Electronic device for identifying command included in voice and method of operating the same

1. An electronic device comprising:

a communication module;

a plurality of microphones; and

a processor,

wherein the processor is configured to:

identify a position of a sound source based on a voice received through the plurality of microphones;

identify whether the position of the sound source is included in a first zone between the electronic device and an access point wirelessly connected with the electronic device, wherein the first zone includes a path through which a communication signal is transmitted from the access point to the electronic device;

identify whether a position of a user is included in the first zone based on a comparison between the communication signal received from the access point and a preset communication signal stored in the electronic device, when the position of the sound source is included in the first zone, wherein when the user is in the first zone, the communication signal does not correspond to the preset communication signal due to a user's interference;

based on identifying that the position of the user is included in the first zone, determine to execute a command included in the voice; and

based on identifying that the position of the user is not included in the first zone, determine to refrain from executing the command included in the voice.

2. The electronic device according to claim 1 , wherein the processor is further configured to:

identify whether the voice has been uttered by the user by comparing the position of the user with the position of the sound source.

3. The electronic device according to claim 2 , wherein when the position of the user matches the position of the sound source, the processor is further configured to determine whether to execute the command by comparing the voice with a prestored voice signal of the user.

4. The electronic device according to claim 2 , wherein when the position of the user matches the position of the sound source, the processor is further configured to decrease a threshold for executing the command included in the voice by comparing the voice with a prestored voice signal of the user.

5. The electronic device according to claim 2 , wherein when the position of the user does not match the position of the sound source, the processor is further configured to increase a threshold for executing the command included in the voice by comparing the voice with a prestored voice signal of the user.

6. The electronic device according to claim 2 , wherein when the position of the user does not match the position of the sound source, the processor is further configured not to execute the command.

7. The electronic device according to claim 1 , wherein after determining to execute the command, the processor is further configured to transmit information related to execution of the command to at least one external electronic device.

8. The electronic device according to claim 1 , wherein the processor is further configured to:

receive information related to execution of the command from at least one external electronic device, and

determine whether to execute the command based on the received information.

9. The electronic device according to claim 1 , wherein the processor is further configured to:

when the position of the sound source is not included in the first zone, identify whether the command is included in the voice, and

when the command is included in the voice, execute a function corresponding to the command.

10. The electronic device according to claim 1 , wherein the command includes a command for waking up the electronic device.

11. A method of operating an electronic device, the method comprising:

identifying a position of a sound source based on a voice received through a plurality of microphones included in the electronic device;

identifying whether the position of the sound source is included in a first zone between the electronic device and an access point wirelessly connected with the electronic device, wherein the first zone includes a path through which a communication signal is transmitted from the access point to the electronic device;

identifying whether a position of a user is included in the first zone based on a comparison between the communication signal received from the access point and a preset communication signal stored in the electronic device, when the position of the sound source is included in the first zone, wherein when the user is in the first zone, the communication signal does not correspond to the preset communication signal due to a user's interference;

based on identifying that the position of the user is included in the first zone, determining to execute a command included in the voice; and

based on identifying that the position of the user is not included in the first zone, determine to refrain from executing the command included in the voice.

12. The method according to claim 11 , further comprising:

identifying whether the voice has been uttered by the user by comparing the position of the user with the position of the sound source.

13. The method according to claim 12 , wherein determining whether to execute the command included in the voice comprises:

when the position of the user matches the position of the sound source, determining to execute the command by comparing the voice with a prestored voice signal of the user.

14. The method according to claim 12 , further comprising:

when the position of the user matches the position of the sound source, decreasing a threshold for executing the command included in the voice by comparing the voice with a prestored voice signal of the user.

15. The method according to claim 12 , further comprising:

when the position of the user does not match the position of the sound source, increasing a threshold for executing the command included in the voice by comparing the voice with a prestored voice signal of the user.
