Abstract

In an environment including multiple electronic devices that are each capable of being controlled by a user'"'"'s voice command, an individual device is able to distinguish a voice command intended particularly for the device from among other voice commands that are intended for other devices present in the common environment. The device is able to accomplish this distinction by identifying unique attributes belonging to the device itself from within a user'"'"'s voice command. Thus only voice commands that include attribute information that are supported by the device will be recognized by the device, and other voice commands that include attribute information that are not supported by the device may be effectively ignored for voice control purposes of the device.

Claims

1. A method of recognizing a voice command by a device, the method comprising:

receiving a voice input;

processing the voice input by a voice recognition unit, and identifying at least a first voice command as including attribute information corresponding to the device from the voice input;

recognizing the first voice command as being intended for the device based on at least the attribute information corresponding to the device identified from the first voice command, and

controlling the device according to the recognized first voice command.

2. The method of claim 1, wherein the voice input is additionally comprised of at least a second voice command for controlling at least one other device.

3. The method of claim 1, wherein recognizing the first voice command further comprises:

comparing the identified attribute information of the device against a list of device attributes that are available for voice command control, and

recognizing the first voice command as being intended for the device when the attribute information of the device is identified as one of the device attributes that are available for voice command control.

4. The method of claim 3, wherein the device attributes that are available for voice command control include at least one of a display adjusting feature, volume adjusting feature, data transmission feature, data storage feature and internet connection feature.

5. The method of claim 1, wherein recognizing the first voice command further comprises:

comparing the identified attribute information of the device against a list of preset voice commands that are stored on a storage unit of the device, and

recognizing the first voice command as being intended for the device when the attribute information of the device is identified as one of the preset voice commands that are included in the list of preset voice commands.

6. The method of claim 1, wherein recognizing the first voice command further comprises:

comparing the attribute information of the device against a list of attributes of the device that are currently being utilized by an application running on the device, and

recognizing the first voice command as being intended for the device when the attribute information of the device is identified as one of the device attributes that are currently being utilized by an application running on the device.

7. A device for recognizing a voice command, the device comprising:

a microphone configured to receive a voice input;

a voice recognition unit configured to process the voice input, identify at least a first voice command including an attribute information of the device from the voice input, and recognize the first voice command as being intended for the device based on at least the attribute information of the device identified from the first voice command, and

a controller configured to control the device according to the recognized first voice command.

8. The device of claim 7, wherein the voice input is additionally comprised of at least a second voice command including attribute information for controlling at least one other device.

9. The device of claim 7, wherein the voice recognition unit is further configured to compare the identified attribute information of the device against a list of device attributes that are available for voice command control, and recognize the first voice command as being intended for the device when the attribute information of the device is identified as one of the device attributes that are available for voice command control.

10. The device of claim 9, wherein the device attributes that are available for voice command control include at least one of a display adjusting feature, volume adjusting feature, data transmission feature, data storage feature and internet connection feature.

11. The device of claim 7, wherein the voice recognition unit is further configured to compare the identified attribute information of the device against a list of preset voice commands that are stored on a storage unit of the device, and recognize the first voice command as being intended for the device when the attribute information of the device is identified as one of the preset voice commands that are included in the list of preset voice commands.

12. The device of claim 7, wherein the voice recognition unit is further configured to compare the attribute information of the device against a list of attributes of the device that are currently being utilized by an application running on the device, and recognize the first voice command as being intended for the device when the attribute information of the device is identified as one of the device attributes that are currently being utilized by an application running on the device.

13. A method of recognizing a voice command by a device, the method comprising:

receiving a voice input including at least a first voice command and a second voice command;

processing the voice input by a voice recognition unit, and identifying the first voice command as including attribute information corresponding to the device and also identifying the second voice command as including attribute information that does not correspond to the device;

recognizing the first voice command as being intended for the device based on at least the attribute information of the device identified from the first voice command, and

controlling the device according to the recognized first voice command.

14. The method of claim 13, wherein the device is connected to a local network that includes at least a second voice recognition capable device.

15. The method of claim 13, further comprising:

transmitting information to the second voice recognition capable device identifying the device has been controlled according to the first voice command, and

displaying information identifying the device has been controlled according to the first voice command.

16. The method of claim 13, further comprising:

transmitting information to a second voice recognition capable device identifying the device has not been controlled according to the second voice command.

17. The method of claim 13, further comprising:

receiving information from a second voice recognition capable device identifying the second voice recognition capable device has been controlled according to the second voice command, and

displaying information identifying the second voice recognition capable device has been controlled according to the second voice command.

18. The method of claim 17, further comprising:

displaying information identifying the device has been controlled according to the first voice command.

19. The method of claim 13, further comprising:

displaying information identifying the device has been controlled according to the first voice command.
