I am developing an app for industrial automation that requires frequent user input. I am exploring the idea of using voice input to input data. The problem is the application will never have access to the internet during use. This is due to being in the middle of nowhere and security requirements. So I am looking for voice control libraries/systems to control an app that can be installed on a Windows 7/10 machine.

Has anyone had any success with a completely self-hosted voice control system?
