Summary

A short demo of Qwen 3.5 Live Translate translating live conversation between English, French and Chinese. It shows speech-to-text translation across 60 languages, speech-to-speech output in 29 languages, low latency from a "readable unit" translation strategy, and hot-word customization so names of people and brands are translated correctly.

Key points

• Qwen 3.5 Live Translate understands and writes 60 languages and speaks 29 of them, which the post says covers 3,500+ language pairs.
• It translates while the speaker is still talking. In the demo, translation starts before the sentence is finished.
• A 'readable unit' translation strategy splits speech into short chunks, so it can translate at very low latency without waiting for full sentences.
• Hot-word customization lets you set up proper nouns (names of people and brands) ahead of time so they translate correctly.
• The demo switches between English, French and Chinese, including sentences that mix languages.
• The demo calls it a big improvement over the previous generation.
