How to Add an AI Voice-Over (Dub) to YouTube Videos

Subtitles make you read. A voice-over lets you listen. Here's how to dub any YouTube video with a natural AI voice in your language — without downloading, editing, or leaving the player.

Dubbing vs. subtitles vs. downloading

There are three common ways to deal with a foreign-language video:

• Subtitles — fast, but you have to keep reading and you miss the visuals.
• Download & edit — accurate, but slow and technical (you need software and re-uploads).
• Real-time AI dubbing — you hear the translated voice over the original, instantly, while you watch.

For everyday viewing, real-time dubbing wins: no files, no editor, no waiting.

Add a voice-over in 4 steps

1. Install voced from the Chrome Web Store and sign in.
2. Open the YouTube video you want to dub.
3. Choose a voice and language in the voced panel — preview voices before you commit.
4. Hit “Enable dubbing.” The original ducks under a synced AI voice-over.

How natural are the voices?

voced uses modern AI text-to-speech, so voices sound natural and conversational rather than robotic. You can choose male or female and different timbres, and preview each one before starting. The translation itself is generated from the video's captions or its audio, then voiced and kept in sync with the picture.

What it costs

The extension is free. Any video already dubbed by another user plays for free from a shared library. You only pay — per second, no subscription — for new dubs you generate yourself, and your dub then becomes free for everyone else. Have a launch promo code? Redeem it for free hours.

Frequently asked

Can I dub a video that has no subtitles?

Yes. voced can transcribe the audio directly when captions are missing.

Does the original audio disappear?

It's ducked (lowered) under the voice-over so the dub is clearly audible, like a professional voice-over.
