trouble with flight assistant

I am new to this site and would first like to say hi to you all.
Now, my ?
I have downloaded flight assistant from simvationand have MS speech 5.1 installed as well. I have run the training sessons and have all working in that dept. Flight assistant opens and I can turn it on. But in FS2004 I can not get it to work. Since this is not AutoCAD I am stumped as to fix the prob. Anyone have ideas?
Cheers
