Aaaah ok. Yes the normal key command is working ! And that's why i use it for my tests.
But i think it came from the configuration of my computer. I try with Voice Activated Command, Game Commander 2 and it's the same : voice control is recognized in windowed mode and not full screen.
So i will try to adjust the windowed mode to take the entire screen and see if it's work. It will seem like full screen huhu .
And yes, i will continue to use sh4speech

. Thx you for ur help
