Abstract

Systems and methods for transitioning an electronic device from a power conservation state to a powered state based on detected sounds and an analysis of the detected sound are disclosed.

Claims

1. An electronic device comprising:

a sensor configured to detect a sound and generate a sound signal corresponding to the sound;

a communications module configured to determine that the sound signal is indicative of a wake-up phrase to a predetermined probability threshold level, and further configured to transmit a wake-up inquiry request based at least in part on the determining, and to receive a wake-up signal in response to the wake-up inquiry request; and

a platform module configured to transition from a first power state to a second power state based at least in part on the received wake-up signal.

2. The electronic device of claim 1, wherein the communications module is further configured to perform sampling of the sound signal.

3. The electronic device of claim 1, wherein the communications module further includes one or more communication processors configured to generate a filtered sound signal corresponding to the sound signal.

4. The electronic device of claim 3, wherein generating the filtered sound signal comprises at least one of:

(i) low pass filtering the sound signal;

(ii) high pass filtering the sound signal;

(iii) band pass filtering of the sound signal;

(iv) anti-alias filtering of the sound signal;

or (v) spectral equalization of the sound signal.

5. The electronic device of claim 1, wherein the sensor comprises an audio sensor or a microphone.

6. The electronic device of claim 1, wherein the communications module is further configured to generate the wake-up inquiry request.

7. The electronic device of claim 1, further comprising a filter configured to process the sound signal and determine that the sound signal is indicative of a wake-up phrase to a predetermined probability threshold level.

8. The electronic device of claim 1, wherein determining that the sound signal is indicative of a wake-up phrase to a predetermined probability threshold level further comprises at least one of:

(i) spectral analysis of the sound signal;

(ii) temporal analysis of the sound signal;

(ii) analysis of audio parameters associated with the sound signal.

9. The electronic device of claim 1 where the wake-up inquiry request comprises at least one of:

the sound signal or an identification of the electronic device.

10. The electronic device of claim 1, wherein the wake-up signal is received from a recognition server.

11. A method of waking an electronic device from a power conservation mode comprising:

generating a sound signal based at least in part on a detected sound;

verifying that the sound signal passes an input threshold;

transmitting the sound signal to a recognition server; and

transitioning the electronic device to a full power state upon receipt of a wake-up signal from the recognition server.

12. The method of claim 11, further comprising filtering the sound signal to generate a filtered sound signal.

13. The method of claim 12, wherein filtering the sound signal comprises one of:

(i) modifying the amplitude of the sound signal;

(ii) modifying the spectrum of the sound signal;

(iii) modifying one or more frequencies of the sound signal;

or (iv) performing spectral equalization of the sound signal.

14. The method of claim 11, wherein verifying that the sound signal passes an input threshold comprises comparing the sound signal to a sound signal template corresponding to a wake-up phrase.

15. The method of claim 11, wherein transitioning the electronic device to a full power state comprises waking up one or more processors associated with the electronic device from a stand-by state.

16. At least one computer-readable medium comprising computer-executable instructions that, when executed by one or more processors, executes a method comprising:

receiving a wake-up inquiry request from an electronic device in stand-by mode;

identifying a sound signal based at least in part on the wake-up inquiry request;

determining based at least in part on the sound signal that the sound signal is indicative of a wake-up phrase; and

sending a wake-up signal to the electronic device, responsive to determining that the sound signal is indicative of the wake-up phrase.

17. The computer-readable medium of claim 16, wherein determining that the sound signal is indicative of a wake-up phrase comprises at least one of:

(i) spectral analysis of the sound signal;

(ii) temporal analysis of the sound signal;

(ii) analysis of audio parameters associated with the sound signal.

18. The computer-readable medium of claim 16, wherein the method further includes transmitting statistics associated with the electronic device to the electronic device.

19. The computer-readable medium of claim 16, wherein identifying a sound signal based at least in part on the wake-up inquiry request comprises parsing one or more data packets associated with the wake-up inquiry request.

20. A system, comprising:

at least one memory that stores computer-executable instructions;

at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to;

receive a wake-up inquiry request from an electronic device in stand-by mode;

identify a sound signal based at least in part on the wake-up inquiry request;

determine based at least in part on the sound signal that the sound signal is indicative of a wake-up phrase; and

transmit a wake-up signal to the electronic device, responsive to determining that the sound signal is indicative of the wake-up phrase.

21. The system of claim 20, wherein the at least one processor is further configured to log statistics related to the electronic device.

22. The system of claim 21, wherein the at least one processor is further configured to transmit statistics log to the electronic device.
