Grapheme-to-Phoneme transformations that preserve input and output indices!

This library is for handling arbitrary conversions between input and output segments while preserving indices.

Background

The initial version of this package was developed by Patrick Littell and was developed in order to allow for g2p from community orthographies to IPA and back again in ReadAlong-Studio. We decided to then pull out the g2p mechanism from Convertextract which allows transducer relations to be declared in CSV files, and turn it into its own library - here it is!

Install

The best thing to do is install with pip pip install g2p.

Otherwise, clone the repo and pip install it locally.

$ git clone https://github.com/roedoejet/g2p.git
$ cd g2p
$ pip install -e .

Usage

The easiest way to create a transducer is to use the g2p.make_g2p function.

To use it, first import the function:

from g2p import make_g2p

Then, call it with an argument for in_lang and out_lang. Both must be strings equal to the name of a particular mapping.

>>> transducer = make_g2p('dan', 'eng-arpabet')
>>> transducer('hej').output_string
'HH EH Y'

There must be a valid path between the in_lang and out_lang in order for this to work. If you've edited a mapping or added a custom mapping, you must update g2p to include it: g2p update

CLI

update

If you edit or add new mappings to the g2p.mappings.langs folder, you need to update g2p. You do this by running g2p update

convert

If you want to convert a string on the command line, you can use g2p convert <input_text> <in_lang> <out_lang>

Ex. g2p convert hej dan eng-arpabet would produce HH EH Y

generate-mapping

If your language has a mapping to IPA and you want to generate a mapping between that and the English IPA mapping, you can use g2p generate-mapping <in_lang> --ipa

Ex. g2p generate-mapping dan --ipa will produce a mapping from dan-ipa to eng-ipa. You must run g2p update afterwards to update g2p. The resulting mapping will be added to the folder in g2p.mappings.langs.generated

Studio

You can also run the g2p Studio which is a web interface for creating custom lookup tables to be used with g2p. To run the g2p Studio either visit https://g2p-studio.herokuapp.com/ or run it locally using python run_studio.py.

Alternatively, you can run the app from the command line: g2p run.
