Hello,
I'm currently finding documentations about feature extraction algorithm used in the front-end of CMU Sphinx Architecture. What is the latest algorithm? I've recently found that PNCC is used. Is it true?

  The code uses simplified PNCC versoin, no gammatone filterbank and less intelligent masking but otherwise the ideas are similar.
