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.
