Is this really what the OP was asking for. If I understand it correctly,
Levenshtein distance works out the number of edits required to transform
the string to the target string. The smaller the more equivalent, but with
the OP's problem I would expect


table1      table2
brian       briam
            erian


I think the OP would like to guess at 'briam' rather than 'erian', but
Levenstein would rate them equally good guesses?

I know this is pushing it more toward phonetic alaysis of the words or
something similar, and thats orders of magnitude more complex.

just in case,

might be a good place to start looking into it, along with the NLTK
libraries here
