Iam doing my final year project based on "Speaker Identification using instantaneous frequencies" and we are planning to implement it in matlab environment. But we are currently held up with a problem. We are not able to get the instantaneous amplitude and frequency of the input speech signal. We have written the code for the first part for finding out the instantaneous amplitude and frequencie...

Hi I'm currently working on a project, Voice Recognition using neural network. The end result i want to get is the cepstral coefficient so that i can use them to train using neural network. Are there any probelm on this code? I hav problem debugging this line : pspectrum = powspec(samples, sr, wintime, hoptime, dither); How do i solve it? Thanks function [cepstra,aspectrum,pspectrum] = me...

Hi everybody; I want to tell you what i did and what i need. I made a data base including phonemes like '' -th,-sh, ai,-ea .." i recorded this phonemes in a wav file. I read a text and recorded it in a wav file. I have a system that you can process the speech with fft,dct and wavelet transform than you have two options for matching or comparing two speech datas. This options are DTW and Cross ...

Hey everyone, I'm working on training of HMMs for speech recognition using TIMIT database. Can someone tell me if there is a matlab code available for it? What should the topology of the HMM(HMm structure) be? Should it be a left to right(Baki's model) and a fully connected model( transitional probabilities between all the states? I appreciate any advice or help. Thank you Namr...
