What is it?

VoxBridge is a communication prosthetic for mute users who need instant, reliable speech in live voice conversations. It lives unobtrusively in the system tray and provides a hotkey-driven overlay for typing messages that are spoken aloud through both your headphones and a virtual audio cable (used as microphone input by Discord, VRChat, etc.).
