Abstract
An apparatus and method for executing a voice command in an electronic device. In an exemplary embodiment, a voice signal is detected and speech thereof is recognized. When the recognized speech contains a wakeup command, a voice command mode is activated, and a signal containing at least a portion of the detected voice signal is transmitted to a server. The server generates a control signal or a result signal corresponding to the voice command, and transmits the same to the electronic device. The device receives and processes the control or result signal, and awakens. Thereby, voice commands are executed without the need for the user to physically touch the electronic device.
