A keen Raspberry Pi user, called Steven Hickson, has been experimenting with using voice commands on a Raspberry Pi to control a variety of applications. According to Steven, the software is very flexible and you can even assign devices keywords, plug them into the software, and control them too.
An application this could be used for is and Internet of Things home. Perhaps controlling lighting, opening/closing curtains, and turning the TV on and off. I would love to see something like this in action!
Take a look at the video below to hear Steven talk about it.
