Hi everyone,
I have shared speech recognition code in
https://github.com/gtiwari333/speech-recognition-java-hidden-markov-model-vq-mfcc
You can find complete source code for speech recognition using  HMM, VQ, MFCC ( Hidden markov model, Vector Quantization and Mel Filter Cepstral Coefficient). Feel free to use and modify this code.

The project report that accompanies this code is here.
