Train your own custom voice — fully visual, no command line needed.
Free Tool · No Activation RequiredThe training tool is built into the KOA launcher, but training requires the GPT-SoVITS runtime environment.
Download the official package (~8 GB) from the links below, extract it, and bind the directory in KOA.
Pick v2pro-20250604. The Yuque page lists several versions, and the training panel supports only this one. The V5 package released in October 2026 does not work with it.
RTX 50 series GPUs (5070 / 5080 / 5090) need v2pro-20250604-nvidia50. China users: find that build on the Yuque page. International users: download the nvidia50 build here.
Choose your download source above and extract the package with 7-Zip to any location.
In the KOA launcher, go to the Tools page and find "GPT-SoVITS Voice Training Tool". Select the directory you extracted. KOA will auto-detect it and inject the training panel.
Click "Launch" and the training panel will open in your browser. A built-in beginner guide walks you through every step.
This tool is built on the open-source project GPT-SoVITS (MIT License) and its community ecosystem. It is a free bonus tool bundled with KOA and is not part of the paid activation scope. Please do not purchase this tool from any channel; voices you train should be used for personal purposes only, in compliance with your local laws and regulations.
