pitch detection of speech by wavelet - mahdieh ghazvini - Jun 10 5:57:00 2003

I am an undergraduate who has been working on my thesis about detecting pitch in speech signal using wavelet. I'd like to know what is the best method to do it.

Re: pitch detection of speech by wavelet - pravin kumar - Jun 12 1:55:00 2003

Hi, Detecting pitch using wavelets is by splitting the speech signal into multiple frequency bands by employing wavelet filters. The fundamental frequency subband contains pitch. This is called Sub-Band encoding. It is not as easy as what I have explained, as it invoves a bit of math behind it. But the matlab wavlet tool box would be a good startingpoint.
