DubStream — AI Video Dubbing & Translator

AI video dubbing & translator: hear Chinese, Japanese, Spanish & German videos spoken in English or Spanish, in real time.

DubStream adds real-time AI voice dubbing to video across the web. Instead of reading subtitles, hear the video spoken aloud in English or Spanish while you watch. HOW IT WORKS DubStream detects a video's subtitles — in Chinese, Japanese, Spanish, German and more — translates them on the fly, and speaks the translation aloud in a natural voice, automatically synced to the video and ducking the original audio so you can follow along hands-free. FEATURES • Real-time video dubbing and translation into English or Spanish • Works on videos across the web — YouTube and more, not locked to one site • Automatic subtitle detection and translation • Original audio is lowered (not muted) so nothing feels lost • Simple one-click on/off from the toolbar • Free daily dubbing time, with an optional Pro upgrade for unlimited use GREAT FOR • Foreign-language lectures, tutorials, courses, and talks • Anime, dramas, news, and interviews in other languages • Language learners who want audio, not just captions • Anyone who'd rather listen than read subtitles PRIVACY Subtitle text is sent to our processing service only to translate and generate speech. See our privacy policy for details. Note: DubStream works on videos that expose subtitles/captions. Some major streaming services are intentionally excluded. Changes: fixed "your language" → "English or Spanish," added source-language names + YouTube/anime/news/courses keywords, kept your privacy + exclusions notes intact (reviewers like that transparency).
