Real-time Video Translator & Dubbing - DubTab

DubTab helps you understand videos, livestreams, and online audio instantly by translating speech as it’s spoken, showing live subtitles, and playing a natural AI voice in your language.

If you’ve ever wanted a foreign video to just speak your language — DubTab makes that possible, directly inside your browser tab.

⚙️ What DubTab does

When audio is playing on any website, DubTab can:

- Translate spoken content in real time
- Display live translated subtitles on screen
- Play a natural-sounding AI voice that speaks the translation
- Optionally show bilingual subtitles (original + translation)

No waiting, no uploading files, no post-processing.
Just press play and understand instantly.

🎧 Real-time AI voice dubbing (core feature)

DubTab’s main strength is low-latency speech-to-speech translation.

Instead of forcing you to constantly read subtitles, DubTab listens to the audio, translates it on the fly, and speaks the translation aloud with AI voices.

This makes long videos, tutorials, and livestreams much easier to follow — even when you’re multitasking.

📝 Live & bilingual subtitles

Prefer reading? Or want both?

- Live translated subtitles appear as the speaker talks
- Bilingual mode shows original and translation together
- Ideal for language learners or accuracy checking

You can switch subtitle modes anytime while watching.

🎙️ Multiple voices, your choice

Not all voices are comfortable to listen to.

DubTab lets you choose from multiple AI voices, adjust the volume balance between original audio and dubbed voice, and create a listening experience that feels natural and clear.
