Supertonic - an open-source AI text-to-speech system that enables ultra-fast, completely offline text synthesis.

What is Supertonic?

Supertonic is Supertone's open-source, high-performance text-to-speech (TTS) system, boasting exceptional speed and lightweight design. Containing only 66M parameters, it generates speech up to 167 times faster than real-time, making it one of the fastest TTS systems available. Supertonic runs entirely offline, with all processing completed locally on the device, ensuring privacy and zero latency. It supports multiple languages and can seamlessly handle complex text such as numbers, dates, and currencies without preprocessing. Supertonic is highly configurable, allowing users to adjust parameters such as inference steps and batch processing as needed. It supports multiple development environments including Python, Node.js, and Java, making it suitable for various scenarios such as offline readers, real-time game voice-over, and smart speakers.
