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.

Eligibility

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 by clicking Enable in “Advanced settings.”

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.
• Copyright Claims: The video contains copyrighted content.

Available languages

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.
