Hai everybody, Can anybody suggest me a method to optimize the ACELP search in AMR-NB codec?(DFTS method) so that there is no reduction in speech quality when compared to original? I have already gone through some IEEE papers. But speech quality is not maintained. They reduced the

Hi, I am currently doing this project of Classification and categorisation on the basis of speech. I have to sort the samples into male or female and into age categories on the basis of the speech samples. For this i have used pitch as a fetaure and on this i

hai, I am searching for a fast convolution algorithm which has order less than O(MN). I have already tried FFT. Is there any other method available to compute the correlation in a faster manner? Awaiting reponse.. venkat ? Mistakes are not end of the world

hi all, i am puzzled about the use of long-time predictor in celp. i see in some implementations, there is a long-time predictor (ltp) but in others, eg fs-1016, there isn't. if I understand correctly, the ltp is used to compute the gain. but why is there a need

hi, I read that the "analysed" filter is a FIR (stability is ensure) but the synthesized filter is a IIR filter (inverse filter). is that right? I don't see how it is so? and if it is so, how is stability ensured? rgds, tk
