A voice-controlled electrical adapter includes a plug adapted to engage for example a wall outlet to supply electrical power to the adapter and a socket adapted to receive the plug of an electrical appliance and a voice control circuit electrically connected between the plug and the socket to form a normally-open electrical loop therebetween. The voice control circuit includes a microprocessor based processing means having a memory to store therein a reference instruction, a microphone to receive and apply a user's instruction to the microprocessor which identifies the user's instruction by comparing the user's instruction with the reference instruction and operate in response thereto to control a switching circuit to selectively close the electrical loop to so as to allow the electrical power to be supplied from external power source to the electrical appliance. Visual and vocal output devices may be provided and controlled by the microprocessor to indicate the operation and status of the adapter. The microprocessor may be programmed to perform a learning mode which allows the user to input his or her voice as the reference instruction stored in the memory. If desired, more than one set of socket may be provided and arranged in parallel with each other for connection with more than one electrical appliance.
