Hi i am new at HTK and have followed "A Tutorial Example of Using HTK" in The HTK Book from http://htk.eng.cam.ac.uk/

I have gotten to the point where i have to use "HCompV" (3.2.1 Step 6 - Creating Flat Start Monophones )

i have "cd" to my working dir and my command goes as

HCompV -C wav_config_HCompV -f 0.01 -m -S train.silmodel.scp -M hmm0 proto.silmodel

(Dont mind the weird names ive made a few attempts to get to here and renamed new file versions with new names to keep the old)

My "wav_config_HCompV" Contains

TARGETKIND = MFCC_0_D_A
TARGETRATE = 100000.0
SAVECOMPRESSED = T
SAVEWITHCRC = T
WINDOWSIZE = 250000.0
USEHAMMING = T
PREEMCOEF = 0.97
NUMCHANS = 26
CEPLIFTER = 22
NUMCEPS = 12

My "train.silmodel.scp" contains

"/home/pi/HTK/htk.eng.cam.ac.uk/HTK Book/train/wav-2/S0001.wav"
"/home/pi/HTK/htk.eng.cam.ac.uk/HTK Book/train/wav-2/S0002.wav"
"/home/pi/HTK/htk.eng.cam.ac.uk/HTK Book/train/wav-2/S0003.wav"
"/home/pi/HTK/htk.eng.cam.ac.uk/HTK Book/train/wav-2/S0004.wav"
"/home/pi/HTK/htk.eng.cam.ac.uk/HTK Book/train/wav-2/S0005.wav"
"/home/pi/HTK/htk.eng.cam.ac.uk/HTK Book/train/wav-2/S0006.wav"
"/home/pi/HTK/htk.eng.cam.ac.uk/HTK Book/train/wav-2/S0007.wav"
etc...

and my "proto.silmodel" contains 

~o <VecSize> 39 <MFCC_0_D_A>
~h "proto

0.0 0.0 0.0 0.7 0.3 
0.0 0.0 0.0 0.0 0.0 
<EndHMM>

When i run the command i get the error

ERROR [+5013]  ReadString: String too long
FATAL ERROR - Terminating program HCompV

Which i find rather odd. Since on pages like understanding htk error messages

i end up finding not in "HCompV" error message but "HLed" error saying 

ERROR [+5013] ReadString: String too long
FATAL ERROR - Terminating program HLEd

and the solution should be 

Make changes to the pronunciation dictionary:
Replace all multiple spaces with single space;
Replace all tabs with single space;
Put a '\' before every double quote ("); %"
Put a '\' before any dictionary entry beginning with single quote (')

i cant see how this error code in any way has anything to do with HCompV and no other place on the net have i found anything relating to my weird error. Is there any out there who has a clue ?

i dont seem to have any dictionary in this comman so it doest add up.

Ty for reading so for and best regards, Darkyere

  • The file "train.silmodel.scp" does not look correct. Each line should have the path to a .wav file followed by the path to the corresponding .mfc file. Your lines show a wav path preceded by an htk directory. The space in "HTK Book" likely is causing a parse problem. – Colin Beckingham Jan 24 '17 at 14:59

This error is caused by a missing new line in the end of some of the input files. Make sure that each input file ends with a newline. You can use any good text editor for that.

Input files to HCompV have to be in mfc format, not wav. Convert all wavs to mfc via HCopy and change train.silmodel.scp file indicating paths of mfc files.
