NetEase Youdao open-sources Confucius4-R2T2 1.7B real-time streaming ASR model

NetEase Youdao has open-sourced Confucius4-R2T2, a 1.7B parameter real-time streaming ASR model built specifically for voice agents. The architecture combines a single audio encoder with an LLM foundation to handle both offline and streaming speech recognition. It processes speech incrementally while restricting agent actions to committed text to prevent state corruption.
