At about 99M parameters across the public ONNX assets, Supertonic 3 is much smaller than 0.7B to 2B class open TTS systems. The smaller model size is a practical advantage for download size, startup time, and on-device inference.

## Voice Cloning
This open-weight repository focuses on fixed-voice, local TTS and does not include an official voice-cloning pipeline. If you want to bring your own voice to local Supertonic deployment, [Voice Builder](https://supertonic.supertone.ai/voice-builder) turns a short reference recording into version-specific JSON files for Supertonic 2 and Supertonic 3, so the same custom voice can move with you across supported Supertonic versions.
For a managed creation workflow, [Supertone Play](https://play.supertone.ai/) and the [Supertone API](https://www.supertone.ai/ko/api) provide hosted TTS and voice services with 700+ commercially usable preset voices. You can also listen to Supertonic 3 zero-shot samples on the [official showcase](https://supertonic3.github.io/).
