NAME

Text::TransMetaphone::gu - Transcribe Gujarti words into IPA symbols.

SYNOPSIS

Top

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

DESCRIPTION

Top

The Text::TransMetaphone::gu module implements the TransMetaphone algorithm for Gujarti. The module provides a trans_metaphone function that accepts an Gujarti word as an argument and returns a list of keys transcribed into IPA symbols under Gujarti 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 Gujarti orthography.

STATUS

Top

The Gujarti module is the most developed in the TransMetaphone package. The Gujarti module applies basic phonetic mappings to generate keys. No alternative keys are generated at this time. The module will be updated as more rules of Gujarti orthography are learnt.
