High-quality Text-to-Speech, on your device. phonon-31m is a text-to-speech model from the Phonon family. It turns text into natural 24 kHz speech in English. It streams audio while it is still generating, and it is small enough to run in a browser tab, on a phone, or on a laptop CPU. Phonon builds on Pocket TTS and the Mimi codec, developed by Kyutai. Try it in your browser · All Phonon models · Runtime on GitHub · Python · Browser · Discord All of them run on the same runtime and use the same file layout, so switching models means changing the repo ID. Every runtime names this model as hf://gradium/phonon-31m-en, and takes lang, which selects how text is normalized (numbers, symbols, dates). This model speaks English, so use en. uvx runs the Python package's command without installing it. The standalone ptts binary from GitHub Releases or Homebrew (brew install…

Compatibility and lineage
Reported languages: en
Base-model lineage was not included.
Parameter count is not a RAM/VRAM requirement. Check precision, quantization, context length and runtime compatibility in the model card; no hardware or API-cost claim is inferred here.
Use and evaluate
Check license terms and access requirements first. Review the model card’s documented loading instructions, evaluations and safety limitations. Benchmark scores are not imported by this directory, and popularity is not an accuracy ranking.
No model weights are downloaded or executed by AltAPIs. Never enable remote model code without reviewing it.
