On-device TTS with ONNX, interesting but not core.
Supertonic is a 99M-parameter open-weight TTS system running locally via ONNX Runtime across 31 languages, with real-time synthesis at 44.1kHz and expression tags for natural nuance. Its multi-runtime SDKs (Python, Node.js, Rust, etc.) and edge-device readiness enable zero-network, private inference. The latest v1.3.1 adds a local HTTP server with OpenAI-compatible `/v1/audio/speech` endpoints and Voice Builder for custom voice profiles.
Evaluate Supertonic for embedding multilingual, real-time TTS into your agent orchestration or edge applications using its ONNX-based SDKs.
For building AI agents or voice-enabled tools, this provides a lightweight, privacy-preserving TTS that can run on-device without cloud costs, ideal for edge deployments or latency-sensitive pipelines.
