hi all,
im doin project in speech enhancement... so im in need of matlab code for wavelet based voiced/unvoiced classification algorithm of speech signals .. it includes the following steps, noise suppression filter, segmentation and preprocessin and this step is again divided into two categories 1.( application of 4level DWT, computation of per band energy, and ratio of high to low band energy,)2.high pass filterin and computation of zero crossing rate and then its median and then threshold), and finally the decision is made by comparing the energy ratio zcr and threshold..
so pz help me by sending matlab code..

Hi,

First try something & come back if any issues you have.
Mostly you wont get help for complete project that too without your effort.

Shan!
