Electronic apparatus and control method thereof

1. An electronic apparatus, comprising:

a voice input interface comprising circuitry configured to receive a voice input; and

a processor configured to:

obtain predefined information including scores for a plurality of voice assistants with respect to each of a plurality of keywords,

based on a voice input being received through the voice input interface, obtain keywords of the voice input,

obtain association degrees for the plurality of voice assistants, wherein each of the association degrees is based on combining scores between the obtained keywords and respective voice assistant of the plurality of voice assistants in the predefined information,

select a voice assistant among the plurality of voice assistants based on the obtained association degrees, and

perform a function corresponding to the voice input based on the selected voice assistant.

2. The electronic apparatus of claim 1 , wherein the processor is configured to select the voice assistant among the plurality of voice assistants having a highest degree of association from among the obtained association degrees for the plurality of voice assistants.

3. The electronic apparatus of claim 1 , wherein the plurality of voice assistants are included in the electronic apparatus.

4. The electronic apparatus of claim 1 , wherein the predefined information is based on a use history of the electronic apparatus.

5. The electronic apparatus of claim 4 , wherein the use history includes information obtained by counting a processing history of each of the plurality of voice assistants for a predetermined keyword of user voice input.

6. The electronic apparatus of claim 1 , wherein the processor is configured to adjust the association degree of the selected voice assistant for the plurality of keywords based on selecting the voice assistant associated with the obtained plurality of keywords.

7. The electronic apparatus of claim 6 , wherein the processor is configured to:

identify satisfaction with a result of performed voice recognition, and

to increase or decrease the association degree of the selected voice assistant with the obtained plurality of keywords based on the identified satisfaction.

8. The electronic apparatus of claim 7 , wherein the processor is configured to add a first adjustment value to the association degree of the selected voice assistant based on an identification that the satisfaction is high, and to add a second adjustment value less than the first adjustment value to the association degree of the selected voice assistant based on an identification that the satisfaction is low to adjust the association degree of the selected voice assistant.

9. The electronic apparatus of claim 1 , wherein the predefined information includes information obtained based on a plurality of other voice inputs.

10. The electronic apparatus of claim 1 , wherein the processor is configured to control a display to display a UI guiding the selected voice assistant based on an identification that an amount of data of the predefined information is not greater than a threshold, and to perform voice recognition on a voice input in response to a selection through the UI of the selected voice assistant.

11. The electronic apparatus of claim 1 , wherein the processor is configured to control a display to display a UI guiding a result of voice recognition by each of the plurality of voice assistants based on an identification that an amount of data of the predefined information is not greater than a threshold, and to perform the result on any one of the voice assistants selected through the UI.

12. A method of controlling an electronic apparatus, the method comprising:

obtaining predefined information including scores for a plurality of voice assistants with a plurality of keywords;

based on a voice input received through a voice input interface comprising circuitry configured to receive the voice input, obtaining keywords of the voice input;

obtaining association degrees for the plurality of voice assistants, wherein each of the association degrees is based on combining scores between the obtained keywords and respective voice assistant of the plurality of voice assistants in the predefined information;

selecting a voice assistant among the plurality of voice assistants based on the obtained association degrees; and

performing a function corresponding to the voice input based on the selected voice assistant.

13. The method of claim 12 , wherein the voice assistant having a highest degree of association from among the obtained association degrees for the plurality of voice assistants is selected among the plurality of voice assistants.

14. The method of claim 12 , wherein the plurality of voice assistants are included in the electronic apparatus.

15. The method of claim 12 , wherein the predefined information is provided based on a use history of the electronic apparatus.

16. The method of claim 15 , wherein the use history includes information obtained by counting a processing history of each of the plurality of voice assistants for a predetermined keyword.

17. The method of claim 12 , further comprising:

adjusting the association degree of the selected voice assistant for the plurality of keywords based on selecting the voice assistant associated with the obtained plurality of keywords.

18. The method of claim 17 , wherein satisfaction with a result of performed voice recognition is identified, and

the association degree of the selected voice assistant with the obtained plurality of keywords increases and decreases based on the identified satisfaction.

19. The method of claim 18 , wherein a first adjustment value is added to the association degree of the selected voice assistant based on an identification that the satisfaction is high, and a second adjustment value less than the first adjustment value is added to the association degree of the selected voice assistant based on an identification that the satisfaction is low to adjust the association degree of the selected voice assistant.

20. The method of claim 12 , wherein the predefined information includes information obtained based on a plurality of other voice inputs.
