NAME

Telephone::Mnemonic::US - Maps US telephone numbers from mnemonic 'easy-to-remember' words to digits, it can also attempts the reverse and maps telephone digits to mnemonic words.

printthem Input: the output of to_words (a href) Output: displays some of the data in a table

printvalids Helper function for printthem() Input: the hash ref Output: a stings

to_words Input: a string, like '703-111-2628', and an optional search timeout Output: sorted set of dictionary words that correspond to the tel number substrings

to_num Translates a mnemonic tel number to digits Input: an alphanumeric sting, like '(g03) verison' Output: a string like, like '(703) 232 3333'

SYNOPSIS

 use Telephone::Mnemonic::US    qw/ to_words to_num /;
 to_words('(263) 748 7233');           => ameritrade   assuming it was n the dictionary
 to_words('(263) 748 7233',9);         => ameritrade   but might timeout after 9 sec of searching
 to_num('ameritrade') ;                => (263) 748 7233  

DESCRIPTION

Converting Mnemonics to Digits

The to_num function converts (a well formed ) telephone mnemonic to digits, returns undef on failure. A well formed US number must be something reasonable, it should contain either 7, or 10 digits. You can supply it in many format,i.g. 703.verison, verison, gotverison, or got-ver-ison. On success, you receive a string such as '(703) 123 4567'

Converting Digits to Mnemonics

The to_words function converts (a well formatted) telephone number to one or more mnemonics. Unless you lucky to receive one dictionary word that maps to a 10-digit number, as partial match, you will probably receive several answers, with each answer matching one or two dictionary words. If you requested a match for telephone number '(703) 404 2628', some answers are bound to include the words 'boat', 'coat', and 'anat' as partial match for the last 4 digits. An optional parameter can serve as search timeout. On success it returns a hash reference containing all possible answers or partial segments; you could also use the printthem function to display them.

It understands telephone numbers in many formants; numbers without area code or with mixture of letters and digits are possible but it is best to stick with the formats supported by Number::Phone .

The Dictionary must be located at /usr/share/dict/words or at /usr/dict/words with words in dictionary order.

EXPORT

None by default.
