AI Video Dub - Realtime Translation & Voice

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, with automatic fallback engines for reliability 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: Powered by Microsoft Neural TTS — over 300 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. Use Your Own Subtitles (NEW): Found a video with no subtitles, or have a better translation of your own? Upload an .srt or .vtt file and the extension dubs straight from it. The file's language is detected automatically, so one click is all it takes — and if your file is already in the language you want to hear, no translation step runs at all. Drag and drop works too. Quick Access From The Player (NEW): A dubbing button sits right in the YouTube player controls, next to autoplay. One click opens the language picker without leaving the video or hunting for the extension icon in the toolbar. 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 70+ 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: 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 - Show or hide translated and original subtitles - Drag subtitle overlay to your preferred position - Drag and resize the Video to Text and Subtitle History panels - Searchable language selector for quick language switching Multi-Language Support: The extension supports translation and voice dubbing in 70+ languages including: English, Spanish, Portuguese, Russian, French, German, Chinese, Japanese, Korean, Hindi, Arabic, Turkish, Italian, Polish, Dutch, Indonesian, Vietnamese, Thai, Ukrainian, Czech, Armenian, Romanian, Swedish, Greek, Hebrew, Bengali, Urdu, Persian, Malay, Filipino, Hungarian, Finnish, Danish, Norwegian, Bulgarian, Slovak, Croatian, Serbian, Catalan, Tamil, Telugu, Marathi, Gujarati, Kannada, Malayalam, Nepali, Azerbaijani, Georgian, Swahili, Afrikaans, Kazakh, Uzbek, Somali, Punjabi, Pashto, Yoruba, Burmese, Lao, Amharic, Sinhala, Khmer, Zulu, Albanian, Belarusian, Mongolian, Lithuanian, Bosnian, Slovenian, Galician, Macedonian, Irish, Latvian, Estonian, Icelandic, and Welsh. A few languages are translated as on-screen text only, because no neural voice exists for them yet. The extension tells you when that is the case. Requirements: AI Video Dub needs a transcript to work from. Most YouTube videos have one — either uploaded by the creator or auto-generated by YouTube. For the videos that have none, upload your own .srt or .vtt file and the extension dubs from that instead.
