I've had good luck with Caverphone for a number of speech specific tasks [0]. There is a python implementation directly in the pdf, I also wrote a version here [1], no idea if it exactly matches the pdf version but it worked for my cases. Followups to soundex such as metaphone are encumbered by license issues as far as I know, but Caverphone is free and clear AFAIK. [2] is an insanely great overview of many of these algorithms, be sure to check it out if you are into this stuff.
