Hello everybody,
It is the first time I use HTK for speech recognition, and I'm trying to learn how to build an HMM model. But, I have one problem and I do not how to solve it. It is related to my speech files. I have converted my source files from RAW format to WAV in order to use them with HTK (using sox under UNIX), and before typing HCopy to create the mfc files, I would like to listen my wav files, using play, but an error occurs. Could anybody help me? Thank you.
play prueba.wav

HCopy can read raw audio directly - you need to change your sourceformat to equal raw.

Can you play any audio on your PC? have you tried with 'aplay' or Audacity?
