Abstract
Techniques for capturing spoken user inputs while a device is prevented from capturing such spoken user inputs are described. When a first device becomes incapable of capturing spoken user inputs intended for a system, a second device, for capturing such spoken user inputs, may be identified. The second device may be identified based on the second device being connected to a same vehicle computing system as the first device. The second device may be enabled to capture spoken user inputs, intended for the system, until the first device is again able to capture such spoken user inputs.
Claims17
A computer-implemented method, comprising:
- determining a first device is connected to a second device;
- receiving an indication based at least in part on a change of an operational status of the second device;
- in response to the indication and based at least in part on the first device being connected to the second device, disabling wakeword detection by the second device;
- and
- in response to the indication and based at least in part on the first device being connected to the second device, enabling wakeword detection by the first device.
A system comprising:
- at least one processor;
- and
- at least one memory comprising instructions that, when executed by the at least one processor, cause the system to:
- determine a first device is connected to a second device;
- receive an indication based at least in part on a change of an operational status of the second device;
- in response to the indication and based at least in part on the first device being connected to the second device, disabling wakeword detection by the second device;
- and
- in response to the indication and based at least in part on the first device being connected to the second device, enable wakeword detection by the first device.
