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.
RTX 50 series GPUs (5070 / 5080 / 5090) require the -nvidia50 variant. China users: select the matching version 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.
