Translate any YouTube video live, even without captions
Not every YouTube video has captions, and automatic ones are not always available in your language. DuoVox listens to the sound your PC plays, so it captions and translates the video as it plays, whether or not it has captions.
How it works
- Install DuoVox from the Microsoft Store and open it.
- Choose the two languages of the conversation. DuoVox detects which one is being spoken.
- Set the audio source to System Audio with the headphone button in the toolbar, then press Start.
- Play the video or live stream in your browser or the YouTube app. DuoVox shows what is said and its translation as you watch.
Why DuoVox for YouTube
- Videos and live streams. Lectures, interviews, news, tutorials and live streams, as they play.
- Both languages at once. The original words and the translation appear side by side, so you can check one against the other.
- Free and offline to start. The Free plan runs entirely on your computer in 30 languages: no account, no internet connection, no time limit.
Free, Standard or Professional
Free captions and translates on your device. Standard and Professional use cloud AI for higher accuracy and more languages — 33 on Standard and 43 on Professional — and include hours every month; Pay-As-You-Go hours never expire. On paid plans, call audio is sent to our AI providers in real time to produce the captions and is not stored by us. See plans and prices.
Good to know
- DuoVox is an assistive tool, not a certified or human interpreter. Automated captions and translations can contain errors, so check anything important.
- Do not rely on it as the only source of meaning in medical, legal, safety-critical or other high-stakes situations.
- DuoVox is available for Windows 10 and Windows 11. It is not yet available in the EU or EEA.
