language-model

Use this sub-skill when a task needs ASRT's pinyin-to-Chinese text stage:

• decode a tone-number pinyin token list such as ni3 hao3 ya5 to Chinese text;
• post-process pinyin emitted by an ASRT acoustic model;
• inspect or debug the bundled unigram/bigram language-model counts;
• maintain pinyin_stream_decode state across streaming chunks.

Do not use this sub-skill for audio loading, feature extraction, acoustic pinyin generation, or RPC wrapper design. Route acoustic pinyin generation to the acoustic-models sub-skill, audio and dictionary basics to data-and-features, and HTTP/gRPC endpoint wrappers to serving-clients.

Runtime assets

This sub-skill is self-contained and includes the files required by the ASRT language model:

• dict.txt — tone-number pinyin to candidate Chinese characters;
• language_model/language_model1.txt — unigram character counts;
• language_model/language_model2.txt — bigram character counts;
• scripts/decode_pinyin.py — standalone decoder adapted from ASRT's language-model implementation.

Start here

1. For workflows and model behavior, read references/pinyin-language-model.md.
2. For API signatures and state formats, read references/api-reference.md.
3. For failure diagnosis, read references/troubleshooting.md.
4. For a quick self-contained decode, run:

python scripts/decode_pinyin.py ni3 hao3 ya5

Expected output:
