That sounds Awesome! Microsoft launched talking to your phone using it's TellMe network before Siri came out on Window 7 phones.. Yes, it could use some improvements, but it is still how I enter more than half of my text messages on my Windows 8 Phone.
I use the voice options often when I working on things using my hands. I do get frustrated, as every now and then you have to grab a controller to click a button, or waver your hand to chose a hard drive, but that's about it. Otherwise, I really like it and think it a useful and convenient direction.
Please give it the ability to learn to pause when the phone rings.
