US Patent 9741344 System and method for operating devices using voice commands

System and method for operating electric devices based on voice commands, as well as electric devices that can be controlled via voice commands. An electric device comprises an audio sensor to capture audio that contains speech; and a transmitter to transmit the captured audio to a remote server, together with a dictionary identifier that indicates to the remote server which particular dictionary or vocabulary-set to utilize for performing speech recognition on the recorded audio. The remote server performs speech recognition using the relevant dictionary table; and selects a command-code that is transmitted back to the electric device, to trigger an operational modification of the electric device.
