The Benefits of Multi-Language Audio Feature

Global reach

The multi-language audio feature allows content creators to reach a global audience. The videos will be accessible to non-native speakers, broadening the creator's audience and increasing their potential viewer base.

Improve engagement

Viewers are more likely to engage with videos they understand fully. This leads to higher watch times and more interactions, as evidenced by the reported 15% increase in watch time from non-primary languages.

Easy management

Instead of managing multiple localized channels simultaneously, this feature allows creators to upload videos with corresponding audio tracks once. Now you can spend more time creating quality content while efficiently catering to a global audience

How does it work?

Step 1: See if you are eligible for the feature

YouTube is rolling out this feature slowly, so you need to check if you have access to it first. Go to YouTube Studio -> Subtitles, then select a video to see if you have an “Audio” column like the screenshot below.

Why don’t I have access?
