This subject has come up before.

My pure perl approach is explained in Re: Fuzzy Searching: Optimizing Algorithm Selection and there is a greatly improved performance version at Re^2: Fuzzy Searching: Optimizing Algorithm ( A few improvements)..

Also of note is ysth & demerphq's compiled XS trie approach the code for which can be found in this Algorithm Showdown: Fuzzy Matching.

Be warned: Both these threads contain ultimately futile, heated technical debate.

I still have, several further iterations of performance improvement of my code kicking around. If you are seriously interested and want to try and take it forward, I could look them out.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
