Double Metaphone creates a key from a word that represents its phonetic properties. Two words with the same Double Metaphone are supposed to sound similar. The Double Metaphone algorithm is an improved version of the Soundex algorithm. @license The Double Metaphone algorithm is copied from the Perl library that holds the following copyright notice. To the best of our knowledge the Perl license is compatible to the SWI-Prolog license schema and therefore including this module poses no additional license conditions. == Copyright 2000, Maurice Aubrey .
