# Supertonic 3 (mirror) — for the arraypress speech tools

An **unmodified** mirror of [Supertone/supertonic-3](https://huggingface.co/Supertone/supertonic-3)
at commit `3cadd1ee6394adea1bd021217a0e650ede09a323`: the six ONNX/JSON files of the
pipeline (duration predictor, text encoder, vector estimator, vocoder, tokenizer config,
unicode indexer) and the ten voice styles (F1–F5, M1–M5), ~410 MB. It exists so the fleet's
`swift-tts` (and the `speak` / `redub` tools on it) download from a repository pinned and
controlled by the same people as the tools, rather than following another repo's `main`.

Every file matches the hash Supertone publishes (SHA-256 for the large files, git blob
SHA-1 for the small ones). For the model itself — what it is, quality, languages — see
[Supertone's model card](https://huggingface.co/Supertone/supertonic-3).
