How DubbyJam works
Upload speech audio or video, assign voices, generate a dubbed track, and refine individual cues before downloading the result.
Steps
Upload audio or video
Create a project and upload speech audio or an MP4/MOV video with an audio track. DubbyJam extracts the audio for analysis and keeps the original picture for video export.
Map character voices
Review detected speakers, optionally rename roles, and pick a TTS voice for each. Preview samples before you commit.
Generate the dub
After you set the voices, one action runs translation, timing refinement, and export. The result view lets you refine individual cues when needed.
Download
When export finishes, download the dubbed audio files; video projects also get a finished video with the original picture and new audio. You can regenerate after changing voices or script.
Review and refine
After the first export, use the result timeline and cue heatmap to find lines that need attention. Each cue can be edited and re-synthesized independently; the final download is updated automatically.
What “minutes” mean
Billing minutes are tied to successful dubbing / TTS usage on your projects (plan quota and optional top-ups). Analysis of the source file is part of the project flow; check Pricing for included monthly minutes.
