I've never had to do such a thing, but I'd suggest simply removing all vowels from the alphabet you use to generate the codes. That way there wouldn't be anything pronouncable. It's certainly a lot simpler than worrying about stop word lists and the attendant worries of missing some foul words in other languages...

Update: At least I hope that no languages have pronounceable words without vowels in the standard ASCII set.
