Abstract

A method of performing a voice command function in an electronic device includes detecting voice of a user, acquiring one or more pieces of attribute information from the voice, and authenticating the user by comparing the attribute information with pre-stored authentic attribe information, using a recognition model. An electronic device includes a voice input module configured to detect a voice of a user, a first processor configured to acquire one or more pieces of attribute information from the voice and authenticate the user by comparing the attribute information with a recognition model, and a second processor configured to when the attribute information matches the recognition mode, activate the voice command function, receive a voice command of the user, and execute an application corresponding to the voice command. Other embodiments are also disclosed.

Claims

1. A method of performing a voice command function in an electronic device, the method comprising:

detecting voice of a user;

acquiring one or more pieces of attribute information from the voice; and

authenticating the user by comparing the attribute information with pre-stored authentic attribute information, using a recognition model.

2. The method of claim 1, further comprising, when the attributes information matches the recognition mode:

activating a voice command function;

receiving a voice command from the user; and

executing an application corresponding to the voice command.

3. The method of claim 2, wherein the authenticating the user is performed by a first processor and the executing the application corresponding to the voice command is performed by a second processor, different from the first processor.

4. The method of claim 2, wherein, when the attribute information matches the recognition model, the first processor is configured to generate a wake up signal and transmit the wake up signal to the second processor.

5. The method of claim 2, wherein the second processor is configured to receive the wake up signal and activate the voice command function.

6. The method of claim 1, wherein the one or more pieces of attribute information include at least one of a length, a size, a number of phonemes, and a length of phonemes of the voice.

7. The method of claim 1, wherein the recognition model is a speaker-dependent voice recognition model including the one or more pieces of attribute information.

8. The method of claim 1, wherein the detecting the voice comprises:

detecting a sound including the voice of the user;

measuring information on surrounding environment of the user, based on the sound; and

informing the user of the information on the surrounding environment.

9. An electronic device, comprising:

a voice input module configured to detect a voice of a user;

a first processor configured to;

acquire one or more pieces of attribute information from the voice and authenticate the user by comparing the attribute information with a recognition model; and

a second processor configured to;

when the attribute information matches the recognition mode, activate the voice command function,

receive a voice command of the user, and

execute an application corresponding to the voice command.

10. The electronic device of claim 9, wherein, when the attribute information matches the recognition model, the first processor is configured to generate a wake up signal and transmit the wake up signal to the second processor.

11. The electronic device of claim 10, wherein the second processor is configured to receive the wake up signal and activate the voice command function.

12. The electronic device of claim 9, wherein the one or more pieces of attribute information include at least one of a length, a size, a number of phonemes, and a length of phonemes of the voice.

13. The electronic device of claim 9, wherein the recognition model is a speaker-dependent voice recognition model including the one or more pieces of attribute information.

14. The electronic device of claim 9, wherein the first processor is configured to measure a noise level in surrounding environment of the user through the voice input module.

15. A computer-readable medium storing commands, when executed by one or more processors, causes the one or more processors to perform acts including:

detecting a voice of a user;

acquiring one or more pieces of attribute information from the voice; and

authenticating the user by comparing the attribute information with a recognition model.

16. The computer-readable medium of claim 15, wherein the commands further causes the one or more processors to perform acts including:

activating the voice command function;

receiving a voice command of the user; and

executing an application corresponding to the voice command.

17. The computer-readable medium of claim 15, wherein the second processor is configured to receive the wake up signal and activate the voice command function.

18. The computer-readable medium of claim 15, wherein the one or more pieces of attribute information include at least one of a length, a size, a number of phonemes, and a length of phonemes of the voice.

19. The computer-readable medium of claim 15, wherein the recognition model is a speaker-dependent voice recognition model including the one or more pieces of attribute information.

20. The computer-readable medium of claim 15, wherein, when the attribute information matches the recognition model, the first processor is configured to generate a wake up signal and transmit the wake up signal to the second processor.
