@GeorgeS2019 I tried your code this weekend. ONNX runtime works fine on Godot. That's great! I need to work on the vocoder which depends on C++ code, that won't be that difficult.

This uses Voice100 to speak with Godot. https://github.com/kaiidams/Voice100Godot . The repo has two dlls, Voice100Sharp.dll for managed and voice100_native.dll for Windows 64bit.
