1) Why mel-filterbank is important in speech analysis?
2) What is the main function of mel-filterbank and what happen to the input speech signal if we just ignore from doing this part?

I'm using FIR 2channel filter bank in MATLAB for wavelet packet filter bank,is it right?I need to design different filters from embeded ones to improve the performance.May you guide me?
Thanks in Advance

I need to make a function for filtering dtmf-signals through a filterbank and detecting the frequencies and then figuring out which keys they correspond to.
detect=0; %sets detect to 0 before checking
%now, if i've understood it correc

I wana implement (delayless)adaptive subband noise cancellation using polyphase filterbanks.
any help (thesis-paper-matlab source code-project report,..) would be appreciated.
I have problem in starting polyphast filterbank implementation in matlab :cry:
Need urgent help !!!!

Do a few searches for "template matching" in speech recognition applications.
Since you don't need continuous recognition or transcription you might not need something as complicated as Hidden Markov Models or Artificial Neural Nets. Maybe you want isolated word recognition?
filterbank analysis comes to mind as does Dynamic Programming as in

if u r interested only in extracting a particular band of frequencies have a look at lyons cochlear model.
its a IIR filter bank with just 2 nd order filters.
u can google for Malcolm sanley or lyons cochlear model.
Matlab also has a filterbank implementation function. but only FIR.

This MATLAB program is for making a suitable wavelet kernel
It derives the Low pass filter by sampling from analog raised cosine function in frequency domain and taking ifft from this function to yield the impulse response. (other filters are derived using orthogonal relations).
first i wnat know if the filter design method has any problems?
