Coursera Video Translator hear every lecture in your language.
DubTab is a Coursera translate extension that works in real time: an AI voice dubs the instructor in your language while translated captions follow on screen. Use either, or both — on any course, on any plan.
Free 15-minute trial · No credit card · Works on audit courses and Coursera Plus
Lectures in your language — not just the menus.
You switched the course to your language — the readings, quizzes and menus changed, but the instructor in the video still speaks English.
With subtitles alone, your eyes bounce between the code on the slide and the text at the bottom of the screen. A one-hour module takes two.
Your language isn't on Coursera's list, or your course isn't one of the 100+ it dubbed — so you're back to the English transcript and a dictionary.
Listen in your language, with translated captions on screen when you want to read along.
Keep your eyes on the slides and the code while the AI voice carries the lecture — captions stay one click away whenever you want them.
Auto catch-up keeps the dub in sync with the video, so the voice never drifts behind the instructor.

Built for studying, not just translating
Real-time AI dubbing
The voice speaks while the video plays — not a file you upload and wait for.
Bilingual captions
Translated captions alongside the original English, or your language alone. Read along with the dub, or use captions on their own — both follow the lecture live.
Stays in sync automatically
Auto catch-up keeps the dub aligned with the video, so the voice never lags behind the instructor.
Any source language, auto-detected
A course taught in French, Spanish or any other language works the same way — DubTab listens to the audio and detects the language itself.
Lectures, labs and readings with video
Anything that plays in the Coursera tab gets dubbed the same way — lecture videos, labs, and readings that include a video.
Windows desktop app included
Dub anything beyond the browser — local videos, meetings, any app's audio.
What people learn on Coursera with DubTab
Most Coursera courses are taught in English. A lot of the people taking them don't think in English.
Professional Certificates in IT, data and marketing
Entry-level certificate programs from big tech companies and universities — follow every module in your language, from the welcome video to the final project.
AI and machine learning
From the classic intro to machine learning to deep learning and LLM app courses — hear the intuition and the math explained in your language, as it's taught.
Cybersecurity and IT support
Networking, security fundamentals and career-prep courses — technical vocabulary is hard enough in one language; let the dub carry it in yours.
Business, project management and Scrum
Project management, compliance, bookkeeping and agile courses — keep up with the frameworks while you take notes.
University courses in the humanities and sciences
Philosophy, public health, economics, learning how to learn — the lecture-hall experience, in your language.
Courses taught in another language
A French university course or a Spanish-language specialization — DubTab detects the spoken language and dubs it into yours, so the catalog stops being sorted by language.
Doesn't Coursera translate courses itself?
Partly — and when it has what you need, use it. Coursera has translated the text of 5,000+ courses into 25 languages, and dubbed the video of 100+ courses into four. Everything outside that is still an English-speaking instructor with an English transcript — and that's where DubTab comes in.
| What you're watching | What Coursera gives you | DubTab |
|---|---|---|
| One of the 100+ AI-dubbed courses, in Spanish, French, German or Portuguese | Dubbed audio in the instructor's own voice — use it | ✓ Adds the other 60+ languages, and bilingual captions if you want them |
| A translated course (5,000+ courses, 25 languages) | Subtitles, readings and quizzes translated — the audio stays English | ✓ Real-time dub in your language, plus captions |
| Any other course in the 10,000+ catalog, or a language not on Coursera's list | English subtitles, or whatever the partner provided | ✓ Real-time dub + captions, 60+ languages |
| A course taught in French, Spanish or another language | Subtitles in that language, if provided | ✓ Detects the spoken language, dubs it into yours |
Coursera translated the text. The instructor still speaks English.
Switch a course to your language and the readings, quizzes and menus follow — but the lecture video is the same recording, with your language as subtitles. DubTab is the missing half: it translates the instructor's voice itself, live, so the translated course finally sounds translated too.
AI dubbing covers 100+ courses in four languages. The catalog has 10,000+.
Coursera's own dubbing is excellent where it exists: the instructor's voice, lip-synced, in Spanish, French, German or Brazilian Portuguese. Open the player's settings and check the Audio menu — if your language is there, use it. If it isn't, DubTab dubs the course in real time, in 60+ languages, on the same tab.
Your language isn't on Coursera's list?
Coursera's dubbing speaks four languages, and its text translations cover about 25 — each course page shows how many it has. Arabic, Vietnamese, Hindi, Tamil, Bengali, Japanese: none of them has a dubbed course, and several aren't on the translation list at all. DubTab doesn't work from a list. It listens to the audio and speaks your language, on every course.
