Problem with HCompV - HTK

Hello everyone,

I'm trying to train the 3-state left-to-right HMM models for speech recognition. Each acoustic feature vector is 39-dimentional which consists of MFCCs, delta and acceleration coefficients (MFCC_D_A)
 
I have used the command as in the HTK book (version 3.2.1)
 
HCompV -C config -f 0.01 -m -S train.scp -M hmm0 proto
 
I have this problem with HCompV, the errors are:
 

HMM Def Error: GetToken: Symbol expected at line 1/col 2/char 1 in \usr\htk\training\....\one.wav

ERROR [+7050] HMError:

HMM Def Error: LoadHMMSet: GetToken failed at line 1/col 0/char -1 in \usr\htk\training\....\one.wav

ERROR [+7050] HMError:

ERROR [+2028] Initialise: LoadHMMSet failed

FATAL ERROR - Terminating program ./HCompV

I think this error comes from the HMM prototype file. In fact, I have tried many ways to correct this error but it still stay and I don't know how to correct it. Does anyone have ideas to solve this problem?

here is my HMM prototype file

Hi Thanh,

>I have used the command as in the HTK book (version 3.2.1)

Are you running the most current version of the HTK toolkit (r3.4)?

>I think this error comes from the HMM prototype file.

from the HTK book:

_E has energy
_N absolute energy suppressed
_D has delta coefficients
_A has acceleration coefficients
_C is compressed
_Z has zero mean static coef.
_K has CRC checksum
_O has 0’th cepstral coef

Are you sure you can train using MFCC_D_A feature vectors and   MFCC_0_D_A in your proto?  I'm guessing here, but is it possible that you need the "0’th cepstral coef" in your feature vectors in order to use MFCC_0_D_A in your proto?

You find more info by downloading and searching the HTK mailing list archives (note: you need to be logged in to HTK to download these ...):
