A Modified Methed of Speech Denoising on Wavelet Transform Momain

LI Gao-feng,YIN Jun-xun,XU Yan  
According to the different characteristics between signal and noise on wavelet transform domain we present a modified mothed of speech denoising. In order to reduce noise in reconstructing speech signal we use a changing threshold to remove noise components from the different scale coefficients of noisy speech.
