Setup, troubleshooting, billing, and everything about dubbing YouTube videos into your language.
Last updated:
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.
Yes: it dubs recorded videos while you watch, in step with the picture. Some tools translate by listening to the video as it plays, so their voice can only start after the speaker has finished and trails the picture, often by a whole sentence, most of all on videos without captions. EarDub prepares each sentence before it is said, from the captions' timing or, when there are none, by recognizing the audio the player has already loaded ahead of you, so each dubbed sentence can start when the speaker starts. There's nothing to upload and no waiting for the whole video to process: the dub starts within seconds, keeps generating just ahead of where you are watching, and pauses when you pause. After you jump to a new point, the first sentence there takes a few seconds to prepare. It's built for recorded videos, not live streams. How the two approaches differ: Three ways dubbing tools work.
On Google Chrome, install EarDub from the Chrome Web Store with the "Add to Chrome" button; on Microsoft Edge, install it from the Edge Add-ons store. Then open or refresh any YouTube tab. EarDub officially supports desktop Chrome and Edge, and other Chromium browsers such as Brave install it from the Chrome Web Store. Dubbing requires a free account: sign in with Google, Microsoft or your email address.
Open a YouTube video, then click the EarDub button in the player's control bar (next to the settings gear). The first dub takes a moment to generate: captions are extracted, translated, and converted to speech. Choose your dubbing language and voice in the extension popup before or after clicking.
75 languages, including English, Spanish, Portuguese, French, German, Russian, Turkish, Arabic, Hindi, Indonesian, Vietnamese, Thai, Japanese, Korean, Mandarin and Cantonese, with 300+ voices and regional accents. Source videos can be in any spoken language.
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.
Yes. EarDub dubs Udemy and Coursera lectures in the same 75 languages as YouTube. Allow the site once from the EarDub menu; after that, start the dub from the button on the player and it carries on into the next lecture of the course. You need to be signed in and enrolled so the lecture plays for you. On Coursera the lecture needs captions; on Udemy, lectures without captions are dubbed too on the Basic and Pro plans.
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.
EarDub uses neural text-to-speech voices, the same class of voices used by professional narration tools, not the robotic system voices older extensions rely on. Each language offers multiple voices with different tones. If a voice does not fit the video, switch to another one in the extension popup; the change applies to the next sentences immediately.
EarDub translates whole sentences with the context of the whole video: it reviews the captions first, keeps a glossary so recurring terms stay consistent, and renders idioms by meaning rather than word for word. No machine translation is perfect; wrong captions or unclear speech can still cause mistakes, and bilingual subtitles let you check a line against the original. This is the same on every plan, including Free.
Open the extension popup and use the two volume sliders: one controls the original video's soundtrack, the other controls the dub. Lower the original to around 10 to 30 percent to keep the speaker's energy in the background, or set it to 0 to hear only the dub. Both settings are remembered for future videos.
Dubbing follows the video's word-level timestamps, and a sentence that starts always plays to the end: EarDub never cuts speech mid-word. When a translated sentence runs longer than the original, playback speeds up gently (up to 1.45x) to catch up. If you drag the progress bar, the dub re-aligns to the new position automatically.
Not yet. YouTube captions do not contain speaker identity, so EarDub cannot tell who is talking and uses your selected voice for everyone. This is a limitation of all caption-based dubbing tools. Distinguishing speakers requires audio-level analysis, which is on our research roadmap but not promised for a specific date.
Yes at normal speeds. The dub follows the video timeline, so 1x to 1.25x works well. At higher speeds the translated speech may not physically fit into each sentence's time window, so some sentences can be skipped to keep up; a sentence that does play is never cut off. For dubbed viewing we recommend staying at 1.5x or below.
Work through this list, which resolves most reports: 1. Refresh the YouTube tab (always needed right after installing). 2. Check whether the video has captions (the CC button in the player): videos without captions are dubbed on the paid plans (Basic and Pro) only; on the free plan you'll see an upgrade prompt instead. 3. Check in the extension popup whether today's free minutes are used up. 4. Update Chrome to the latest version and make sure EarDub is enabled in chrome://extensions. 5. If it still fails, send us the video URL via the feedback page; that lets us reproduce the exact problem.
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.
| Site | Videos with captions | Videos without captions |
|---|---|---|
| YouTube | All plans | Paid plans |
| X | All plans | Paid plans |
| Bilibili | All plans | Paid plans |
| Gumroad | All plans | Paid plans |
| Udemy | All plans | Paid plans |
| Coursera | All plans | Not supported |
| Other sites ("Dub this video") | All plans | Paid plans |
On Bilibili, sign in so EarDub can read a video's subtitles (the uploader's or Bilibili's AI ones). Desktop Chrome and Edge. On Android (Vivaldi), YouTube videos with captions only. Live streams, videos with copy-protected audio (such as Netflix) and some embedded players aren't supported.
