Hi everybody, I have a question for you experts. A friend of mine, who is forced on a wheel chair, asked to me if it was possible to switch on / off the lights in his house (or open/close the blinds) by simply using voice commands. Example: he enters his bedroom and speaks "BEDROOM" "LIGHTS" "ON" or "BEDROOM" "BLINDS" "CLOSE" Can this be done? Is there anything existent on the market? Or at least could you please suggest me some resources and devices to "put together" in order to build something like that? My friend reminds me that something similar can be found in cellphones, where you can call a name by clicking a button and pronouncing the name of the receiver. I thank you all for any advice.
