A Coursera translator for lectures you would rather hear than read

EarDub speaks Coursera lectures in your language, sentence by sentence, in step with the video. Keep your eyes on the slides, the equations and the professor — on any captioned course, including the free ones.

Coursera translates some courses. Most lectures are still subtitles.

Coursera has started dubbing a selection of popular courses with AI, in Spanish, French, Brazilian Portuguese and German. If your course and your language are on that list, use it.

For everything else, what Coursera offers is translated subtitles. A Coursera subtitles translator gives you the same thing: text at the bottom of the screen that you read for the length of the course. In a lecture full of diagrams, code or proofs, reading and watching compete — and the diagram usually loses.

EarDub fills that gap. Any lecture with captions can be heard in Hindi, Arabic, Vietnamese, Indonesian, Japanese, Korean, Chinese and ten other languages, whether or not Coursera has dubbed it.

How to translate Coursera videos with EarDub

Setup takes one click; after that it is one button per lecture.

1
Add EarDub to Chrome and allow it on Coursera
Open Coursera and click the EarDub icon. The first time, Chrome asks whether EarDub may run on coursera.org. Allow it once and EarDub stays off every other site.
2
Open a lecture video and click the EarDub button
EarDub reads the video's captions, rebuilds them into complete sentences and translates them with the subject of the course in mind.
3
Listen while you watch
A natural AI voice speaks each sentence as the professor says it. Keep the original voice underneath, and show bilingual subtitles when you want to check a term.

A Coursera translate extension built for studying

Timed to the lecture

Each sentence is spoken while the professor is saying it, so the voice lines up with the slide on screen. Pause or jump back and the dub follows.

Translated as full sentences

Caption lines are joined into complete sentences before translation, so academic explanations keep their logic and subject terms stay consistent through the course.

The professor is never muted

Separate volume controls keep the original voice available underneath, for names, formulas and terms you want to hear as they were said.

Bilingual subtitles for revision

Show the translation, the original, or both, so the English term you will need for the quiz is always one glance away.

Is the Coursera translator free?

Yes. Every account gets 30 minutes of dubbing a day at no cost, for up to 3 lecture videos a day, with no credit card. All 17 languages and bilingual subtitles are included.

Each lecture video counts as one video. For a full week of a course, Basic ($9.99 a month) covers 60 hours a month and up to 20 lectures a day. Pro ($19.99 a month) has no published time or daily limit.

Only the minutes you actually dub are counted; rewatching a part you already dubbed is free. See all plans.

Which Coursera videos can be translated

The lecture needs captions. Most Coursera lecture videos have English captions; if the player shows no subtitle options, there is nothing to translate.
You need to be signed in and enrolled, so that the lecture video plays for you.
It works in desktop Chrome; Edge and other Chromium browsers generally work too. The Coursera mobile app is not supported.

Coursera translator FAQ

Does the Coursera translator work on free courses?

Yes. If you can play the lecture video and it has captions, EarDub can dub it, whether the course is free or paid.

Is this different from Coursera's own translated subtitles?

Yes. Translated subtitles are text you read. EarDub speaks the lecture in your language, timed to the video, so you can watch the slides and the professor instead of the caption bar.

Which languages can I translate Coursera videos into?

17: English, Spanish, Portuguese, French, German, Italian, Russian, Polish, Turkish, Arabic, Hindi, Indonesian, Vietnamese, Japanese, Korean, and Chinese (Mandarin, Cantonese and Traditional).

Why does Chrome ask for access to coursera.org?

EarDub needs to read the lecture's caption file and add its button to the player, and Chrome asks before any extension can do that on a site. EarDub only asks for coursera.org, and only when you choose to use it there.

Do I need to download the lecture videos?

No. The Coursera translate extension works inside the Coursera player. Nothing is downloaded or uploaded, and your progress on Coursera is tracked as usual.

More answers about quota, troubleshooting and privacy are in thehelp guide. Also see the Udemy translator and the YouTube video translator.
