>>> from g2pw import G2PWConverter
>>> conv = G2PWConverter()
>>> sentence = '上校請技術人員校正FN儀器'
>>> conv(sentence)
[['ㄕㄤ4', 'ㄒㄧㄠ4', 'ㄑㄧㄥ3', 'ㄐㄧ4', 'ㄕㄨ4', 'ㄖㄣ2', 'ㄩㄢ2', 'ㄐㄧㄠ4', 'ㄓㄥ4', None, None, 'ㄧ2', 'ㄑㄧ4']]
>>> sentences = ['銀行', '行動']
>>> conv(sentences)
[['ㄧㄣ2', 'ㄏㄤ2'], ['ㄒㄧㄥ2', 'ㄉㄨㄥ4']]
Load Offline Model
conv = G2PWConverter(model_dir='./G2PWModel-v2-onnx/', model_source='./path-to/bert-base-chinese/')
Support Simplified Chinese and Pinyin
>>> from g2pw import G2PWConverter
>>> conv = G2PWConverter(style='pinyin', enable_non_tradional_chinese=True)
>>> conv('然而,他红了20年以后,他竟退出了大家的视线。')
[['ran2', 'er2', None, 'ta1', 'hong2', 'le5', None, None, 'nian2', 'yi3', 'hou4', None, 'ta1', 'jing4', 'tui4', 'chu1', 'le5', 'da4', 'jia1', 'de5', 'shi4', 'xian4', None]]
Scripts
$ git clone https://github.com/GitYCC/g2pW.git
Train Model
For example, we train models on CPP dataset as follows:
$ bash cpp_dataset/download.sh
$ python scripts/train_g2p_bert.py --config configs/config_cpp.py
Testing
$ python scripts/test_g2p_bert.py \
--config saved_models/CPP_BERT_M_DescWS-Sec-cLin-B_POSw01/config.py \
--checkpoint saved_models/CPP_BERT_M_DescWS-Sec-cLin-B_POSw01/best_accuracy.pth \
--sent_path cpp_dataset/test.sent \
--output_path output_pred.txt
Prediction
$ python scripts/predict_g2p_bert.py \
--config saved_models/CPP_BERT_M_DescWS-Sec-cLin-B_POSw01/config.py \
--checkpoint saved_models/CPP_BERT_M_DescWS-Sec-cLin-B_POSw01/best_accuracy.pth \
--sent_path cpp_dataset/test.sent \
--lb_path cpp_dataset/test.lb
