I struggled for over a month with voice recognition total failure and intermittent failure.
After getting all my settings like the VR thread displays, my VR would work the first time I used it in a game and then never again. Pilots would read back properly and follow instructions ONCE. After that the text box didn't register a thing. Very weird.
After back and forth and back and forth with support (Vic was INCREDIBLY HELPFUL), I still couldn't get past it.
A NEW, QUALITY headphone/mic set COMPLETELY FIXED ALL PROBLEMS. I had a RAZER set which I considered great quality. NO background noise on recordings, very clear, surround sound, etc. But it was about 6 years old.
I bought a RAZER Kraken 7.1 v2 set for other reasons (another game) and low and behold ALL MY VR PROBLEMS DISAPPEARED. This is weird because my old set worked for ONE command each scenario. Obviously the program could "hear" it. Why would it stop after that? I don't know. But----
If you're having VR problems which are persistent after getting the correct VR settings... I would try an up-to-date quality headset.
I start now from the desktop shortcut. I don't even have to "run as administer."
Good Luck
