I've had many many chats with GMs over the functionality of voice controlling games and avoiding Blizzard's defination of automation. I have the following move type commands setup, and I have confirmed with a GM they are fine.

Giving the voice "Turn 3 O'Clock" and my characters will turn to the 3 O'Clock position relative to their current position. To do this the voice command triggers the Right arrow key presses and holds it down for about 1 seconds. Likewise for "Turn 6 O'Clock" but holds the key down for about 2.5 seconds.

What you can not do is send more than ONE key press per voice command. You have to look at it like this, If you can perform the same function by pressing a single mapped key (or modified key combination - ctrl alt shift) on your keyboard, such as "A" then you can do it via a voice command.

Xuthus is right, your voice does change when you get excited and it can sometimes inpact the recognition performance. But I've been using Dragon for quite a while and its been "trained" very well over that time. Regardless of the pitch in my voice or the scream as I yell for a heal its usually accurate.

But there are times when it doesn't do what its told and is a great cause of frustration! Because you think if you had just pressed the button instead of using the voice command then you would have been able to kill that boss and not wiped. But thats a decision you have to make for yourself. I've become so reliant on voice control that I don't remember half of my key bindings for my abilities. Basically without voice control I would have to learn to button bash again.
