LPCC feature extraction for audio signal

*Hello,

I go through this code MFCC feature extraction for MFCC feature extraction for speech signal. How we can implement it for multiple audio signals and get the feature vectors and for implementing LPCC to get its features vectors.*

Thanks for links. Actually i want to implement LPCC feature extraction, the link are for LPC features. How we can modify the above mfcc code to get LPCC cepstrum coefficients.

I want to do signal processing in matlab. The code of LPC is available in this link https://www.mathworks.com/help/dsp/examples/lpc-analysis-and-synthesis-of-speech.html. The code is working fine as it is but when I separate the analysis and synthesis part it is not recovering the speech. I am storing the output of LPC analysis i-e sigk and siglpc in mat files and then again reading the data of sigk and siglpc from mat files and giving data to LPC synthesis but speech is not recovering back.
