Your Videos Can Now Speak Foreign Languages
Ever imagined your videos speaking English naturally? Not that cold, robotic Google Translate voice — but a natural, professional-sounding voice.
Well, we just launched AI Dubbing (Beta). In short: upload a video → choose from 9 professional AI voices → automatically dub it into other languages. Your videos can now speak 15+ languages.
This Isn't Your Typical Text-to-Speech
The Old Way (Traditional TTS)
Pick a robot voice, have it read translated text out loud. Result: sounds like Siri reading a script — technically correct, but absolutely not you.
Our Way
You choose from 9 curated professional AI voices — each with distinct tone and style. The AI then speaks the target language naturally and expressively.
The result? It sounds like a real person speaking — not a robot reading text. Natural intonation and rhythm throughout.
Five Steps to Dubbed Audio
- Upload your video — same as usual, wait for AI transcription
- Click translate — choose your target language
- Check AI Dubbing — tick the checkbox, read the notice
- Confirm — AI starts translating and dubbing with your chosen voice
- Download MP3 — done in minutes, download your dubbed audio
Faster than making instant noodles. Probably.
The Main Event: YouTube Multi-language Audio Tracks
This is the real game-changer.
In September 2025, YouTube officially opened "multi-language audio tracks" to all creators. You can upload different language audio files for the same video. Viewers can switch languages right in the player — not just subtitles, but the actual voice.
How to Use It
- Generate an English dubbed MP3 using Hey Subtitle's AI Dubbing
- Open YouTube Studio, find your video
- Go to "Languages" → "Add Language" → "Dub" → Upload your MP3
- Done! Viewers can now switch audio tracks
Why This Matters
YouTube's data shows that videos with multi-language audio tracks get over 25% of watch time from non-native language viewers. That means adding dubbing could potentially double your reach.
Your videos can finally "go global." And they'll go global with professional AI voices.
Try It Now
AI Dubbing is available on all plans, including free. Sign up, upload a video, and in minutes your video will be speaking English.
Dubbing is currently in Beta — we're continuously improving quality. We'd love to hear your feedback!
