phonemes

I'm aware of SOUNDEX and (double) Metaphone, but these don't let me test for the similarity of words as a whole - for example "Hi" sounds very similar to "Bye", but both of these methods will mark them as completely different.

Are there any libraries in Ruby, or any methods you know of, that are capable of determining the similarity between two words? (Either a boolean is/isn't similar, or numerical 40% similar)

edit: Extra bonus points if there is an easy method to 'drop in' a different dialect or language!
