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.

-20. (canceled)
A computer-implemented method, comprising:
- capturing, by a first device, first audio representing a first spoken input by a first user;
- determining, by the first device, first audio data representing the first audio;
- causing speech processing to be performed using the first audio data;
- determining a second device associated with the first device is to capture further audio corresponding to further spoken inputs by the first user;
- capturing, by a second device, second audio representing a second spoken input by the first user;
- determining, by the second device, second audio data representing the second audio;
- and
- causing speech processing to be performed using the second audio data.
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:
- capture, by a first device, first audio representing a first spoken input by a first user;
- determine, by the first device, first audio data representing the first audio;
- cause speech processing to be performed using the first audio data;
- determine a second device associated with the first device is to capture further audio corresponding to further spoken inputs by the first user;
- capture, by a second device, second audio representing a second spoken input by the first user;
- determine, by the second device, second audio data representing the second audio;
- and
- cause speech processing to be performed using the second audio data.
