A voice-activated remote control unit which is adapted for use with one or more electrical apparatuses, such as a TV set, a DVD player, a stereo system, an air conditioner, for the purpose of allowing the user to remotely turn on/off and control the operations of these electrical apparatuses through voice-activation. The voice-activated remote control unit comprises voice input means which can pick up the user/s natural voice command and converting it into an digital voice signal. A command code database is used for storing a predefined set of remote-control command codes and corresponding voice commands; and a voice recognition unit is used to perform a voice recognition algorithm on the digital voice signal to thereby recognize the user's voice command, and which is further capable of retrieving the corresponding remote-control command code from the command code data-base. Finally, a wireless signal emitter, such as infrared (IR) signal emitter is used to modulate the retrieved remote-control command code into an IR signal and emitting the IR signal to the electrical apparatuses to cause one or more of the electrical apparatuses to operate accordingly.
