Claim 16:
17. A first assistant-enabled device (AED) comprising:
data processing hardware; and
memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
receiving an assignment instruction assigning a group hotword to a selected group of AEDs associated with a user, the selected group of AEDs comprising the first AED and one or more other AEDs, each AED in the selected group of AEDs configured to run a hotword detection model trained to detect a presence of the group hotword in streaming audio without performing speech recognition and wake-up from a low-power state when the group hotword is detected in streaming audio by at least one of the AEDs in the selected group of AEDs, wherein other AEDs associated with the user that are not in the selected group of AEDs are configured to not wake-up from a low-power state when the group hotword is detected in the streaming audio by the at least one of the AEDs in the selected group of AEDs;
receiving audio data corresponding to an utterance spoken by the user, the audio data comprising a the group hotword and query specifying an operation to perform;
detecting, using the hotword detection model running on the first AED, the group hotword in the audio data without performing speech recognition processing on the audio data; and
in response to detecting the group hotword in the audio data:
triggering the first AED to wake-up from the low-power state; and
without performing speech recognition processing on the audio data, invoking, by the data processing hardware, each other AED in the selected group of AEDs that did not detect the group hotword in the audio data to wake-up from the low-power state and collaborate with all the AEDs in the selected group of AEDs to fulfill performance of the operation specified by the query; and
executing a collaboration routine to cause the first AED and each other AED in the selected group of AEDs to collaborate with one another to fulfill performance of the operation specified by the query.
