Voice control for our home electronics is still uncommon. If you want to add a little voice control to your home cheaply, blogger Chipos81 shows off how to do it with a Raspberry Pi.
The system here uses a LightwaveRF system to control the lights, and then taps into the Raspberry Pi which controls everything else. As designed, the system can control the lighting and a few other electronics. Head over to Chipos81's site for the full guide to make it for yourself.
