Hello

It looks you are using rather old training scripts, new ones use word_align.pl
instead of sclite. It shoudl work out-of-box without sctk. Please when you ask
about problem learn to provide the versions of the software you are using.

If you still want to run sclite, try to check the logdir for which command is
executed, what is the output. Usually the issue is clearly described in error
message in the logs. Try to run sclite yourself from command line, probably it
will give you more ideas

Sclite should operate on result/db_name.match file and create
result/db_name.align file. Do you have match file? Did you decoder finished
properly. Are there any issues in decoding log in logdir folder?

to nshmyrev:
thanks for your reply, the sphinx trainer that i ' m using was downloaded from
this page: http://www.speech.cs.cmu.edu/sphinx/tutorial.html#traincomponent
i just followed this tutorials.
if i use this line: $DEC_CFG_ALIGN = "builtin"; the WER and SER will be
caculated successfully. i think the word_align.pl will be used, right? but if
i set it tp
$DEC_CFG_ALIGN = "/home/Ian/workspace/sctk2.4.0/bin/sclite";
then the error message:"sclite failed with error code 256 at
scripts_pl/decode/slave.pl line 205" occurred
the decoding was finished and the .match file in the result folder was also
created, however the .align file was not created.
because sclite was not correctly worked. Is there big difference between
sclite 1.4 and sclite 2.4.0, as i have seen in the tutorials the sclite 1.4
was used at CMU. compatibility problem?

This one is outdated. Use http://cmusphinx.sourceforge.net/wiki/tutorialam

. i think the word_align.pl will be used, right?

Yes

I don't think it matters. Probably you just specified the path incorrectly.
Are you sure that binary exists in that path?

Add print in decode script:

    open (OUT, "> $outfile") or die "Can't open $outfile for writing\n";
    my $cmdln = "\"$align\" " .
          "-i rm " .
          "-o sum pralign dtl stdout " .
          "-f 0 " .
          "-r \"$ref\" " .
          "-h \"$hyp\"";
    print ($cmdln);

To print the command executed. Try to execute the command after that from the
command line. You'll easily find the issue.
