YouTube Multi-Language Audio: Upload Your Own Dubs

November 10, 2026

YouTube's multi-language audio feature allows you to upload audio tracks in different languages to a single video or Short. This helps you expand your global reach without managing multiple separate channels. However, this feature does not automatically generate these dubbed tracks. You must record or obtain your own dubbed audio files before uploading them.

If YouTube has already generated an automatic dub for your selected language, you must delete it before you can upload your own custom version.

A dub needs fixing because its quality depends on the original video, so some lines often need fixing, and that takes a tool that is both flexible and easy to use. On the Velotras Video adjustment page, which works even on a phone, you can hear each line in the original voice and in the dubbed voice, correct what you need, and the video is redone with your corrections.
