Abstract

An electronic apparatus and a control method are provided, including an input interface, a communication interface, a memory including at least one command, and at least one processor configured to control the electronic device and execute the at least one command to receive a user speech through the input interface, determine whether or not the user speech is a speech related to a task requiring user confirmation by analyzing the user speech, generate a question for the user confirmation when it is determined that the user speech is the speech related to the task requiring the user confirmation, and perform a task corresponding to the user speech when a user response corresponding to the question is input through the input interface. Embodiments may use an artificial intelligence model learned according to at least one of machine learning, a neural network, and a deep learning algorithm.

Claims

1. An electronic device comprising:

an input interface;

a communication interface;

a memory including at least one command; and

at least one processor connected to the input interface, the communication interface, and the memory and configured to control the electronic device,

wherein the at least one processor executes the at least one command to be configured to;

receive a user speech through the input interface,

identify whether or not the user speech is a speech related to a task requiring user confirmation by analyzing the user speech,

obtain a question for the user confirmation based on determination that the user speech is the speech related to the task requiring the user confirmation, and

perform a task corresponding to the user speech based on a user response corresponding to the question being inputted through the input interface.

2. The electronic device as claimed in claim 1, wherein the question is a question that is not related to the task corresponding to the user speech.

3. The electronic device as claimed in claim 1, wherein the at least one processor executes the at least one command to be further configured to:

identify a task related to the user speech and an entity for performing the task by analyzing the user speech,

obtain a security score of the user speech based on the identified task and entity, and

determine whether or not the user speech is the speech related to the task requiring the user confirmation based on the security score of the user speech.

4. The electronic device as claimed in claim 3, wherein the at least one processor executes the at least one command to be further configured to:

obtain the question on the basis of the security score based on determination that the user speech is the speech related to the task requiring the user confirmation based on the security score of the user speech.

5. The electronic device as claimed in claim 4, wherein the at least one processor executes the at least one command to be further configured to:

obtain a question having a low relevance to the task corresponding to the user speech as the security score becomes high.

6. The electronic device as claimed in claim 4, wherein the at least one processor executes the at least one command to be further configured to:

provide an authentication message for user authentication based on the security score being a threshold value or more.

7. The electronic device as claimed in claim 1, wherein the at least one processor executes the at least one command to be further configured to:

extract at least one of texts included in the user speech, and

obtain a question for inducing user utterance for the extracted at least one text.

8. The electronic device as claimed in claim 1, wherein the at least one processor executes the at least one command to be further configured to:

obtain speech feature information on a text distinguished from that of another user by analyzing a speech of a user using the electronic device, and

store the speech feature information in the memory.

9. The electronic device as claimed in claim 8, wherein the at least one processor executes the at least one command to be further configured to:

obtain a question including the stored text based on determination that the user speech is the speech related to the task requiring the user confirmation, and

perform the task corresponding to the user speech based on the speech feature information on the text being obtained in the user response.

10. The electronic device as claimed in claim 1, wherein the task requiring the user confirmation comprises at least one of a remittance task, a product purchase task, an email transmission task, a message transmission task, or a telephone call task.

11. A control method of an electronic device, comprising:

receiving a user speech;

identifying whether or not the user speech is a speech related to a task requiring user confirmation by analyzing the user speech;

obtaining a question for the user confirmation based on determination that the user speech is the speech related to the task requiring the user confirmation; and

performing a task corresponding to the user speech based on a user response corresponding to the question being inputted.

12. The control method as claimed in claim 11, wherein the question is a question that is not related to the task corresponding to the user speech.

13. The control method as claimed in claim 11, wherein the determining that the user speech is the speech related to the task requiring the user confirmation comprises:

identifying a task related to the user speech and an entity for performing the task by analyzing the user speech;

obtaining a security score of the user speech based on the identified task and entity; and

determining whether or not the user speech is the speech related to the task requiring the user confirmation based on the security score of the user speech.

14. The control method as claimed in claim 13,

wherein a question is generated on the basis of the security score, and

wherein the security score is based on the determination that the user speech is the speech related to the task requiring the user confirmation.

15. The control method as claimed in claim 14, wherein a question having a low relevance to the task corresponding to the user speech is generated as the security score becomes high.

16. The control method as claimed in claim 14, wherein an authentication message for user authentication is provided based on the security score being a threshold value or more.

17. The control method as claimed in claim 11, wherein at least one of texts included in the user speech is extracted and a question for inducing user utterance for the extracted at least one text is generated.

18. The control method as claimed in claim 11, further comprising:

obtaining speech feature information on a text distinguished from that of another user by analyzing a speech of a user using the electronic device; and

storing the speech feature information.

19. The control method as claimed in claim 18,

wherein a question including the stored text is generated based on determination that the user speech is the speech related to the task requiring the user confirmation, and

wherein the task corresponding to the user speech is performed based on the speech feature information on the text being obtained in the user response.

20. The control method as claimed in claim 11, wherein the task requiring the user confirmation comprises at least one of a remittance task, a product purchase task, an email transmission task, a message transmission task, or a telephone call task.
