wolfgitpr/cpp-pinyin: A lightweight Chinese/Cantonese to Pinyin library.

cpp-pinyin is a lightweight Chinese/Cantonese to Pinyin library.

Chinese dialects can be used to create their own dictionaries using makedict.

Initial version algorithm reference zh_CN, and undergo significant optimization.

pinyin-makedict is the tool for creating custom dialect dictionaries.

• Interface reference pypinyin

• Only Unicode within the range of [ 0x4E00 - 0x9FFF ] is supported.

• Segmentation for heteronym words.

• Support Traditional and Simplified Chinese.

• Speed is very fast, about 1,000,000 words/s on Intel i3-8100.

• Achieved an accuracy rate of 99.95% on a 200000 word Lyrics-Pinyin test set Without-Tone.

• The With-Tone test on CPP_Dataset(about 79k sentences) achieved an accuracy of 90.3%, while the accuracy of pypinyin was approximately 87%.
