It is based primarily on the original Metaphone algorithm but contains some of the pronunciation exceptions from DoubleMetaphone. It's similar to soundex in purpose, but as it knows the basic Metaphone SupportThese functions provide a means to implement Double Metaphone or Metaphone 3 phonetic encoding or fuzzy-match algorithms which return a primary code, a secondary code, or both for a given string. language. The levenshtein method mentioned computes the Levenshtein distance between two strings fed as parameters. There are quite a few different uses for phonetic comparison algorithms including: Spell checkers can often contain phonetic algorithms.
