What is Qwen3-LiveTranslate？
Qwen3-LiveTranslate is a multilingual real-time audio-video simultaneous translation model developed by Alibaba Tongyi, based on large language model technology. The model supports translation in 18 languages and multiple dialects, and features vision-enhanced capabilities that leverage lip movements, gestures, and other multimodal information to improve translation accuracy. With low latency (as low as 3 seconds) and lossless simultaneous translation technology, it ensures translation quality close to offline translation, accompanied by natural-sounding voices. The model performs exceptionally well in complex acoustic environments, bridging language barriers and making communication smoother and more natural.
Key Features of Qwen3-LiveTranslate
-
Multilingual Real-Time Translation: Supports 18 languages (e.g., Chinese, English, French, German, Japanese, Korean, etc.) and multiple dialects (e.g., Mandarin, Cantonese, Sichuanese) for both offline and real-time audio-video translation.
-
Vision-Enhanced Translation: Integrates visual context such as lip movements, gestures, and text to improve translation accuracy in noisy environments or when words have multiple meanings.
-
Low-Latency Simultaneous Translation: Achieves a simultaneous translation experience with a minimum of 3 seconds latency using a lightweight mixture-of-experts architecture and dynamic sampling strategy.
-
Lossless Translation Quality: Semantic unit prediction technology mitigates cross-language word order issues, ensuring translation quality comparable to offline translation.
-
Natural Voice Output: Adapts tone and expressiveness based on the original speech content to generate human-like audio.
