aigclink · x · 2026-09-20
NetEase Youdao has open-sourced Confucius4-R2T2, a low-latency, high-accuracy true streaming ASR model.
- Real-time, append-only: fine-grained decoding chunks configurable from 80ms to 2s; committed transcript text is never revised, avoiding flickering in live captioning.
- Use cases: live subtitling, simultaneous speech translation, voice customer service, and downstream NLP pipelines or LLM agents that must act on text instantly.
- Repo: ships with example.py, WebSocket server/client scripts, and bilingual docs for quick deployment.
