# RUAccent for Core ML

[RUAccent](https://github.com/Den4ikAI/ruaccent)'s Russian stress marks, exported to Core ML for TextSniper
by MacEpic. TextSniper downloads it with Pocket TTS Russian, whose voice reads clearly only with stress marks,
and marks the text on the Mac.

## Contents

From [ruaccent/accentuator](https://huggingface.co/ruaccent/accentuator) (revision `b78ae5ea`), by Denis Petrov
(Den4ikAI), licensed MIT (code) and MIT/Apache 2.0 (weights):

- `homograph.mlpackage`: the homograph network `nn/nn_omograph/tiny2.1` (DistilBERT), fp16.
- `yo.mlpackage`: the ё network `nn/nn_yo_homograph_resolver` (DistilBERT), fp16.
- `accent.mlpackage`: the unknown-words network `nn/nn_accent/big.onnx` (RoFormer), fp32.
- The three vocabularies, `homograph-vocab.txt` with its two added tokens appended.
- `accents.dict`: the stress dictionary `dictionary/accents.json.gz` (3.2 million words) in a compact sorted
  format TextSniper reads through memory mapping.
- `omographs.json`, `yo_words.json` and `yo_homographs.json`: RUAccent's dictionaries, unchanged apart from
  being uncompressed (RUAccent's added "коса" is in `omographs.json`).

From [CMUdict](https://github.com/cmusphinx/cmudict) (commit `74790861`), Carnegie Mellon University's
pronouncing dictionary, licensed BSD-2-Clause (`LICENSE-cmudict`):

- `cmudict.dict`: the first pronunciation of each of its 124,926 words of the letters a to z, sorted by bytes.
  TextSniper writes the Latin words of Russian text in Cyrillic by their English pronunciation, since the Russian
  voice has no Latin letters (`script/pocket/export_cmudict.py`).

Each network was rebuilt in `transformers` from its `config.json` with its ONNX file's weights, converted with
`coremltools` and checked against the ONNX file. `bundle.json` lists every file with its size and SHA-256
(18 files, 55,559,808 bytes).
