Abstract

An electronic device and a method for recognizing a voice are provided. An operating method of the electronic device includes detecting, at least one of two or more first sensors disposed in a preset region, detecting an amount of charge transfer over a preset value, when detecting the amount of the charge transfer over the preset value, detecting, at one of two or more second sensors disposed in a preset distance from two or more microphones, an object in a preset distance; and collecting, at one of the two or more microphones, the one disposed in a preset distance from the second sensor detecting the object in the preset distance, a voice.

Claims

1. An operating method of an electronic device, the method comprising:

detecting, at least one of two or more first sensors disposed in a preset region, an amount of charge transfer over a preset value;

when the amount of the charge transfer is greater than the preset value, detecting, at one of two or more second sensors disposed in a preset distance from two or more microphones, an object in a preset distance from the electronic device; and

receiving a voice at one of the two or more microphones disposed in the preset distance from the second sensor detecting the object in the preset distance.

2. The operating method of claim 1, wherein the two or more first sensors operate while the electronic device is in a deep-sleep mode.

3. The operating method of claim 1, wherein the first sensor is a grip sensor.

4. The operating method of claim 1, wherein the second sensor is a proximity sensor.

5. The operating method of claim 1, further comprising:

when the at least one of the two or more first sensors detects the amount of the charge transfer greater than the preset value, operating the two or more second sensors.

6. The operating method of claim 1, further comprising:

when the one of the two or more second sensors detects the object, operating the two or more microphones.

7. The operating method of claim 1, wherein the one of the two or more microphones disposed in the preset distance from the second sensor detecting the object, primarily receives the voice.

8. The operating method of claim 1, wherein at least one microphone, other than the one microphone of the two or more microphones disposed in the preset distance from the second sensor detecting the object, primarily cancels noise.

9. The operating method of claim 1, further comprising:

analyzing the detected voice;

recognizing a command corresponding to the detected voice; and

performing an operation according to the recognized command.

10. The operating method of claim 1, further comprising:

determining whether at least one second sensor other than the second sensor disposed in the preset distance from the microphone receiving the voice detects an object in the preset distance from the electronic device.

11. The operating method of claim 10, further comprising:

when the at least one second sensor other than the second sensor disposed in the preset distance from the microphone receiving the voice detects the object, receiving the voice at the microphone disposed in the preset distance from the second sensor detecting the object.

12. An electronic device comprising:

two or more first sensors disposed in a preset region, wherein one of the first sensors detects an amount of charge transfer greater than a preset value;

two or more second sensors disposed in a preset distance from two or more microphones and detecting an object in a preset distance from the electronic device when the one first sensor detects the amount of the charge transfer greater than the preset value; and

two or more microphones, one of which is disposed in the preset distance from the second sensor detecting the object and receives a voice.

13. The electronic device of claim 12, wherein the two or more first sensors operate while the electronic device is in a deep-sleep mode.

14. The electronic device of claim 12, wherein the first sensor is a grip sensor.

15. The electronic device of claim 12, wherein the second sensor is a proximity sensor.

16. The electronic device of claim 12, wherein the two or more second sensors operate when the one first sensor detects the amount of the charge transfer greater than the preset value.

17. The electronic device of claim 12, wherein the two or more microphones operate when the one of the two or more second sensors detects the object.

18. The electronic device of claim 12, wherein the one of the two or more microphones disposed in the preset distance from the second sensor detecting the object, primarily receives the voice.

19. The electronic device of claim 12, wherein at least one microphone other than the one microphone of the two or more microphones disposed in the preset distance from the second sensor detecting the object, primarily cancels noise.

20. The electronic device of claim 12, further comprising:

a processor unit for analyzing the detected voice, for recognizing a command corresponding to the detected voice, and for performing an operation according to the recognized command.

21. The electronic device of claim 12, wherein at least one second sensor, other than the second sensor disposed in the preset distance from the microphone receiving the voice determines whether an object is detected in the preset distance from the electronic device.

22. The electronic device of claim 21, further comprising:

a microphone disposed in the preset distance from the second sensor for detecting the object and for receiving the voice.
