8.145 Text::Soundex

Implements the soundex algorithm, which hashes a word (in particular, a surname) into a compressed form that approximates the sound of the word when spoken by an English speaker.

use Text::Soundex;

$code = soundex $string;  # get soundex code for a string
@codes = soundex @list;   # get list of codes for list of strings
Returns the value of the variable $soundex_nocode if there is no soundex code representation for a string. $soundex_nocode is initially set to undef, but can be reset to another value, e.g.:
$soundex_nocode = 'Z000';
