Summary

Boson AI and LMSYS launched the Higgs Audio v3 TTS service based on SGLang-Omni, offering 4 billion parameters and support for 100 languages. The model enables real-time control of emotion, style, and prosody through text tags, and supports streaming synthesis and low-latency inference. This AI and crypto news represents a step forward in integrating on-chain news with advanced voice technology. Developers can now access zero-shot cloning and lightweight computation features.

ME AI announces that Boson AI and LMSYS have jointly launched the Higgs Audio v3 TTS end-to-end service based on the SGLang-Omni inference framework. This model, with approximately 4B parameters, is built on the Qwen3-4B backbone and supports 100 languages (internally evaluated across 111). It achieves word-level WER/CER on zero-shot voice cloning tasks including Seed-TTS, CV3, MiniMax-Multilingual, and Higgs-Multilingual. Developers can dynamically adjust emotion (20+ options), style, prosody (speed/pitch/pauses), and audio effects in real time using in-text control tags. The model supports streaming synthesis, beginning audio generation before the full text is provided while maintaining consistency. SGLang-Omni is specifically designed for multi-stage generation models, unifying autoregressive decoding with lightweight computation to enable low-latency inference. (Source: AiHot)
