Understand any video in your language instantly
Vaivox is consumer dubbing: built for viewers who want to understand a video, not for creators who publish one. Paste a YouTube link, pick your language, and listen to the video dubbed with a natural AI voice, synced to the original — no subtitles to chase. It works on full lectures, podcasts, interviews and conferences up to 2h30, in 82 languages. Everything runs in the browser: nothing to install, no extension, no software. Free to start: 15 minutes the first month, then 10 minutes per month, no card required. Paid plans from €7.99/month. No lip-sync, no voice cloning, no summaries — the point is simply to understand what was said.
For a language student, Vaivox makes it possible to follow videos in the language being studied without mastering every word. Example: a Spanish student can watch an art history lecture in Spanish and listen to it dubbed in their own language to catch the key points, then go back to the original.
For a professional following training in a language they only half speak, Vaivox opens up the material anyway. Example: an engineer can watch a technical talk in English and listen to it dubbed in their own language, instead of being slowed down by the language.
For someone who watches documentaries, interviews or podcasts published in another language, Vaivox replaces subtitles with a voice in their own language. Example: a history enthusiast can listen to a two-hour Italian documentary in English, keeping their eyes on the images rather than on the bottom of the screen.
For a researcher, Vaivox opens up conference talks and scientific presentations given in languages they do not read. Example: a biologist can watch a conference presentation in German and listen to it dubbed in their own language to catch the details that matter in their field.
Vaivox dubs an online video into your language with a natural AI voice, synced to the original. It is built for the person watching who wants to understand, not for the creator who publishes. You paste a YouTube link and pick your language.
Vaivox is free to start: 15 minutes the first month, then 10 minutes per month, with no card required. Paid plans are €7.99/month (Starter), €12.99 (Medium) and €24.99 (Pro), also shown in dollars and pounds depending on the country.
Vaivox dubs videos into 82 languages, and its own interface is available in those same languages.
Generated files are kept for 90 days and then deleted automatically. Vaivox is meant for personal use: you listen to a video you are watching. The details are set out in the site's privacy policy.
Most alternatives are dubbing tools built for creators: lip-sync, voice cloning, publishing. Vaivox answers a different need, understanding a video you are watching. So the right choice depends on the job: publishing in another language, or understanding.
No. Everything runs in the browser: no installation, no extension, no software to download. You paste a link, pick a language and listen.
