Free YouTube video translator

Synthesia is the best AI YouTube video translator for anyone who needs the finished video to look natively recorded. Most tools stop at subtitles or a synthetic voiceover. Synthesia dubs your video into 140+ languages and accents, clones each speaker's voice so they sound like themselves, and syncs lip movements to the new audio. You can edit the translated transcript before publishing, and share every language behind one link.

Yes. The YouTube video translator is free to use, with voice preservation and lip-sync included.

You can dub your YouTube video into 140+ languages and accents, including but not limited to: English, Spanish, French, German, Portuguese, Italian, Chinese (Mandarin), Japanese, Korean, Arabic, Hindi, Russian, Turkish, Vietnamese, Thai, Dutch, Polish, Swedish, Indonesian, Bengali, and Persian.

Any video with clear speech works, and videos that show someone talking on camera get the most from lip-sync. The link must be to a public video, since private and unlisted videos cannot be pulled. Several speakers in one video are handled automatically, each with their own cloned voice, though people talking over each other is not yet supported. Clean source audio produces a noticeably better voice clone than a noisy recording.

Accurate enough that the first pass is usually publishable, and fully editable where it is not. The transcript editor lets you correct misheard product names, technical terms, and proper nouns in any language version, then retranslate in one click. Editing does not consume extra credits, and edits to one language do not affect the others. Enterprise workspaces can also apply a Translation Glossary so defined terminology stays consistent everywhere.

Most videos are ready to review within minutes. All target languages process in parallel, so ten languages does not take ten times as long as one. Video length is the main factor. For comparison, traditional dubbing runs to script translation, casting, studio time, recording, and sync, typically days to weeks per language.

Yes. Download each language version as an MP4, or export subtitles as SRT or VTT files, which is what you want if you are adding language tracks in YouTube Studio. You can also export WAV audio tracks on their own. Nothing publishes to YouTube automatically, so you stay in control of what goes on your channel and when.

Yes. Subtitles are generated automatically for every dubbed version, and you can download them per language as SRT or VTT files, which is the format YouTube Studio takes for caption tracks. Viewers can toggle subtitles on or off in the Multilingual Player, and if you edit the transcript the subtitles stay in sync automatically.

The difference is control. YouTube's documentation states that you cannot edit automatic dubs, so one mistranslated product name means unpublishing or deleting the whole track. Synthesia gives you the transcript in every language, so you correct it and regenerate before anything goes live. YouTube also dubs most source languages into English only, while Synthesia dubs into any of 140+ target languages from a single upload. And what Synthesia produces is a file you own, so it works in your LMS, on your intranet, or embedded on your own site, not only on YouTube.

Synthesia applies content moderation at the point of creation, combining automated filters with human oversight to prevent misuse. On the compliance side, Synthesia holds SOC 2 Type II, ISO 42001, and ISO 27701 certifications and is GDPR compliant. ISO 42001 is the international standard for responsible AI management.
