Speaker Identification using instantaneous frequencies

Started by ramy...@gmail.com January 5, 2009
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 frequencies. But our code gives the output plot only for inbuilt matlab wav files and not for our own recorded speech signal. We recorded our voice in wav format using both windows sound recorder and also wavrecord function in matlab. Still we are not able to proceed with our project. Our plot shows zero for instantaneous frequency.

Please help us in collecting the speech samples and finding the instantaneous frequency.
Reply if u know any other means of recording and processing the input speech samples
Thanx in advance.

What is ur sampling rate and window size used for spectrum analysis. U sh'd look up both type of files (ur & matlab) in some free-ware speech s/w to verify the file-formats (although I think standard .wav format sh'd not have any problem).

just right click on the matlab wav files and see its properties then change
your sound wav properties. u will get the output.
