What arrives on demand

dictionary
Hunspell dictionary with full affix morphology and compounding
frequency
No Kelly list under this code; ranking leans on the dictionary and model
semantic
FastText ONNX embedding model for context-aware reranking — available as fluency (~15 MB, the default), full (120 MB), or mini (~3 MB), chosen at setup
keyboard
Keyboard proximity on the Vietnamese-QWERTY layout

Automatic detection is included — a document in this language is found before it is checked.

Set it up

gem install kotoshu
kotoshu setup vi

# optional, for semantic reranking
gem install onnxruntime
kotoshu setup vi --model                  # fluency, the default (~15 MB)
kotoshu setup vi --model --tier full      # maximum accuracy (~120 MB)

Notes

  1. 1.

    Keyboard-proximity suggestions use the Vietnamese-QWERTY grid, where tone and vowel marks are typed as dead keys over ASCII letters.

  2. 2.

    The fastText ONNX model fasttext.vi.onnx is available for semantic reranking of suggestions.

  3. 3.

    Vietnamese ships a single base dictionary; no regional variants are staged yet.

  4. 4.

    No Kelly frequency list is published for Vietnamese yet; frequency data is an optional resource, so checking works without it.
