voice _unvoice detector and remover - blasottolo - Sep 3 10:06:30 2007

Hi, i am looking for some matlab sources about voice unvoice detection 
into wave file (with quite high noise).
Also some routine to remove the unvoice and noisy segments.

Thanks a lot for your help!!!

Hi, Blasottolo

A typical way of doing this would to be to consider for example zero crossing rates and LPC
residual (if the noise is white). A simple bayesian classifier will can give the result.
