Abstract:
Techniques for capturing spoken user inputs while a device is prevented from capturing such spoken user inputs are described. When a first device has a status representing it is unbeneficial for the first device to perform wakeword detection, a second device (e.g. a vehicle) may perform wakeword detection on behalf of the first device. The second device may be unable to send audio data, representing a spoken user input, to a speech processing system. In such an example, the second device may send the audio data to a third device, which may send the audio data to the speech processing system.
