Wavelet Subband coding for speaker recognition

fn extracts wavelet feature vector which could be used for speaker recogniton from speech signal.

The fn will calculated subband energes as given in the att tech paper of ruhi sarikaya and others. the fn also calculates the DCT part. using this fn and other algo for pattern classification(VQ,GMM) speaker identification could be achived. the progress in extraction is also indicated by progress bar.
