Abstract

A method includes identifying an active state of a headset interface of a device. A signal generated by a microphone of the device is monitored to identify an alert trigger not initiated by a user of the device. Operation of the headset interface is interrupted responsive to identifying the alert trigger. A device includes a microphone, a headset interface, and a processor coupled to the microphone and the headset interface. The processor is to identify an active state of the headset interface, monitor a signal generated by the microphone to identify an alert trigger not initiated by a user of the device, and interrupt operation of the headset interface responsive to identifying the alert trigger.

First claim

What is claimed is:

1. A method comprising:
identifying an active state of a headset interface of a device;
monitoring a signal generated by a microphone of the device to identify an alert trigger not initiated by a user of the device, wherein monitoring the signal further comprises identifying an external human voice signal, executing device commands in the external human voice signal responsive to the external human voice signal being associated with the user, and identifying the alert trigger responsive to the external human voice signal not being associated with the user; and
interrupting operation of the headset interface responsive to identifying the alert trigger.

2. The method of claim 1 , wherein interrupting operation of the headset interface comprises disabling the headset interface.

3. The method of claim 1 , wherein interrupting operation of the headset interface comprises pausing an application on the device communicating over the headset interface.

4. The method of claim 1 , wherein interrupting operation of the headset interface comprises communicating an alert audio signal over the headset interface.

5. The method of claim 1 , wherein interrupting operation of the headset interface comprises communicating a signal from the microphone over the headset interface.

6. The method of claim 1 , wherein interrupting operation of the headset interface comprises communicating an audio sample including the alert trigger over the headset interface.

7. The method of claim 1 , wherein monitoring the signal generated by the microphone of the device to identify the alert trigger comprises identifying an alert trigger phrase.

8. The method of claim 1 , wherein identifying the alert trigger phrase comprises identifying that the alert trigger phrase was not spoken by the user.

9. The method of claim 1 , wherein the headset interface comprises a wireless headset interface.

10. A device, comprising:
a microphone;
a headset interface; and
a processor coupled to the microphone and the headset interface, wherein the processor is to identify an active state of a headset interface, monitor a signal generated by the microphone to identify an alert trigger not initiated by a user of the device, identify an external human voice signal, execute device commands in the external human voice signal responsive to the external human voice signal being associated with the user, identify the alert trigger responsive to the external human voice signal not being associated with the user, and interrupt operation of the headset interface responsive to identifying the alert trigger.

11. The device of claim 10 , wherein the processor is to interrupt operation of the headset interface by disabling the headset interface.

12. The device of claim 10 , wherein the processor is to interrupt operation of the headset interface by pausing an application on the device communicating over the headset interface.

13. The device of claim 10 , wherein the processor is to interrupt operation of the headset interface by communicating an alert audio signal over the headset interface.

14. The device of claim 10 , wherein the processor is to interrupt operation of the headset interface by communicating a signal from the microphone over the headset interface.

15. The device of claim 10 , wherein the processor is to interrupt operation of the headset interface by communicating an audio sample including the alert trigger over the headset interface.

16. The device of claim 10 , wherein the processor is to identify an alert trigger phrase.

17. The device of claim 10 , wherein the processor is to identify that the alert trigger phrase was not spoken by the user.

18. The device of claim 10 , wherein the headset interface comprises a wireless headset interface.
