Qwen3.8-LiveTranslate

Simultaneous interpretation built on an interleave architecture with a hybrid mixture-of-experts backbone split into Thinker and Talker modules. It recognises 60 source languages and speaks 29 of them, does per-speaker diarisation with individual voice cloning in real time, and cuts average lagging from 2.8 seconds in the Qwen3.5 predecessor to 2.3. Released 19 September through Alibaba Model Studio with a trial endpoint. Note that qwen.ai renders as an empty JavaScript shell to automated fetches, so these figures come from Qwen's own announcement and secondary coverage rather than the page itself.
