Abstract

An electronic device is provided. The electronic device includes a microphone configured to receive a voice, communication circuitry configured to communicate with an external electronic device, a memory, and a processor operatively connected to the microphone, the communication circuitry, and the memory. The memory stores instructions that, when executed by the processor, cause the electronic device to perform voice recognition for voice data corresponding to the voice, and determine whether to perform voiceprint recognition for the voice data based on whether a first expression is included in a result of the voice recognition.

First claim

What is claimed is:

1. An electronic device comprising:
a microphone configured to receive a voice;
communication circuitry configured to communicate with an external electronic device;
a memory; and
a processor operatively connected to the microphone, the communication circuitry, and the memory,
wherein the memory stores instructions that, when executed by processor, cause the electronic device to:
perform voice recognition for voice data corresponding to the voice;
determine an instruction and an object from a result of the voice recognition, wherein the instruction is an expression corresponding to a function performed by the electronic device, and the object is a target of the instruction;
determine a security level of the instruction extracted from the result of the voice recognition;
determine a security level of the object extracted from the result of the voice recognition;
determine whether to perform voiceprint recognition for the voice data based on whether the expression is corresponding to a first expression; and
after determining to perform voiceprint recognition, determine a sensitivity for the voiceprint recognition based on both: (a) the security level of the instruction, and (b) the security level of the object.

2. The electronic device of claim 1 , wherein the memory further stores instructions that, when executed by the processor, cause the electronic device to:
perform the voiceprint recognition for the voice data when the expression is corresponding to the first expression; and
perform the function corresponding to the first expression when the voice is a voice uttered by a specific user, based on a result of the voiceprint recognition.

3. The electronic device of claim 2 , wherein the memory further stores instructions that, when executed by the processor, cause the electronic device to:
transmit a signal corresponding to the function to the external electronic device through the communication circuitry.

4. The electronic device of claim 1 , wherein the memory further stores instructions that, when executed by the processor, cause the electronic device to:
acquire the voice data from the external electronic device through the communication circuitry.

5. The electronic device of claim 1 , wherein the memory further stores instructions that, when executed by the processor, cause the electronic device to:
determine a security level of a second expression when, in addition to the first expression, the second expression is included in the result of the voice recognition; and
adjust a sensitivity of the voiceprint recognition based on the security level of the second expression.

6. The electronic device of claim 5 , wherein the memory further stores instructions that, when executed by the processor, cause the electronic device to:
determine the security level of the second expression based on at least one of: user history information for the second expression, a monetary value of the object corresponding to the second expression, and location information of the object.

7. The electronic device of claim 1 , wherein the memory further stores instructions that, when executed by the processor, cause the electronic device to:
perform the voiceprint recognition for the voice data when the expression is corresponding to the first expression; and
provide a notification that an auxiliary authentication is required, based on a result of the voiceprint recognition when the auxiliary authentication for determining whether the voice is a voice uttered by a specific user is required.

8. The electronic device of claim 7 , wherein the memory further stores instructions that, when executed by the processor, cause the electronic device to:
acquire at least one of: fingerprint recognition, iris recognition, and password authentication information with the auxiliary authentication.

9. A voice input method for an electronic device, comprising:
acquiring voice data;
performing voice recognition for the voice data;
determining an instruction and an object from a result of the voice recognition, wherein the instruction is an expression corresponding to a function performed by the electronic device, and the object is a target of the instruction;
determining a security level of the instruction extracted from the result of the voice recognition;
determining a security level of the object extracted from the result of the voice recognition;
determining whether to perform voiceprint recognition for the voice data based on whether the expression is corresponding to a first expression; and
after determining to perform voiceprint recognition,
determining a sensitivity for the voiceprint recognition based on both: (a) the security level of the instruction, and (b) the security level of the object.

10. The voice input method of claim 9 , further comprising:
performing the voiceprint recognition for the voice data when the expression is corresponding to the first expression; and
performing the function corresponding to the first expression based on a result of the voiceprint recognition when the voice data is voice data corresponding to a voice by a specific user.

11. The voice input method of claim 10 , wherein the performing of the function includes:
transmitting a signal corresponding to the function to an external electronic device through communication circuitry.

12. The voice input method of claim 9 , wherein the acquiring of the voice data includes:
acquiring the voice data through a microphone and/or from an external electronic device through communication circuitry.

13. The voice input method of claim 9 , further comprising:
determining a security level of a second expression when, in addition to the first expression, the second expression is included in the result of the voice recognition; and
adjusting a sensitivity of the voiceprint recognition based on the security level of the second expression.

14. The voice input method of claim 13 , wherein the determining of the security level of the second expression includes:
determining the security level of the second expression based on at least one of: user history information for the second expression, a monetary value of the object corresponding to the second expression, and location information of the object.

15. The voice input method of claim 9 , further comprising:
performing the voiceprint recognition for the voice data when the expression is corresponding to the first expression; and
providing a notification that an auxiliary authentication is required, based on a performance result of the voiceprint recognition when the auxiliary authentication for determining whether the voice data is voice data corresponding to a voice uttered by a specific user is required.

16. The voice input method of claim 15 , further comprising:
acquiring at least one of: fingerprint recognition, iris recognition, and password authentication information with the auxiliary authentication.

17. A system comprising:
a communication interface comprising communication circuitry;
a processor electrically connected to the communication interface; and
a memory electrically connected to the processor,
wherein the memory stores instructions that, when executed by the processor, cause an electronic device to:
receive voice data including a request through the communication interface;
convert the voice data to text data;
determine whether the text data includes an instruction and an object, wherein the instruction is an expression corresponding to a function performed by the electronic device,
