An electronic device controlling system that provides an instruction via voice for an operation of a speech recognition-capable electronic device includes a control device and a voice output device capable of communicating with the control device. The control device includes a first input unit that receives, from an operator, a first input to which a first operation instruction for the speech recognition-capable electronic device is assigned; and a transmitter that, when the first input unit receives the first input, transmits, to the voice output device, first information for communication corresponding to the first operation instruction assigned to the first input. The voice output device includes a receiver that receives the first information for communication from the control device; and an output unit that, when the receiver receives the first information for communication, outputs a first voice for the first operation instruction based on the first information for communication.
