Dubbing is very different from subtitles, and in many ways, subtitles might lose the essence of a message in translation. The audio files are recordings of the video's audio in foreign languages. For example, a creator can hire voice actors to record audio for their English video in Spanish, Hindi, and other languages. Afterward, they would upload those audio files to the original video.
YouTube's Multi-Language feature eliminates the need for creators to upload the same video on different versions of their channels to capture audiences in different languages. Creators can upload a single video with multiple audio files, consolidating their content for a more focused approach.
Using YouTube's Multi-Language feature is as simple as it gets. The feature is available on mobile and desktop, and anyone can use it. If you come across a YouTube video with your local language added, it should play in that language. But we'll show you how to change the audio to a different language, just in case.
It's important to note that creators don't need to use YouTube's Multi-Language audio; it's optional for creators who want to reach a wider audience. At the time of writing, more than 40 languages are available in YouTube's Multi-Language feature, but that doesn't mean that all videos will have that many languages added.
The list of languages shown in a video's Audio track section depends on how many audio files the creator has added to that particular video. If you can't find your local language on the list, it means the creator hasn't added the relevant audio file. It could be available in the future, but since there's no guarantee, you might be better off enabling closed captions on YouTube.
English may be a universal language, but it's not everyone's home language. And while many bilingual people may be fluent in English, they might be more comfortable consuming content in their home language. YouTube's Multi-Language feature allows viewers to enjoy YouTube content in a meaningful way.
