Use automatic dubbing

Automatic dubbing generates translated audio tracks in different languages to make your videos more accessible to viewers around the world. Videos with these audio tracks are marked as “auto-dubbed” in the video description.

Viewers can indicate their preferred languages for audio, titles and descriptions, or they can switch between the original and dubbed audio tracks for any specific video. When you upload a new video, dubs will be automatically generated. These dubs will be published according to your publication settings. Over time, we may also generate dubs for previously published videos.

Automatic dubbing quality and eligibility

Automatic dubbing helps make information more accessible globally. Over time, dubs may be regenerated to improve the quality, and the quality may not be the same across all languages. Some languages may support expressive speech, which replicates the original audio's pitch and intonation to produce more natural-sounding dubs.

We cannot yet successfully and accurately dub all videos, but we’re continually working on improvements. Dubs are generated automatically, so they might contain errors due to mispronunciations, accents, dialects, or background noise in the original video. We may also have challenges translating proper nouns, idioms, and jargon.

Other issues may arise with speech recognition, like matching the voice used for dubbing to the original voice.

Your video may be ineligible for automatic dubbing due to the following reasons:

• Video Length: The video exceeds 120 minutes.
• Audio Content:
  • The video contains no speech, only music, or very little spoken content.
  • The original audio is in a language we do not currently support.
• Source Language Detection: We were unable to automatically detect the source language of the original audio.
• Speech Pacing: The speech in the original audio is too fast, which would result in an unlistenable, sped-up dub.
• Content ID Claims: The video contains copyrighted content.

Automatic dubbing best practices

To generate more accurate dubs, confirm you have accurately set your original video language to the correct language when you upload the video. You cannot edit automatic dubs. However, you, or someone who speaks the target language, can review dubs before publication.

Access to automatic dubbing

This feature is enabled by default for eligible creators. If you don’t have automatic dubbing enabled, you can use early access to enable it—you’ll need to click Enable in “Advanced settings.”

Available languages

As we evaluate and expand support for additional languages, you may see new languages being evaluated marked as "experimental” in YouTube Studio. For a specific video, you can refer to the Languages page in YouTube Studio for a list of languages available for that video, including which are experimental. Experimental languages will be published according to your channel settings in YouTube Studio on a browser.

Automatic dubbing is supported for videos in the following languages. Languages marked with an asterisk support expressive speech, which replicates the original audio's pitch and intonation to produce more natural-sounding dubs.
