Dear All, I am doing a project for speech recognition, which method will be good to compare two speechs and tell how much they are matched? I am trying using LPC and FFT, but the result is not so good, maybe I should do some quantiztion first, any idea? Thanks a lot! Rick |

Hi Rick,
For comparing the similarity of two speech signals the best tool would be
cross correlation.

FFT analysis gives you the frequency components but you miss the loaclized time properties. You can make use of wavelet decomposition and look at the features at different frequency sub-bands. Cross correlation is also a good tool, but you have to be good at interpreting the results.. --- In , "Rick Lee" <rlee@a...> wrote: > Dear All, > > I am doing a project for speech recognition, which method will be > good to compare two speechs and tell how much they are matched? > > I am trying using LPC and FFT, but the result is not so good, maybe I > should do some quantiztion first, any idea? > > Thanks a lot! > > Rick |
