If I understand your question correctly, the following code should translate certain Spanish words into numerical values: 
#!/usr/bin/env perl

use warnings;
use strict;

my %table = (
    barra   => '/',
    cero    => 0,
    uno     => 1,
    dos     => 2,
    tres    => 3,
    cuatro  => 4,
    cinco   => 5,
    seis    => 6,
    siete   => 7,
    ocho    => 8,
    nueve   => 9
);

while (<DATA>) {
    if (/##(.*)##/) {
        my @words = split /\s+/, $1;
        my $pre = $`;
        my $post = $';
        for (@words) {
            for my $key (keys %table) {
                if ($_ eq $key) {$_ = $table{$key}}
            }
        }
        print "$pre##", "@words", "##$post";
    }
    else {
        print;
    }
}

This may not be the most efficient way to do this, considering that you have large files, but our fellow Monks will no doubt be able to help you optimize this.
