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. Hope this helps, Pravin --- mahdieh ghazvini <> wrote: > 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. __________________________________ |
