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:
HList data/train/sig/Gr_F2_dhAsos_R1_aso.wav
But got:
ERROR [+1113] IsWave: cannot read HTK Header in File data/train/sig/Gr_F2_dhAsos_R1_aso.wav
FATAL ERROR - Terminating program HList
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.

>TARGETKIND = MFCC_0_D_A
see this post: MFCC_D_N_Z_0 format

Hi
I have the same exacrt problem while trying to get the .mfcc files. I however have been using HTK fromat ( .sig ) yet get the same series of errors you got. I was wondering if you could figure out what the problem was. I see you have posted this quite a while ago.
Thank you!
