Hello,

I'm trying to get myself trained on HTK with a baby data set.  Data was recorded at 44k, 16bit sampling rate on a Sony Devices 722 digital recorder in a soundproof booth in a .wav format.  These were processed first by PRAAT (as part of a different phonetic study), in case that makes a difference.

My problem arises when I try to use HCopy to convert the files to .mfcc.

I've read the forum post "converting .wav to .mfc using HCopy in HTK" (http://www.voxforge.org/home/forums/message-boards/speech-recognition-engines/converting-.wav-to-.mfc-using-hcopy-in-htk), but this doesn't solve my problem.

I had heard that there are problems using .wav with HTK, and so I converted my .wav files to .htk format using sox; either way I get the same problem. 

My analysis.conf file is as follows: (when I tried this with .wav files I changed SOURCEFORMAT to WAV).

***

# Acoustical analysis configuration file

#

SOURCEFORMAT = HTK # Format of speech files

TARGETKIND = MFCC_0_D_A # Identifier of the coefficients to use

#Unit = 0.1 micro-second

WINDOWSIZE = 250000.0 # = 25 ms = length of a time frame

TARGETRATE = 100000.0 # = 10 ms = frame periodicity

NUMCEPS = 12 # Number of MFCC coeffs (here from c1 to c12)

USEHAMMING = T # Use of Hamming function for windowing frames

PREEMCOEF = 0.97 # Pre-emphasis coefficient

NUMCHANS = 26 # Number of filterbank channels

CEPLIFTER = 22 # Length of cepstral filtering

ENORMALISE = T # Normalise intensity of data

***

I use the following command:

HCopy -A -D -T 1 C analysis/analysis.conf -S targetlist_htk.txt

***

It seems that the more promising route is to go with the HTK files.  I tried the following:

So it seems that my .htk files work, while my .wav ones are not readable by HTK at all.

I would appreciate any help possible.  I think I've provided all the necessary information, but in case it matters, I'm running HTK on Linux (OpenSUSE).

Thanks very much in advance for any help.
