DEDUPEDWho it is forYouTuber or course maker who wants one video to reach viewers in another language
The problemHiring dubbing or paying per minute for cloud dubbing is expensive for a small channel.
The outcomeA dubbed version of the video with speech timed to the original, made locally.
What you need first
- macOS, Windows or Linux desktop (Intel Mac runs the UI only and needs a remote backend)
- NVIDIA GPU (CUDA) or Apple Silicon (Metal) recommended; CPU-only works but is slower and needs about 5 GB free disk
- Git, Node.js 22+, Bun and Rust/Cargo only if building from source
- Speech models are downloaded on demand through the app; no paid keys or accounts required
Steps
- Install the app from the latest release or with the one-command installer.
- Open the Video dubbing workspace and load your video file.
- Pick the target language and a voice, then install any model the app asks for.
- Run the dub and review the result against the original.
Prompt for your agent
Using debpalash/VoiceStudio, dub <video file> into <target language> through the Video dubbing workspace. Check that the dubbed speech stays in sync with the original and report any segments that drift.
Caveat. Dubbing quality varies by language and engine, and a CPU-only run will be noticeably slower on long videos.
