- Unreal Engine 5.7, Windows x64
A free, open-source Unreal Engine 5.7 plugin that runs the small Kokoro-82M voice model on the CPU, so lines are spoken at runtime with no cloud service and no per-character fee. It ships 48 voices across English, Spanish, Hindi, Italian, Brazilian Portuguese and Mandarin, with German, Dutch and Turkish as experimental options, and packaging copies the model into your build so players never download it. It's very new and run by one developer (Windows x64 only, a handful of GitHub stars, no releases yet), so test it before building a game around it.
