Totally fair question! Because LAVOICE runs local offline speech recognition (sherpa-onnx) and an independent multiplayer netcode without a central server, it includes a small local runner/extension (.exe) to handle audio pipes. Also, since this is a free indie test build, it doesn't have an expensive Microsoft digital publisher certificate yet — which triggers Windows Defender warnings. The source files are completely safe, and you can verify the SHA-256 hash or check the local logs anytime. But if you're ever in doubt, always trust your system safety first! :D
