NetEase Youdao open-sources Confucius4-R2T2, a streaming ASR with 80ms chunks

NetEase Youdao open-sourced Confucius4-R2T2 (Real Real-Time Transcription), a low-latency, high-accuracy streaming ASR model built on Qwen3-ASR. Key traits: configurable decoding chunks from 80ms to 2s, and append-only output that commits transcript text permanently without revising prior words — eliminating flicker in live captioning, LLM agent pipelines and simultaneous translation. The author frames the open question as whether stable, domain-aware streaming recognition becomes standard for voice systems.
