g2pW for Cantonese

A Cantonese Grapheme-to-Phoneme (G2P) conversion tool, adapted from the original g2pW repository for Chinese Mandarin.

Overview

This is a Cantonese adaptation of the g2pW repository, designed for polyphone disambiguation in Cantonese. The model converts Chinese characters (graphemes) to Jyutping (phonemes).

Model

The trained model is available at:
https://huggingface.co/Naozumi0512/g2pW-Cantonese

Usage

git clone https://github.com/Naozumi520/g2pW-Cantonese && cd g2pW-Cantonese
git clone https://huggingface.co/hon9kon9ize/bert-large-cantonese
git clone https://huggingface.co/Naozumi0512/g2pW-Cantonese G2PWModel-v2-onnx
pip install -r requirements.txt

from g2pw import G2PWConverter

conv = G2PWConverter(model_dir='./G2PWModel-v2-onnx/', model_source='./bert-large-cantonese/', use_cuda=True)
# "校":
sentence = '調校溫度'
print(conv(sentence)) # [['tiu4', 'gaau3', 'wan1', 'dou6']]
sentence_1 = '校服'
print(conv(sentence_1)) # [['haau6', 'fuk6']]

Data Sources

This model was trained on data collected from:

• Rime Cantonese Input Schema (jyut6ping3.dict.yaml)
