g2pM

This is the official repository of our paper A Neural Grapheme-to-Phoneme Conversion Package for MandarinChinese Based on a New Open Benchmark Dataset (Interspeech 2020).

Install

pip install g2pM

The CPP Dataset

In data folder, there are [train/dev/test].sent files and [train/dev/test].lb files. In *.sent file, each lines corresponds to one sentence and a special symbol ▁ (U+2581) is added to the left and right of polyphonic character. The pronunciation of the corresponding character is at the same line from *.lb file. For each sentence, there could be several polyphonic characters, but we randomly choose only one polyphonic character to annotate.

Requirements

• python >= 3.6
• numpy

Usage

If you want to remove all the digits which denote the tones, set tone=False. Default setting is tone=True.
If you want to split all the non Chinese characters (e.g. digit), set char_split=True. Default setting is char_split=False.

>>> from g2pM import G2pM
>>> model = G2pM()
>>> sentence = "然而，他红了20年以后，他竟退出了大家的视线。"
>>> model(sentence, tone=True, char_split=False)
