Abstract

An electronic apparatus includes a voice acquirer which receives a first voice, a voice processor which processes a voice signal, a communication unit which communicates with at least one external electronic apparatus and receives information on at least one second voice, and a controller which determines whether the first voice is a user'"'"'s command based on the information on at least one second voice transmitted by the communication unit, and if the first voice is not the user'"'"'s command, does not perform an operation according to the first voice.

Claims

1. An electric apparatus comprising:

a microphone configured to receive an input sound including at least one of a voice input of a user ad a first sound output of at least one external electronic apparatus in vicinity of the electronic apparatus to generate a voice signal corresponding to the input sound;

a first communication circuit configured to communicate with the at least one external electronic apparatus, the voice data being information about the first sound output and in addition to the first sound output that is exchanged between the at least one external electronic apparatus and the first communication circuit while the first sound output is being received by the microphone;

a voice processor configured to process the voice signal generated by the microphone and the voice data received from the first communication circuit; and

a controller configured;

to compare the input sound of the voice signal with the voice data of the first sound output; and

in response to determining that there is no predetermined similarity between the input sound and the voice data, to control to recognize the voice input included in the input sound, and to perform an operation according to a user'"'"'s command corresponding to the recognized voice input.

2. The electronic apparatus according to claim 1, further comprising a second communication circuit configured to perform a voice call,

wherein the controller is further configured to control the first communication circuit to transmit voice data of the voice input of the user to the at least one external electronic apparatus while the voice call is being performed by the second communication circuit.

3. The electronic apparatus according to claim 1, further comprising a display configured to display an image, and a speaker configured to output a second sound output corresponding to the image displayed on the display, wherein the controller is further configured to control the first communication circuit to transmit voice data of the second sound output to the at least one external electronic apparatus.

4. The electronic apparatus according to claim 1, wherein the controller is further configured to determine whether the command corresponding to the voice input of the user comprises a first command granting a control right to control the at least one external electronic apparatus to the controller, and to control the first communication circuit to transmit information to notify that the controller has obtained the control right to the at least one external electronic apparatus which the controller has obtained the control right of in response to the voice input of the user comprising the first command.

5. The electronic apparatus according to claim 4, wherein the controller which has obtained the control right is further configured to determine whether the command corresponding to the voice input comprises a second command with respect to the at least one external electronic apparatus which the controller has obtained the control right of and to control the first communication circuit to transmit the second command to the at least one external electronic apparatus.

6. The electronic apparatus according to claim 1, wherein the controller is further configured not to perform an operation according to the command corresponding to the voice input of the user in response to receiving information to notify that one of the at least one external electronic apparatus has obtained the control right to control the electronic apparatus.

7. The electronic apparatus according to claim 1, wherein the controller is further configured to determine a first distance between the user and the electronic apparatus and a second distance between the user and the at least one external electronic apparatus, to determine the command corresponding to the voice of the user using the first distance and the second distance.

8. The electronic apparatus according to claim 1, wherein the controller is further configured to determine an angle between the user and the electronic apparatus and to determine the command corresponding to the voice input of the user based on the angle between the user and the electronic apparatus.

9. A control method of an electronic apparatus comprising:

by a microphone, receiving an input sound including at least one of a voice input of a user and a first sound output of at least one external electronic apparatus in vicinity of the electronic apparatus to generate a voice signal corresponding to the input sound;

by a first communication circuit, receiving voice data of the first sound output, from the at least one external electronic apparatus, the voice data being information about the first sound output and in addition to the first sound output that is exchanged between the at least one external electronic apparatus and the first communication circuit while the first sound output is being received by the microphone;

by a controller, comparing the input sound of the voice signal with the voice data of the first sound output; and

by the controller, in response to determining that there is no predetermined similarity between the input sound and the voice data, recognizing the voice input included in the input sound, and performing an operation according to a user'"'"'s command corresponding to the recognized voice input.

10. The control method according to claim 9, further comprising performing a voice call, and transmitting voice data of the voice input of the user to the at least one external electronic apparatus while the voice call is being performed.

11. The control method according to claim 9, further comprising displaying an image, and outputting a second output corresponding to the image;

and

transmitting voice data of the second sound output to the at least one external electronic apparatus.

12. The control method according to claim 9, further comprising determining whether the command corresponding to the voice input of the user comprises a first command granting a control right to control the at least one external electronic apparatus;

and

obtaining the control right and transmitting information to notify that the electronic apparatus has obtained the control right to the at least one external electronic apparatus which the electronic apparatus has obtained the control right of in response to the voice input comprising the first command.

13. The control method according to claim 12, further comprising determining whether the command corresponding to the voice input of the user comprises a second command with respect to the at least one external electronic apparatus which the electronic apparatus has obtained the control right of;

and

transmitting the second command to the at least one external electronic apparatus.

14. The control method according to claim 9, further comprising receiving information to notify that the at least one external electronic apparatus has obtained the control right to control the electronic apparatus;

and

not performing an operation according to the command corresponding to the voice input of the user.

15. The control method according to claim 9, further comprising, determining a first distance between the user and the electronic apparatus and a second distance between the user and the at least one external electronic apparatus, and determining the command corresponding to the voice input of the user based on the first distance and the second distance.

16. The control method according to claim 9, further comprising determining an angle between the user and the electronic apparatus and determining the command corresponding to the voice input of the user based on the determined angle between the user and the electronic apparatus.
