Hi Friends,

I am presently working on LPC10 Vocoder. If any one has the MATLAB code for LPC10
then please send it to me.

I also need a MATLAB code for Pitch Estimation.

Hi,

Please send me the C code for LPC10.

Do u have any MATLAB Function for calculating Pitch in a 20ms frame of speech?

Bye...

ok, here's a script in Matlab it's about the simulation of a GSM norme, you can find in the first part the emission of signals and in the second the LPC code and the calcul of pitch too

Hi
here is a matlab source code. I used it (PROCLPC.m) in my speech project.

I have done a speech project to get LPC , PARCOR and LSF coefficeints for (L=4 , 12 and 50 : L is the order of all pole filter ) to compare the effect of channel noise on different presentation of LPC coeffients. let me know if you want to see that.

HELLO RAMIN,

I AM CURRENTLY WORKING IN LPC. I USED THE SAME SOURCE CODE-PROCLPC.m . COULD YOU PLEASE HELP ME WITH THE CALCULATION OF PREDICTION GAIN/PREDICTION ERROR VARIANCE WITH THIS PROGRAM. I SUPPOSE YOU HAVE WORKED ON THAT TOO.
THANKS A LOT ......
