SYNOPSIS

use Lingua::EN::Phoneme;
my $lep = new Lingua::EN::Phoneme();
for ($lep->phoneme('cakes')) { print "$_ is a phoneme"; }
# prints:
#   K is a phoneme
#   EY1 is a phoneme
#   K is a phoneme
#   S is a phoneme
print scalar($lep->phoneme('ale'));
# prints:
#   EY1 L

DESCRIPTION

Lingua::EN::Phoneme provides simple access to the phonemic English data in the Carnegie-Mellon pronouncing dictionary. Unlike Lingua::Phoneme, it does not require a DBI connection to run, or any setup time on the host computer. The data is supplied in a standard Berkeley database, which should be entirely platform-independent.

METHODS

phoneme($latin)

The argument is the representation of an English word in the Latin alphabet. In array context, the method returns a list of the phonemes in the word. Vowels have "0", "1", or "2" suffixes to indicate no, primary, or secondary stress. In scalar context, the method returns the same list joined into a string by single spaces. If the word is not in the dictionary, returns an empty list or undef according to the context.
