,when I record wav audio clips via a microphone,white noise is present in the wav files.

How do I remove the white noise to enable a more accurate speaker verification system?

My code for reading the wav file is as below

[s,fs]=wavread('train\joe.wav');

I was hoping to remove the white noise from the amplitude values (s) such that the filtered signal becomes one of the input parameters in my Mel-Frequency Cepstrum Co-efficients as shown below

v = mfcc(s, fs); where s is the filtered signal.

Please help me and I shall be infinitely grateful.Thanks in advance.
