Help required regarding sound identification using feature extraction and classification methods

Hello,

I am doing research on identifying objects based on their sounds. For this i have to use feature extraction methods like MFCC, HLA and for calssification using SVM and HMM. I want to know about training procedure. When training step will occur before feature extraction or after this. And how we train our data in Matlab. Can anybody shares good tutorial related to this or matlab code related to this.

Anybody who has worked on Harmonic line association algorithm then please share tutorial related to this.

It would be very helpful if you can share MFCC and SVM matlab codes which can identify each sound. If anybody has worked on this then please help me in this regard.

Waiting for your help.

Thanks
