Abstract

Disclosed herein is an electronic device. The electronic device according to an embodiment of the present disclosure includes an input unit configured to receive a speech input including a wakeup word and a command word from a sound source, a communication unit configured to communicate with one or more other electronic devices, an artificial intelligence unit configured to obtain a degree of recognition of the wakeup word in the electronic device, receive a degree of recognition of the wakeup word in each of the one or more other electronic devices, and perform a function corresponding to the command word when the electronic device has a highest priority based on the degree of recognition of the wakeup word in the electronic device and the degree of recognition of the wakeup word in each of the one or more other electronic devices, wherein the degree of recognition of the wakeup word in the electronic device is obtained based on at least one of a score of the wakeup word or location information of the sound source, in the electronic device.

Claims

1. An electronic device comprising:

an input interface configured to receive a speech input including a wakeup word and a command word from a sound source;

a communication interface configured to communicate with one or more other electronic devices; and

an artificial intelligence interface configured to obtain a degree of recognition of the wakeup word in the electronic device, receive a degree of recognition of the wakeup word in each of the one or more other electronic devices, and perform a function corresponding to the command word when the electronic device has a highest priority based on the degree of recognition of the wakeup word in the electronic device and the degree of recognition of the wakeup word in each of the one or more other electronic devices,

wherein the degree of recognition of the wakeup word in the electronic device is obtained based on at least one of a score of the wakeup word or location information of the sound source, in the electronic device.

2. The electronic device of claim 1, wherein the electronic device and the one or more other electronic devices are called by a same wakeup word.

3. The electronic device of claim 1, wherein the artificial intelligence interface is configured to obtain a priority of the electronic device based on the score of the wakeup word in the electronic device and the score of the wakeup word in each of the one or more other electronic devices, and perform a function correspond to the command word when the electronic device has the highest priority.

4. The electronic device of claim 1, wherein the artificial intelligence interface is configured to obtain a priority of the electronic device based on location information of the sound source in the electronic device and location information of the sound source in each of the one or more other electronic devices, and perform a function correspond to the command word when the electronic device has a highest priority.

5. The electronic device of claim 1, wherein the artificial intelligence interface is configured to obtain a priority of the electronic device based on the degree of recognition of the wakeup word in the electronic device and the degree of recognition of the wakeup word in each of the one or more other electronic devices, and perform a function correspond to the command word when the electronic device has a highest priority,

wherein the degree of recognition of the wakeup word in the electronic device is obtained based on at the score of the wakeup word and the location information of the sound source in the electronic device, and

wherein the degree of recognition of the wakeup word in each of the one or more other electronic devices is obtained based on at the score of the wakeup word and the location information of the sound source each of the one or more other electronic devices.

6. The electronic device of claim 1, wherein the artificial intelligence interface is configured to determine whether the function corresponding to the command word is a function provided by the electronic device when the electronic device has the highest priority, and perform the function corresponding to the command word when the function corresponding to the command word is the function provided by the electronic device.

7. The electronic device of claim 1, wherein the artificial intelligence interface is configured to determine whether the function corresponding to the command word is a function provided by the electronic device when the electronic device has the highest priority, and transmit a command for performing the function corresponding to the command word to an electronic device having a next highest priority when the function corresponding to the command word is not the function provided by the electronic device.

8. An electronic device comprising:

an input interface configured to receive a speech input including a wakeup word and a speech input including a command word from a sound source;

a communication interface configured to communicate with one or more other electronic devices and a server; and

an artificial intelligence interface configured to obtain a degree of recognition of the wakeup word in the electronic device, receive a degree of recognition of the wakeup word in each of the one or more other electronic devices, and transmit command word information corresponding to the speech input including the command word to the server when the electronic device has a priority higher than or equal to a predetermined priority based on the degree of recognition of the wakeup word in the electronic device and the degree of recognition of the wakeup word in each of the one or more other electronic devices,

wherein the degree of recognition of the wakeup word in the electronic device is obtained based on at least one of a score of the wakeup word or location information of the sound source in the electronic device.

9. The electronic device of claim 8, wherein the artificial intelligence interface is configured to transmit the command word information to the server when the electronic device has a highest priority and perform a function corresponding to the command word when a command for performing the function corresponding to the command word is received.

10. The electronic device of claim 8, wherein the artificial intelligence interface is configured to transmit the command word information and priority information of the electronic device to the server and perform a function corresponding to the command word when a command for performing the function corresponding to the command word is received.

11. The electronic device of claim 8, wherein the artificial intelligence interface is configured to transmit the command word information to the server when the electronic device has a highest priority and perform a function corresponding to the command word when a command for performing the function corresponding to the command word is received and the function corresponding to the command word is a function provided by the electronic device.

12. A server comprising:

a communication interface configured to communicate with a plurality of electronic devices; and

a controller configured to receive command word information corresponding to a speech input of a user from one or more electronic devices, recognize a command word included in the speech input based on the command word information, obtain a function corresponding to the command word and transmit a command for performing the function corresponding to the command word to one of the one or more electronic devices.

13. The sever of claim 12, wherein the controller is configured to receive the command word information from a first electronic device, determine whether the function corresponding to the command word is a function provided by the first electronic device, and transmit a command for performing the function corresponding to the command word to the first electronic device when the function corresponding to the command word is a function provided by the first electronic device.
