Text::Soundex is good for finding "sound-alike" matches,
but only for English words. If this is the kind of
think you're looking for, you may also want to consider
. It provides similar functionality
to Text::Soundex (reducing a word to a simplified "sound description")
but is more "phonetically" advanced and
can handle phrases, not just single words. Also, neither of
these two as slow at String::Approx, as String::Approx has
to compute the edit distance between two strings and both
Soundex and Metaphone just reduce a string to a "sound description" of it.
Of course, both Metaphone and Soundex are of no use to you
if your data is not English text.
