What is Supertonic?
Supertonic is a high-performance, open-source text-to-speech (TTS) system released by Supertone. Designed for extreme speed and lightweight deployment, it contains only 66M parameters yet can generate speech at up to 167× real-time, making it one of the fastest TTS systems available. Supertonic runs entirely offline with all processing done locally, ensuring full privacy and zero latency. It supports multiple languages and can seamlessly process complex text such as numbers, dates, currency, and abbreviations without any preprocessing. Highly configurable, it allows users to adjust inference steps, batch size, and other parameters as needed. With support for Python, Node.js, Java, and more, Supertonic is suitable for offline readers, real-time game dubbing, smart speakers, and many other applications.
