Metaphone is an approvement of Soundex. The built in php function use the original algorithm from 1990. The are to further improvement since 1990. The Double Metaphone, you can use the as PECL extension from http://pecl.php.net/package/doublemetaphone or download the class file from http://swoodbridge.com/DoubleMetaPhone/.
