NetEase-Youdao releases Confucius4-R2T2, a true-streaming ASR model for live captions, simultaneous translation, and voice agents. 🤖 🏆 R2T2 achieves SOTA latency and recognition quality among the evaluated open-source models, while remaining competitive with leading closed-source systems. ⚡ Configurable 80ms–2s chunks deliver 200–600ms average latency with near-offline recognition accuracy. 📝 Append-only decoding commits stable text without revising earlier words, avoiding transcript flicker and giving downstream agents reliable input. 🌍 Optimized for Chinese and English, with multilingual recognition, hotword prompts, and contextual prompts. 🧰 The GitHub repo includes inference code, a minimal example, and a vLLM backend for both offline and real-time streaming ASR. 📜 Code: Apache 2.0.
