Press Alt+L and read what is being said, translated while they speak — YouTube videos, online courses, live streams and podcasts, even when the video has no subtitles.
Three steps, no setup. The translation follows the speaker instead of waiting for the end of the sentence.
Any tab with sound: a YouTube video, a lecture, a webinar, a live stream, a podcast or a news clip.
Live translation starts on that tab. The spoken language is detected for you, or pick it in the panel. Press Alt+L again to stop.
Real-time subtitles on top, the translation below. Click any word in the subtitles to see its meaning.
More than a caption bubble: a live translator built for people who watch and learn in a foreign language.
Long sentences are translated piece by piece as they are spoken, so the translation keeps up with the video.
Two streams in one small panel: what is said, and what it means. Follow the original while you read the translation.
Every word in the subtitles is clickable: translation, word type and meaning, the same popup as double-click translate.
Reads it from the YouTube audio track or the page itself. A dubbed track or another video switches it on the fly.
Install a language pack in Settings and speech in that language is recognized on your own computer, not in the cloud.
Drag the panel anywhere, collapse it to one button, and keep it on screen when the video goes fullscreen.
Live translation listens to the audio of the tab, so it does not need captions to exist:
Most live translation extensions give 5 to 20 free minutes a month, then ask for a subscription. Double Click Translate uses the speech recognition built into Chrome, so a long lecture costs the same as a short clip: nothing.
