Claim 15:
16. A non-transitory computer-readable storage medium storing computer-readable instructions that, when executed by a first computing device, cause the computer to perform a method, comprising:
receiving, at the first computing device, the first computing device being configured to respond to voice commands that are preceded by a predefined hotword, audio data that corresponds to an utterance of the predefined hotword followed by a voice command;
determining, by the first computing device, that the audio data includes the predefined hotword;
calculating, by the first computing device and in response to determining that the audio data includes the predefined hotword, a first score reflecting a loudness of the audio data received at the first computing device;
activating, by the first computing device, a listening mode lasting for a duration of a delay period, the duration of the delay period being based on the loudness of the audio data received at the first computing device;
receiving, by the first computing device and via radio signals from a second computing device configured to respond to voice commands that are preceded by the predefined hotword, the first computing device and the second computing device sharing a same radio signal network, a second score reflecting a loudness of audio data received at the second computing device, the audio data received at the second computing device corresponding to the utterance of the predefined hotword followed by the voice command; and
processing, by the first computing device and when the first score is greater than the second score, at least a portion of the audio data using an automated speech recognizer.
