How to Dub YouTube Videos: Multi-Language Audio Tracks Step by Step

To dub a YouTube video, you make an audio-only file in the new language that runs the same length as the video, then add it in YouTube Studio under Languages → Add language → Dub. Viewers whose preferred language matches hear that track automatically, and everyone else can switch tracks in the player settings. It is still one video with one URL, so views, comments and watch time all stay in one place. Manual audio tracks are available to channels with access to YouTube’s Advanced features.

Why add audio tracks instead of uploading a second video

Before multi-language audio, the usual way to reach another language was a separate channel or a re-upload. That split your views and comments and left the new channel starting from zero. An extra audio track keeps everything on the original video. According to YouTube’s help page on multi-language audio, creators who added dubbed tracks saw more than 25% of their watch time come from views in the video’s non-primary language.

What you need

• Advanced features on your channel. YouTube makes manual multi-language audio available to channels with access to Advanced features. You can check your status in YouTube Studio under Settings → Channel → Feature eligibility.

• An audio-only file per language. YouTube asks for a supported audio-only format, roughly the same length as the video. A video file won’t be accepted as a dub track.

• A dub that matches the picture. The track must line up with the video from the first second, keep the music and sound effects, and leave on-screen moments where they belong.

YouTube’s automatic dubbing vs your own dub

YouTube now also generates dubs itself for eligible channels. It helps to know where it ends, because it decides whether you need your own tracks at all.

Source: YouTube Help on automatic dubbing, checked October 2026. If YouTube’s dub covers your language and you are happy with it, use it. When it mistranslates your terms, picks the wrong voice, or doesn’t cover a language you need, make your own track. If an automatic dub already exists for a language, delete it before you upload yours.

Step by step: from your video to a dubbed audio track

Step 1: Dub the video

Upload the same video file you published on YouTube to BlaBlaScribe AI Dubbing. Check the transcript, pick a language from 27, and choose a voice for each speaker, or clone your own voice from at least 20 seconds of your speech in the file. Listen to the free 15-second preview, then dub the whole video and review any lines flagged as too long. The full process is in our guide on how to dub a video with AI.

Step 2: Download the track as audio only

In the export window, choose audio instead of video and pick the sound:

• Voice, music and sounds: the original voice removed. This is the one you want for YouTube in most cases.

• Voice over the quiet original: a documentary-style voice-over, useful for interviews where the real voice should stay faintly audible.

Download it as WAV for the best quality, or MP3 or M4A for a smaller file. The track is built on the timeline of your original file, so it already matches the video’s length.

Step 3: Upload it in YouTube Studio

1. Open YouTube Studio on a computer and go to Languages.

2. Select the video and click Add language. Choose the dub language.

3. Next to Dub, click Add and select your audio file.

4. Publish. Repeat for each language.

Step 4: Localize the title, description and captions

A dubbed track makes the video watchable. Translated metadata makes it findable. In the same Languages section, add a translated title and description for each language; write them for how people search in that market rather than word for word. Add a subtitle track in the same language too: viewers who watch muted or need captions still get them. A subtitle translator produces an SRT from the same translation, with timestamps intact.

What it costs

Each language uses as many dubbing minutes as the video is long, and the translation is included. Packs start at $15 for 10 minutes and go down to $1.00 per minute in the 100-minute pack ($100). A 9-minute video in Spanish, Portuguese and German uses 27 minutes, covered by a 30-minute pack for $39. Prices are on the pricing page.

Which videos to dub first

• Evergreen videos with steady search traffic. Tutorials, explainers and reviews that still get views months later pay the dub back for longest.

• Videos already watched in another language. In YouTube Analytics, check where viewers come from and which subtitle languages they turn on. Those markets are already asking for a dub.

• Videos that need eyes on the screen. Screen recordings and demos lose viewers who must read subtitles and watch at the same time. Our guide to subtitles vs dubbing goes through the trade-off.

Common problems

• The upload is rejected. Check that you uploaded an audio file, not the MP4, and that it is about the same length as the video. A dub track exported from a trimmed version won’t line up.

• The voice drifts out of sync. Make sure you dubbed exactly the file you uploaded to YouTube, not an earlier cut.

• Viewers still hear the original. The track plays by default only for viewers whose preferred language matches it. Others can pick it in the player’s audio track setting.

• Music sounds thin in the dub. Use the “voice, music and sounds” option rather than the voice alone, so the background stays at full level under the new voice.

Frequently asked questions

Can every YouTube channel add multi-language audio?

YouTube makes manual audio tracks available to channels with access to Advanced features. Automatic dubbing is turned on by default for eligible channels and can’t be edited.

Do dubbed audio tracks count as one video?

Yes. Views, watch time and comments from every language add up on the same video and URL.

What file format does YouTube need for a dub?

An audio-only file roughly as long as the video. A WAV or MP3 exported from BlaBlaScribe works.

Can I dub YouTube Shorts?

For short vertical clips, burned-in subtitles are usually the better choice, because many viewers scroll with the sound off. Add Subtitles to Video exports an MP4 with the captions burned in.

Should I use my own cloned voice?

For personality-driven channels, often yes: viewers follow a person, and a clone keeps your voice in the new language. Clone only your own voice or one you have permission to use. See voice cloning rules for dubbing.

The bottom line

Multi-language audio turns one video into several language versions without splitting your channel. Dub the evergreen videos that already pull viewers from abroad, export each language as an audio-only track, upload it under Languages, and translate the title and description so the new audience can find it. For subtitles only, start with the video translator.
