DEDUPEDVoice cloning. Only clone voices you own or have permission to use.
Who it is forA teacher or marketer making tutorials who does not want to record narration again for every edit.
The problemRe-recording voice-overs for every script change is slow, and cutout tools usually need cloud uploads.
The outcomeA tutorial with narration in your own cloned voice, a cut-out presenter and clean audio, made locally.
What you need first
- macOS, Windows, Linux or Android (iOS sideloaded)
- AI models for captions, voices and cutout download once from Settings, then work offline
- To build from source: Rust 1.93+, FFmpeg 7+ development libraries, cmake and a C++ compiler
Steps
- Install Concat and download the voice and cutout models from Settings
- Clone a voice from a few seconds of your recording, or pick a free local voice
- Generate the narration with text-to-speech from your script
- Remove the background from your webcam footage and place it over the screen recording
- Use one-switch voice cleanup to denoise and level loudness, then export
Prompt for your agent
