Many many years ago I used something called Vorecone on an Amiga to do voice control. The best I could say is that you could get it to work. However if there was any background noise it would have to be retrained. Things may have progressed in the past few years but there were some basic problems with voice recognition that IMHO are hard to resolve in order to get 100% reliability every time. Most of those systems required a training session so it would capture your voice input for the particular command. If you turned a fan on in the same room later on it might require retraining. This would be even more difficult in a media room where you have surround sound and music or soundtracks playing at different levels all the time. I know some of the voice systems the phone company uses now are pretty good. They used a huge sample of different people to generate the matrix used to recognize your voice input. And in my experience even those systems have trouble some times. I personally prefer mashing the buttons to respond to those systems. One place I worked tested some voice recognition systems that were used for access control. Had the same problems with those due to ambient background noise. They used a rolling set of three samples to track any changes in a persons voice. Used in the right environment where the background noises stayed the same at all times it would work reasonably well. With any kind of back ground noise it would have problems. And if you turned the sensitivity down to low anyone could get in. :)
