>ERROR [+6510]  LOpen: Unable to open label file test.lab

likeley a path issue - check the paths in your mlf file...  are you following the VoxForge tutorial?

I am clearly following the tutorial. It also creates the output file called 'aligned.out'. But this file is blank. My 'words.mlf' file is the following:

#!MLF!#

.

The aligned.out file is blank with just the first line which is,

#!MLF!#

do you have a "test.lab" label file in your words.mlf file, and do you have a corresponding "test.wav" in your train.scp file?

It might be easier to try it first with the audio files used in the forced alignment tutorial, get that working, then try it with your own files...

Yes I have a speech.lab file in the words.mlf file. And also I have the corresponding speech.wav file in train.scp. There is no .wav file in the tutorial so I cannot use it. I can only listen to the audio from the tutorial but not use it.

I tried with the speech file from the tutorial but its the same error.

This is a path issue.

Do you have *all* the required files in the same directory that you are executing HVite in? i.e.:

aligned.out

dict

hmmdefs

hoe-temp.wav

macros

tiedlist

train.scp

wav_config

words.mlf

Yes, they are all in the same directory and i am running HVite from the same directory. Its just a strange error I got which I cannot figure out.

Thank you

> they are all in the same directory and i am running HVite from the same directory.

could this be a line ending issue on your mlf file (or config file, or some other file...)?

I just downloaded the files and everything seems to work OK - but I am using Fedora 14.

But I tried in both Linux and Windows. Could this be a problem with the new version of HTK? I think this is not line ending issue.

Thank you
