What is DubbyJam
DubbyJam is a web app for AI dubbing: upload speech audio or an MP4/MOV video, translate the dialogue, assign voices per character, and download a dubbed track or finished video.
In one sentence
You give DubbyJam a speech recording or a video with an audio track; it returns a new-language audio track and, for video inputs, a finished video with the original picture and the dubbed mix.
What it is
- AI transcription and speaker separation on uploaded audio or video audio
- Translation into a target language (with optional style instructions)
- Text-to-speech per character / speaker with chosen voices
- Simple mode: one-click generate from voices to export
- Result review: edit individual cues, re-synthesize them, and download the refreshed output
What it is not
- Not a lip-sync or talking-head video editor — video output preserves the picture and replaces its audio, without mouth animation
- Not a live streaming / real-time call translator
- Not a substitute for professional studio casting when you need celebrity voices or broadcast-grade direction
Who it is for
Creators and editors working on YouTube videos, podcasts, game commentary, and bilingual shorts who want a second-language dub without hiring a full voice cast for every draft.
