(Optional, Only 1.5.2) The soundex
module implements a simple hash
algorithm, which converts words to 6-character strings based on their
English pronunciation.
As of Version 2.0, this module is no longer included.
get_soundex(word)
returns the soundex
string for the given word. Words that sound similar should give the
same soundex
string. sound_similar(word1, word2)
returns
true if the two words have the same soundex
. Example 14-24 uses both functions.
