I use FS2crew for 737 NGX; it works flawless. After disconnecting FS2crew, I do the following:
1. I use a registered version of VAC Voice Recognition software.
2. I setup a VAC profile with PF3 hotkeys.
3. I test PF3 VAC profile with the Notepad and with CH Manager: keys are emmitted correctly with an efficiency exciding 95% ( even with my local accent).
4. I set up PF3 for using VR with the 2 methods explained in the manual: PPT set to 10 and 20 second, without VCP voice and with VCP mode and automute set.
5. PF3 does not "hear" any of the keys emmitted by VAC but continues to respond to keys emmited by the keyboard.
I'm certainely doing something wrong

Any advices or ideas would be most welcome.
Thanks in advance.
