So instead of pressing "~" & "1" to open the ATC window and select the first option I would say "Show ATC" and "One".
Skittles,
I don't know about "Flight Assistant" but I use "Voicemaster" (payware) and in your example above ..... I would say something more like "Tower this is.... " or "Center, this is "... and the ATC window pops open. Instead of "One" it might be "Please say again."
If you load in the voice tags correctly for the various ATC keypresses.... it really works pretty well to emulate actually talking to ATC. ;) Not sure if Flight Assistant supports this though.
So saying.....
"Center, this is Cessna N74JF. Please say again."
....opens the atc fuinction and selects option number 2.
best,
