NAME

Text::TransMetaphone::ar - Transcribe Arabic words into IPA symbols.

SYNOPSIS

Top

This module is used by Text::TransMetaphone and need not be used directly.

DESCRIPTION

Top

The Text::TransMetaphone::ar module implements the TransMetaphone algorithm for Arabic. The module provides a trans_metaphone function that accepts an Arabic word as an argument and returns a list of keys transcribed into IPA symbols under Arabic orthography rules. The last key of the list is a regular expression that matching all previously returned keys.

A reverse_key function is also provided to convert an IPA symbol key into a regular expression that would phonological sequence under Arabic orthography.

STATUS

Top

The Arabic module applies basic phonetic mappings to generate keys. No more than three keys (including the regex key) are returned at this time. The second key strips the "w" IPA symbol under vowel rules. One key *should* be created for each "w" substitution, this will be fixed in a future release. The module will be updated as more rules of Arabic orthography are learnt.
