You run it yourself: download the repo, launch start.bat, and it opens as a local Gradio web page on your own PC — there's no hosted cloud version.How do I get it running?On Windows, download the repo and run start.bat — it uses uv to automatically install Python, PyTorch, and all other dependencies into an isolated installerfiles/ folder, with no manual setup needed.
On Windows, download the repo and run start.bat — it uses uv to automatically install Python, PyTorch, and all other dependencies into an isolated installerfiles/ folder, with no manual setup needed.Do I need an NVIDIA GPU to run this?Yes — it's built on CUDA-accelerated PyTorch (2.8.0+cu128) and is confirmed to run well on Windows with an NVIDIA GPU. CUDA Toolkit and Visual Studio Build Tools are no longer required since all dependencies now ship as prebuilt wheels.

CUDA Toolkit and Visual Studio Build Tools are no longer required since all dependencies now ship as prebuilt wheels.Is active development still happening?No — the maintainers paused Voice-Pro development to focus on another project (WeConnect), though they open-sourced the whole codebase and made it free. Also note that only Windows + NVIDIA GPU is verified; Mac and Linux behavior is unconfirmed.
