Overview

Qwen-Audio-3.1-ASR-Flash-Streaming is an end-to-end real-time speech recognition model designed for scenarios such as real-time conferencing, live subtitles, and intelligent interaction. It features low latency and high accuracy in streaming speech transcription. The model supports multilingual and multi-regional Chinese dialect recognition, seamless switching between Chinese and English, hot word and context enhancement, punctuation prediction, and text normalization. It also exhibits strong noise robustness and can adapt to complex acoustic environments. Furthermore, this version supports controllable ASR/AST output for multiple dialects.
