Ai Video Dub Realtime Tra

AI Video Dub is a powerful Chrome extension that translates YouTube videos in real-time with natural AI voice dubbing in 70+ languages.

What is AI Video Dub?

AI Video Dub is designed for users who want to watch YouTube content in their
native language without language barriers. The extension uses advanced AI
technology to:

1. Translate video content to your selected target language using Microsoft
Translator
2. Display translated text as an overlay on the video
3. Generate natural-sounding voice dubbing using Microsoft Neural TTS voices
4. Synchronize the dubbed audio with video playback

Core Functionality:

Real-Time Video Translation:
The extension works seamlessly with YouTube. When you click "Start
Translation" in the popup interface, the extension processes the video in
real-time. The translated audio plays simultaneously with the video, allowing
you to understand the content in your preferred language.

AI Voice Dubbing (NEW):
Powered by Microsoft Neural TTS — over 400 natural-sounding voices across 70+
languages. Each language has multiple voice options (male/female). Audio is
pre-generated before playback starts for seamless, synchronized dubbing with
no delays.

Video to Text:
Get the full transcript of any YouTube video with timecodes. Click any line to
jump to that exact moment — perfect for finding key points, quotes, or
re-watching specific scenes. Translate the entire transcript into any of 50+
supported languages. Copy with one click or download as SRT subtitle file for
use in video players or editors.

Subtitle History:
A draggable, resizable panel displays every subtitle that was voiced during
your session, so you can scroll back through the entire conversation. Copy the
whole history with one click for note-taking, language learning, or
documentation.

SRT Subtitle Download (NEW):
Download translated subtitles as standard .srt files. Compatible with all
major video players (VLC, MPV) and video editors (Premiere, DaVinci). Perfect
for content creators who want to add subtitles to their own videos.

Customizable Playback:
- Adjust voice volume and original audio volume independently
- Change speech rate from 0.5x to 1.5x
- Select from multiple AI voices per language
