Supertonic 3: High-speed local TTS for 31 languages
Supertonic 3 is a lightning-fast, on-device TTS engine by Supertone that supports 31 languages via ONNX. Its 66M-parameter model claims up to 167x real-time inference on consumer hardware.
Compact 66M parameter footprint makes it ideal for mobile, browser (WASM/WebGPU), and low-power hardware like Raspberry Pi.
- –Expansion from 5 to 31 languages positions it as a robust local alternative to ElevenLabs for developers building global applications.
- –Built-in text normalization accurately handles complex financial and technical notation without the need for custom preprocessing pipelines.
- –Native ONNX support ensures a unified deployment path across Python, C++, Rust, and Swift, simplifying cross-platform integration.
- –Backed by HYBE, the technology is already battle-tested in high-stakes music production and "virtual human" media projects.
