Method and apparatus for executing voice command in electronic device

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.

What is claimed is: 
     
         1 . A computer program product comprising one or more computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on an electronic device, causes the device to:
 recognize a wakeup command in a voice signal received through a microphone of the electronic device, wherein the voice signal further includes a voice command subsequent to the wakeup command, where there is a duration of silence between the wakeup command and the voice command;   in response to the recognizing the wakeup command by the electronic device, transmit a signal including the voice command of the voice signal to a server for conducting speech recognition on the voice command through a transceiver; and   perform an operation responsive to a control signal, corresponding to the recognized voice command, received from the server.   
     
     
         2 . The computer program product of  claim 1 , wherein the wakeup command comprises at least one word which is predefined or set by a user. 
     
     
         3 . The computer program product of  claim 2 , wherein the recognizing comprises recognizing the wakeup command based on information on a specific user voice, and wherein the information is acquired from the voice signal, corresponding to the wakeup command, spoken plural times by the specific user in advance. 
     
     
         4 . The computer program product of  claim 3 , wherein the transmitting the signal comprises transmitting the signal including both of the wakeup command and the voice command. 
     
     
         5 . The computer program product of  claim 3 , wherein the wakeup command included in the voice signal is received while the device is displaying a lock screen on a display or is in idle mode. 
     
     
         6 . The computer program product of  claim 5 , wherein, in response to recognizing the wakeup command, the computer readable program further causes the device to unlock the lock screen or change from the idle mode to active mode. 
     
     
         7 . The computer program product of  claim 6 , wherein, in response to unlocking the lock screen or changing from the idle mode to the active mode, the computer readable program further causes the device to display a visual indication related to a voice recognition. 
     
     
         8 . The computer program product of  claim 7 , wherein the transmitting the signal comprises transmitting the signal including both of the wakeup command and the voice command. 
     
     
         9 . The computer program product of  claim 1 , wherein, in response to recognizing the wakeup command, the computer readable program further causes the device to provide a visual indication related to a voice recognition via a display of the device.
