[SOLVED] Isolated Digit Recognition using HTK

Isolated Digit Recognition using HTK

I am experimenting isolated word recognition using HTK. So far I've built these files:

dict file:

eight           eight sp
five            five sp
four            four sp
nine            nine sp
one             one sp
sent-end        sil sp
sent-start      sil sp
seven           seven sp
six             six sp
three           three sp
two             two sp
zero            zero sp

source.mlf file:

#!MLF!#
"*/00F1SET0.lab"
zero
.
"*/01F1SET0.lab"
one
.
"*/02F1SET0.lab"
two
.
"*/03F1SET0.lab"
three
.
"*/04F1SET0.lab"
four
.
"*/05F1SET0.lab"
five
.
"*/06F1SET0.lab"
six
.
"*/07F1SET0.lab"
seven
.
"*/08F1SET0.lab"
eight
.
"*/09F1SET0.lab"
nine
.

And I keep the 0*F1SET0.wav files inside wav directory of the project directory.

And mhphones0.led with following commands:

EX
IS sil sil
DE sp

Then I am trying to execute this command:

HLEd -l '*' -d dict -i models0.mlf mkphones0.led source.mlf

But it is showing this error:

  ERROR [+1230]  ReadLabId: string arg expected at line 3/col 6/char 21 in mkphones0.led
 FATAL ERROR - Terminating program HLEd

I don't understand what's the problem in the commands of mkphones0.mlf file. Please help and thanks in advance!

Solution

Well, at last I solve this problem by putting a newline at the end of mkphones0.led and adding (etc.) at the end of source.mlf. Thanks @Nikolay Shmyrev for pointing about the newline.
