Setup, troubleshooting, billing, and everything about dubbing YouTube videos into your language.
EarDub is a free Chrome extension that dubs YouTube videos into your native language. It extracts the video's captions, translates them with AI, generates natural-sounding speech, and plays it in sync with the video. You can dub into 17 languages — including English, Spanish, Portuguese, Japanese, Korean, Mandarin, Vietnamese, and Turkish — with 60+ voices.
Install EarDub from the Chrome Web Store with the "Add to Chrome" button, then open or refresh any YouTube tab. EarDub officially supports desktop Google Chrome; other Chromium browsers such as Edge may work but are not yet officially tested. Dubbing requires a free Google sign-in, which takes one click.
Open a YouTube video that has captions, 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.
EarDub dubs into 17 languages: English, Spanish, Portuguese, French, German, Italian, Russian, Arabic, Hindi, Japanese, Korean, Mandarin Chinese, Traditional Chinese, Vietnamese, Indonesian, Turkish, and Polish — each with multiple natural neural voices (60+ in total). Source videos can be in any language that has captions; automatic language detection works best with English, Japanese, Korean, and Spanish videos.
The free plan includes 30 minutes of dubbing per day, up to 3 videos daily, with each video up to 60 minutes long. Basic is $9.99/month and includes 60 hours per month, videos up to 3 hours, up to 20 videos daily, context-aware AI translation, and email support. Pro is $19.99/month with unlimited dubbing time, video length, and daily videos, plus context-aware AI translation and email replies within 24 hours. Both paid plans can also be billed yearly for less than the price of 9 months (3 months free): Basic $89/year, Pro $179/year.
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.
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 sentences always play to completion: 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 parts can be skipped to keep up. 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. Confirm the video has captions: check the CC button in the player. 3. Check whether this month's free dubbing quota is used up in the extension popup. 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.
EarDub builds the dub from the video's captions, so a video with no captions at all cannot be dubbed yet. Most popular videos have at least auto-generated captions, which work fine. If the CC button is missing entirely, the creator disabled captions and YouTube generated none. Speech-recognition support for caption-less videos is planned.
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 (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 and on the course sites you allow (Udemy, Coursera), and stays completely idle on every other website.
No. The extension runs only on youtube.com, plus udemy.com and coursera.org if you allow them, so it cannot read, modify, or slow down any other site. 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.
Yes. Dubbing requires a free sign-in with Google. Signing in lets us track your plan usage, sync it across devices, and manage paid subscriptions. It takes one click and no password.
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. Checkout and billing are handled by Waffo (our Merchant of Record); 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 is sent to our servers for translation and speech synthesis, and the resulting audio is cached so repeat views are instant. EarDub does not read your browsing history, does not track you outside the video pages it dubs, and 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 any captioned video, even when the first two options are missing.
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 every video that has captions, manual or auto-generated.
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.
