       Text::Metaphone - A modern soundex.  Phonetic encoding of words.


         use Text::Metaphone;

         # XWRN
         my $phoned_word = Metaphone('Schwern');


       "Metaphone()" is a function whereby a string/word is broken down into a rough
       approximation of its english phonetic pronunciation.  Very similar in concept and purpose
       to soundex, but much more comprehensive in its approach.



           $phoned_word = Metaphone($word, $max_phone_len);

       Takes a word and encodes it according to the Metaphone algorithm.  The algorithm only
       deals with alphabetical characters, all else is ignored.

       If $max_phone_len is provided, Metaphone will only encode up to that many characters for
       each word.

       'sh' is encoded as 'X', 'th' is encoded as '0'.  This can be changed in the metaphone.h
       header file.


       Metaphone algorithm changes

       I have made a few minor changes to the traditional metaphone algorithm found in the books.
       The most significant one is that it will differenciate between SCH and SCHW making the
       former K (As in School) and the latter sh (as in Schwartz and Schwern).

       My changes can be turned off by defining the USE_TRADITIONAL_METAPHONE flag in

       Due to these changes, any users of Metaphone v1.00 or earlier which have stored
       metaphonetic encodings, they should recalculate those with the new version.

       This is the public-domain C version of metaphone from which Binstock & Rex based their
       own..  I haven't actually read it.
