A video translator extension that speaks the video in your language
EarDub is a free video translator extension for Chrome. It reads a video's captions, translates them into full sentences and speaks them in your language with a natural AI voice, in sync with the picture — on YouTube, online course sites and other pages with a captioned video.
Translate any video with captions, right in your browser
Most ways to translate a video ask you to paste a link somewhere, wait for a new file, and watch it on a different site. EarDub works on the page you already have open: the video stays where it is, and you hear it in your language while it plays.
Nothing is uploaded and nothing is downloaded afterwards. You start the dub from the button in the player, or from the EarDub menu in the Chrome toolbar, and stop it the same way. The original speaker can stay audible underneath at whatever volume you like.
It works in both directions. Translate a video to English when the talk you need was only ever published in Japanese, Korean or Spanish, or translate English videos into Hindi, Vietnamese, Indonesian, Arabic, Portuguese and the other languages EarDub speaks. The source video can be in any language that has captions; you choose the language you want to hear once, and every video after that uses it.
How to translate a video you're watching
Three steps; only the first one happens once.
- 1
Add EarDub to Chrome and choose your language
Install the free extension, sign in, and pick the language you want to hear. It takes about a minute, and the choice applies to every video after that.
- 2
Open the video and click Dub
On YouTube, Udemy and Coursera the Dub button sits at the bottom-right of the player. On any other site, click the EarDub icon in the Chrome toolbar and choose “Dub this video”.

Listen to the video in your language
EarDub reads the captions, translates them into full sentences and speaks them with a natural AI voice, timed to the picture. Click the button again whenever you want the original audio back.
An AI video translator for Chrome that speaks, not just subtitles
A subtitle translator still leaves you reading. A video dubbing extension lets you keep your eyes on the screen — the slides, the code, the demo — and follow the explanation by ear.
Timed to the picture
Each sentence is spoken while the speaker says it. Pause, jump back or skip ahead and the dub follows the video.
Whole sentences, natural phrasing
Caption fragments are joined into complete sentences before translation, so the voice sounds like someone explaining, not a line-by-line machine reading.
60+ natural voices in 17 languages
Hindi, Spanish, Portuguese, Arabic, Indonesian, Vietnamese, Japanese, Korean, Chinese, English and more, with several voices per language.
Original audio and bilingual subtitles
Keep the speaker's real voice underneath, and show the translated and original lines together when you want to check a term.
Translate online course videos, tutorials and talks
People reach for a video translator when the video matters and the language is the only thing in the way. The most common cases:
- Online courses. Lectures on Udemy, Coursera and other course sites, most of them taught in English.
- Tutorials and product demos. Coding, design and software walkthroughs where you need to watch the screen.
- Talks and lectures. Conference talks, university lectures and TED Talks in a language you do not speak.
- Interviews and explainers. Long-form videos that are easier to follow by ear than by reading for an hour.
Works on YouTube, Udemy, Coursera and any site with captions
A Dub button in the player
On YouTube, Udemy and Coursera the button sits at the bottom-right of the player, and on course sites the dub carries on into the next lecture.
Other sites, from the EarDub menu
On sites such as TED, and course sites that use standard video players, click the EarDub icon and choose “Dub this video”. EarDub only runs on a page when you ask it to.
What does not work yet, so you know before installing:
- Videos with no captions at all. EarDub builds the dub from captions and says so when a video has none.
- Some embedded players that run inside a frame from another site, such as Vimeo embeds. A YouTube video embedded on another page can be opened on YouTube in one click.
- Mobile browsers, Firefox and Safari.
Is there a free video translator extension?
Yes. EarDub is free to install, and every account gets 30 minutes of dubbing a day at no cost — up to 3 videos a day, videos up to 60 minutes long, all 17 languages included. You do not enter a card.
Only the minutes you dub are counted. Pausing, seeking or rewatching a part you already dubbed costs nothing extra. Basic ($9.99 a month) covers 60 hours a month; Pro ($19.99 a month) has no published limit. See all plans.
What is the best video translator extension for you?

Video translator extension FAQ
Is there an extension that translates videos?
Yes. Video translator extensions run inside Chrome on the page you are watching. Most of them translate the subtitles; EarDub translates the video's captions and speaks them aloud in your language, so you can watch instead of reading.
Can a Chrome extension translate the audio, not just the subtitles?
Yes. EarDub plays a translated voice in sync with the video and lowers the original audio underneath it. It builds that voice from the video's captions, which is why the result follows the speaker sentence by sentence.
Does the video translator extension work on every website?
It works on YouTube, Udemy and Coursera with a button in the player, and on other sites whose videos have captions from the EarDub menu. Videos with no captions, and videos inside some embedded players such as Vimeo frames, cannot be dubbed yet; EarDub tells you when that is the case.
Can ChatGPT translate a video?
ChatGPT can translate a transcript you paste into it, but it cannot play a translated voice alongside the video while you watch. A video translator extension does that part: it takes the captions from the page and speaks them in your language in time with the picture.
Which browsers does it support?
Desktop Chrome is the supported browser. Edge and other Chromium browsers generally work as well. Firefox, Safari and mobile browsers are not supported yet.
Is my data private?
EarDub only runs on a page when you choose to dub it there. To create the dub, the video's caption text is sent to EarDub's servers for translation and speech; it does not read your browsing history or sell data.
Can I use it to translate my own videos for my channel?
No. EarDub translates videos for the person watching them and produces no file to publish. To add a translated audio track to your own uploads, use a creator dubbing tool or YouTube's automatic dubbing.
