Need help in speech recognition
===

Good day to all,<br><br>
I'm new in speech recognition and I'm having problems in decoding part.<br>
I followed the steps here http://www.speech.cs.cmu.edu/sphinx/tutorial.html<br>
And when I typed 'perl scripts_pl/decode/slave.pl'<br>
I got these errors.<br><br>
MODULE: DECODE Decoding using models previously trained
        Decoding 130 segments starting at 0 (part 1 of 1) 
Could not find executable for /home/go/Documents/tutorial/an4/bin/sphinx3_decode at /home/go/Documents/tutorial/an4/scripts_pl/decode/../lib/SphinxTrain/Util.pm line 299.

word_align.pl LINE 179<br>
#sub initialize {
    my ($ref_words, $hyp_words, $align_matrix, $backtrace_matrix) = @_;

    # All initial costs along the j axis are insertions
    for (my $j = 0; $j <= @$hyp_words; ++$j) {
	$$align_matrix[0][$j] = $j;
    }
    for (my $j = 0; $j <= @$hyp_words; ++$j) {
	$$backtrace_matrix[0][$j] = INS;
    }
    # All initial costs along the i axis are deletions
    for (my $i = 0; $i <= @$ref_words; ++$i) {
	$$align_matrix[$i][0] = $i;
    }
    for (my $i = 0; $i <= @$ref_words; ++$i) {
	$$backtrace_matrix[$i][0] = DEL;
    }
#}<br><br>

Util.pm LINE 299<br><br>
die "Could not find executable for $cmd" unless -e $cmd;<br><br>

I don't know why but I'm missing the an4-1-1.match file.<br>

Hope you could help me.<br>
Thanks.
