Context-aware AI dubbing, not word-for-word
Most tools translate captions one fragment at a time, so the result sounds machine-made. Our YouTube dubbing extension joins captions into full sentences before translating, and checks every translation.

Read the transcript
- Our ability to learn and get better at tasks through experience is part of being human
- when we are born we know almost nothing and can do almost nothing for ourselves but soon we're learning and becoming more capable every day
- but did you know that computers can do the same.
- Machine learning brings together statistics and computer science to enable computers to learn how to do a given task without being programmed to do so.
- Just as your brain uses experience to improve a task so can computers.
- Say you need a computer that can tell the difference between a picture of a dog and a picture of a cat you could begin by feeding
- it images and telling it this one's a dog, that one's a cat.

Listen to the YouTube video with AI dubbing
The AI voice starts in sync with the picture, with bilingual subtitles.
Dubs YouTube videos and online courses
Built for YouTube. It also dubs Udemy, Coursera and other video sites you allow, and only runs where you ask it to.
Courses behind a login or a paywall work too, unless the video is copy-protected.
Why AI YouTube dubbing beats reading subtitles
Subtitle translators make you read. EarDub reads to you, a full sentence at a time.
Dub YouTube videos without captions
Many videos have no captions. On paid plans, EarDub recognizes the speech in the audio and dubs it anyway.
How dubbing without captions worksTimed to the speaker, sentence by sentence
Each sentence is timed to the speaker's words and plays to the end; speech speeds up slightly (up to 1.45x) to keep pace. Jump anywhere and the voice realigns.
Mix the original audio with the dub
Separate volume sliders for the original sound and the voice. Keep the speaker quietly underneath, or mute the original.
Bilingual subtitles while you listen
Show translated subtitles from 14 to 28 px, or hide them. Reading becomes a choice.
You decide when dubbing starts
Dubbing starts only when you press the button, and EarDub runs only on YouTube and the sites you allow.
Dub YouTube videos into 75 languages
300+ AI voices, male and female, many with regional accents, to match the tone of the video.

YouTube dubbing FAQ
What is EarDub, and how does YouTube dubbing work?
EarDub is a YouTube dubbing extension for Chrome and Edge. It translates a video's captions with AI (or, on paid plans, recognizes the speech when there are none) and plays a natural AI voice in sync with the video. It dubs into 75 languages with 300+ voices, on YouTube and other video sites.
Is EarDub's YouTube dubbing free?
Yes. The free plan dubs 30 minutes a day (180 a month), up to 3 videos of up to 60 minutes each, for videos with captions. Basic ($9.99/month or $83/year) gives 60 hours a month and dubs videos without captions. Pro ($19.99/month or $155/year) has no time limit.
Can EarDub dub a video without captions?
Yes, on the paid plans: EarDub recognizes the speech in the video's audio and dubs it. This works wherever EarDub can read the sound, except copy-protected video (such as Netflix) and live streams.
What's the difference between EarDub and YouTube's auto-dubbing?
YouTube's auto-dubbing appears only on videos whose creators turned it on, in a few languages, with a voice you can't change. EarDub works on almost any YouTube video, in 75 languages with 300+ voices, and only when you turn it on. If a video already offers your language under Settings → Audio track, that's the quickest option.
Does the YouTube dubbing extension work on Android or iPhone?
On Android, yes: install the free Vivaldi browser, which runs Chrome extensions, and add EarDub to dub YouTube on your phone or tablet. iPhone, iPad and the YouTube app aren't supported yet.
Can EarDub translate a YouTube video into English voice?
Yes. Pick English as the dubbing language and EarDub speaks Japanese, Spanish, Korean, Chinese or any other foreign-language video in an English AI voice, in sync with the speaker. English is one of 75 dubbing languages, with 38 voices in 14 accents, including US, UK, Indian and Australian English.
