I'm calling it now. This is going to suffer the same issue all over voice command systems suffer, not everyone is going to speak in a "pleasing North American accent".

^ This.
Some people are just plain going to be difficult to understand, and not only because of accents or speech impediments or what have you, and that's especially going to be a problem if you're speaking in a situation where loud gunfire is emanating from the speakers and you're speaking as quickly as possible because saying a command generally takes longer than pressing a button.
I mean, I'm a very softly-accented Australian, and I could still never get my voice commands to work on SOCOM years ago.
