NAME

Text::DoubleMetaphone - Phonetic encoding of words.

SYNOPSIS

  use Text::DoubleMetaphone qw( double_metaphone );
  my($code1, $code2) = double_metaphone("Aubrey");   

DESCRIPTION

This module implements a "sounds like" algorithm developed by Lawrence Philips which he published in the June, 2000 issue of C/C++ Users Journal. Double Metaphone is an improved version of Philips' original Metaphone algorithm.

In contrast to the Soundex and Metaphone algorithms, Double Metaphone will sometimes return two encodings for words that can be plausibly pronounced multiple ways.

For additional details, see Philips' discussion of the algorithm at:

FUNCTIONS

double_metaphone( STRING )

Takes a word and returns a phonetic encoding. In an array context, it returns one or two phonetic encodings for the word. In a scalar context, it returns the first encoding. The first encoding is usually based on the most commonly heard U.S. pronounciation of the word.
