First I would start the other way around, look for words in words-only file that match those
with pronunciations. The assumption is that the smaller set is going to be those with pronunciations.
pronunciation-words -> words
instead of
words->pronunciation-words

Next, I think I would look for uniqueness. With a 10Mg file, it is hard to imagine that some
words are not in there more than once. That could reduce the whole thing substantially.
(guess I could be way wrong there... but...

The other thing I might look at if this is not a one-off type thing is using a database if
one is handy.

Otherwise: pumping comparisons into a simple hash like
$words{$word} = $pronunciation does a lot of this for you.

Hope that is somewhat helpful..

...the majority is always wrong, and always the last to know about it...
Insanity: Doing the same thing over and over again and expecting different results.
