What kind of microphone is suitable for use listening to an entire room for voice control purposes?
I've noticed the microphone array in the Kinect devices seems to be pretty good as this (still not as good as I'd like though). Should I go with one really good microphone or several simpler ones scattered around?
Also, what exists regarding to connectivity, i.e. are there any wlan microphones? Or should I use something else to avoid cables all over the place?
