Aussie accent here too! I went through the windows/Microsoft speech recognition thing a few times and that made it loads more accurate. That is the key I reckon!
I would have a shot now mate... I, too am new to ARMA and am finding "Articulate" absolutely brilliant. Very easy to install and really allowing me to enjoy ARMA in a much deeper way, a lot more quickly than I expected. Jump in ATTACKM0DE!