Generation time grows with video length: a 10-minute video typically takes well under a minute, while a 2-hour video takes several. If it seems frozen: refresh the tab and click the button again (already-generated audio is reused, so you lose nothing), check your network or VPN stability, and confirm your daily or monthly allowance is not exhausted. If one specific video always hangs, send us its URL.
No meaningful impact in normal use. The heavy work (speech recognition, translation and speech generation) happens on EarDub's servers, not in your browser; the extension only plays the finished audio and draws subtitles. It loads only on YouTube, the sites you allow (Udemy, Coursera, X, Bilibili, Gumroad) and pages you choose to dub, and stays completely idle everywhere else.
No. The extension runs on youtube.com, on udemy.com, coursera.org, x.com, bilibili.com and gumroad.com if you allow them, and on any other page only when you click to dub a video there, so it cannot read, modify, or slow down sites you have not chosen. This is enforced by Chrome's permission system, not just by our code: you can check and change EarDub's site access yourself in chrome://extensions under EarDub's details.
On the free plan, videos need captions (auto-generated ones work); Basic and Pro also dub videos without captions on most sites. Videos with copy-protected audio (such as Netflix) and live streams can't be dubbed, and some embedded players don't work yet. Everyone in a video shares one voice. Captions don't say who is speaking, so a conversation between several people is read by the voice you picked. On phones, EarDub works only in the Vivaldi browser on Android. iPhone, iPad and the YouTube app aren't supported.
Yes. Dubbing requires a free account: sign in with Google, Microsoft or your email address. Signing in lets us track your plan usage, sync it across devices, and manage paid subscriptions. No password is needed: Google and Microsoft take one click, and email sends you a sign-in link.
The free allowance resets at the start of each UTC day and includes 30 dubbing minutes and 3 videos. Usage is measured by newly dubbed playback progress, so pausing or replaying an already-dubbed section does not consume it again. Basic includes 60 hours per calendar month and 20 videos per day. Pro has no published time, video-length, or daily-video limit.
You can cancel anytime from this site under "Manage subscription" — self-serve, no emails or chats required — and it takes effect at the end of your current paid period, with no immediate cutoff. Payments are processed securely by Stripe (some subscriptions and WeChat Pay passes, mainly earlier ones, are billed by Waffo); if you have any question about a charge, contact us and we'll look into it. The free plan never requires payment details.
To generate a dub, the video's caption text and title are sent to our servers for translation and speech synthesis (for a video without captions, its audio is sent instead, in short pieces, for speech recognition, and is not stored), and the resulting audio is cached so repeat views are instant. EarDub doesn't look at the other pages you visit. It receives the title and address of the videos you dub, and usage events of its own buttons, to run and improve the service. It does not sell data. Settings like voice and volume are stored locally in your browser.
Yes, in three ways. First, some videos include extra audio tracks: click the settings gear, then "Audio track". Second, subtitles: enable captions and pick an auto-translated language. Third, a dubbing extension like EarDub, which speaks the translation aloud in sync and works on almost any YouTube video (with captions on every plan, and without captions on Basic and Pro), even when the first two options are missing.
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.
YouTube rolled out automatic AI dubbing and now enables it by default on many channels, so the platform may auto-select a dubbed track based on your language settings. Many viewers find the default voice robotic. To get the original audio back, open the player's settings gear, choose "Audio track", and select the original language.
Per video: click the settings gear in the player, open "Audio track", and choose the original language track. As of mid-2026 YouTube offers no reliable account-wide switch to disable auto-dubbing everywhere, which is a common complaint. If you want dubbing only when you ask for it, with a voice you choose, that is exactly the control EarDub gives you.
YouTube's official auto-dubbing only exists where the creator's channel has the feature enabled, the language pair is supported, and the video meets duration limits. Most videos on YouTube have no official dub at all. EarDub does not depend on any of those conditions: it works on almost any YouTube video, with captions on every plan, and without captions on Basic and Pro.

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.
AutoDub is free but works only on YouTube videos that have captions. DubTab translates the audio as it plays, so it also works on live streams, but the voice runs a little behind the speaker. EarDub prepares each sentence ahead, so the voice stays in step with the picture, and it also dubs videos without captions (Basic and Pro), Udemy, Coursera and Bilibili. Full comparison of YouTube dubbing extensions.
Yes. EarDub turns what's said in a video into a natural AI voice in any of 75 languages and plays it in sync with the picture, so you can listen the way you would to a podcast or a dubbed film. You can keep translated subtitles on screen too, or hide them. It works on almost any YouTube video, with captions on every plan, and without captions on Basic and Pro.

Subtitles preserve the original voices but chain your eyes to the bottom of the screen, which is tiring for long videos and useless while multitasking. Dubbing lets you absorb content by listening, like a podcast. With EarDub you do not have to choose: it plays the dub and can show bilingual subtitles at the same time, with the original voice mixed underneath at any volume.
