Real-Time-Voice-Cloning is an open-source audio project by CorentinJ (CorentinJ/Real-Time-Voice-Cloning on GitHub). It has 60,173 GitHub stars and 9,377 forks, is released under the NOASSERTION license, and was last updated on GitHub on 9 March 2026.
Decide what you want from Real-Time-Voice-Cloning and check the README and requirements to confirm it fits your setup and Python environment.
Clone the repository from GitHub (github.com/CorentinJ/Real-Time-Voice-Cloning) or use the documented install channel if you do not need the source.
Follow the README quickstart to install dependencies and set any required configuration or credentials.
Work through the README's first example end to end, then adapt it to your own project or data.
Clones a voice from just a few seconds of reference audio.
Generates arbitrary speech in the cloned voice in real time.
Ships an interactive toolbox demo for trying cloning without code.
Also provides a command-line demo for scripted use.
Implements the published encoder, synthesizer and vocoder papers listed in the README.
Optional pretrained models are available to download, per the README.
Start by getting the source and entering the project directory.
git clone https://github.com/CorentinJ/Real-Time-Voice-Cloning.git
cd Real-Time-Voice-CloningThe README now drives everything through uv; install uv first if needed.
pip install -U uvLaunch the GUI toolbox with the CUDA or CPU extra depending on your hardware.
uv run --extra cpu demo_toolbox.pyIt is maintained by CorentinJ and contributors on GitHub, where the repository github.com/CorentinJ/Real-Time-Voice-Cloning is the canonical home for code, issues and releases.
Yes — it is open source under the NOASSERTION license. Read the license in the repository for what is permitted, including any conditions on redistribution or commercial use.
No. Everything runs locally; a GPU is recommended but a CPU path is documented.
Compared with Coqui TTS: This project focuses specifically on fast voice cloning from seconds of audio, while Coqui TTS is a broader multi-model TTS toolkit.
Clone github.com/CorentinJ/Real-Time-Voice-Cloning, follow the README quickstart to install it, and run the documented first example before adapting it to your own work.
