Claim 30:
31. 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 prior audio data spoken by a user and corresponding to a command for a digital assistant to perform a long-standing action on two or more assistant-enabled devices (AEDs) associated with the user, the digital assistant configured to automatically create a group hotword for use in follow-up queries that pertain to the long-standing action,
receiving the group hotword automatically created by the digital assistant as an assignment instruction that assigns the group hotword to a selected group of AEDs that comprises the two or more AEDs performing the long-standing action, 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;
receiving, at the data processing hardware, audio data corresponding to an utterance spoken by the user, the audio data comprising a query specifying an operation to perform;
detecting, by the data processing hardware, using the hotword detection model, the group hotword in the audio data; and
in response to detecting the group hotword in the audio data:
triggering, by the data processing hardware, the first AED to wake-up from the low-power state; and
executing, by the data processing hardware, 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.
