Automatically Monitoring for Voice Input Based on Context
First Claim
1. A computer-implemented method comprising:
- detecting a context associated with a mobile computing device, the context indicating that the mobile computing device is traveling in a vehicle based at least in part on a calculated speed of the mobile computing device;
determining, based on the context, to switch the mobile computing device from a first mode of operation, during which the mobile computing device does not monitor ambient sounds for voice input that indicates a request to perform an operation, to a second mode of operation during which the mobile computing device monitors ambient sounds for voice input that indicates a request to perform an operation;
in response to determining to switch to the second mode of operation, activating one or more microphones and a speech analysis system associated with the mobile computing device; and
providing output using the mobile computing device, the output being responsive to voice input that is detected in a stream of audio data and that indicates a request to perform an operation.

Abstract
In one implementation, a computer-implemented method includes detecting a current context associated with a mobile computing device and determining, based on the current context, whether to switch the mobile computing device from a current mode of operation to a second mode of operation during which the mobile computing device monitors ambient sounds for voice input that indicates a request to perform an operation. The method can further include, in response to determining whether to switch to the second mode of operation, activating one or more microphones and a speech analysis subsystem associated with the mobile computing device so that the mobile computing device receives a stream of audio data. The method can also include providing output on the mobile computing device that is responsive to voice input that is detected in the stream of audio data and that indicates a request to perform an operation.

13. A system for automatically monitoring for voice input, the system comprising:
-
a mobile computing device; one or more microphones that receive ambient audio signals and provide electronic audio data to the mobile computing device; a context determination unit that detects a context associated with the mobile computing device, the context indicating that the mobile computing device is traveling in a vehicle based at least in part on a calculated speed of the mobile computing device; a mode selection unit that determines, based on the context determined by the context determination unit, to switch the mobile computing device from a first mode of operation, during which the mobile computing device does not monitor ambient sounds for voice input that indicates a request to perform an operation, to a second mode of operation during which the mobile computing device monitors ambient sounds for voice input that indicates a request to perform an operation; an input system that activates the one or more microphones and a speech analysis system associated with the mobile computing device in response to determining to switch to the second mode of operation; and an output that provides output via the mobile computing device, the output being responsive to voice input that is detected in the stream of audio data and that indicates a request to perform an operation. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
