Everything you need to understand any video
Turn on subtitles, dubbing, or both. Everything works automatically once a video starts.
Translated subtitles
Clear subtitles on the video in your language, or bilingual mode with the original line underneath for learning.
100+ languages
Sinhala, Tamil, Hindi, Bengali, Arabic, Chinese, Spanish and many more, with natural voices even for languages your computer has no voice for.
Smart simplify for fast speech
When a sentence is too long for the gap, the voice speeds up a little or says a shorter version, so the dub never falls behind.
Smooth volume control
The original audio fades down while the dub speaks and comes back between lines. You choose both volumes.

Frequently asked questions
Is YouTube Auto-Dub free?
Yes. YouTube Auto-Dub is free to install and use, with no account or sign-up.
Which languages are supported?
More than 100 languages, including Sinhala, Tamil, Hindi, Bengali, English, Spanish, Arabic, Chinese, French, German and many more.
Does the video need captions?
Yes. The extension translates the video's captions, including YouTube's automatic captions. It switches captions on for you if needed. Videos without any captions cannot be dubbed.
Does it work in Microsoft Edge and Brave?
Yes. It works in Google Chrome and in Chromium-based browsers such as Microsoft Edge and Brave.
Does the extension collect my data?
No. Your settings stay on your device. Only the caption text of the video you are watching is sent to Google Translate to translate it and create the voice. Nothing is sent to the developer. See the privacy policy.
Why does the voice sometimes speak faster or say a shorter sentence?
Some languages take longer to say than the original. To stay in sync, the voice speeds up slightly and, with Smart simplify on, says a shorter version of long sentences. Subtitles always show the full translation.
