Inferring semantic label(s) for assistant device(s) based on device-specific signal(s)

A method implemented by one or more processors, the method comprising:

• identifying, from among a plurality of assistant devices in an ecosystem, a given assistant device;
• obtaining one or more device-specific signals that are associated with the given assistant device, the one or more device-specific signals being generated or received by the given assistant device, wherein one or more of the device-specific signals comprise at least a plurality of queries or commands previously received at the given assistant device;
• processing one or more of the device-specific signals to generate one or more candidate semantic labels for the given assistant device, wherein processing one or more of the device-specific signals to generate one or more of the candidate semantic labels for the given assistant device comprises:
• processing the plurality of queries or commands previously received at the given assistant device to generate one or more of the candidate semantic labels;
• generating, based on one or more of the candidate semantic labels, a prompt to solicit a selection of a given semantic label from a user of a client device, the selection being from among one or more of the candidate semantic labels;
• causing the prompt to be rendered at the client device of the user;
• and
• in response to receiving the selection of the given semantic label responsive to the prompt, assigning, in a device topology representation of the ecosystem, the given semantic label to the given assistant device.

A method implemented by one or more processors, the method comprising:

• identifying, from among a plurality of assistant devices in an ecosystem, a given assistant device;
• obtaining one or more device-specific signals that are associated with the given assistant device, the one or more device-specific signals being generated or received by the given assistant device, wherein one or more of the device-specific signals comprise at least a plurality of queries or commands previously received at the given assistant device;
• determining, based on one or more of the device-specific signals, a given semantic label for the given assistant device, wherein determining the given semantic label for the given assistant device is based on at least the plurality of queries or commands previously received at the given assistant device;
• assigning, in a device topology representation of the ecosystem, the given semantic label to the given assistant device;
• and
• subsequent to assigning the given semantic label to the given assistant device in the device topology representation of the ecosystem:
• receiving, via one or more respective microphones of one of the plurality of assistant devices in the ecosystem, and from a user associated with the ecosystem, audio data corresponding to a spoken utterance, the spoken utterance including an additional query or command;
• processing the audio data corresponding to the spoken utterance to determine a semantic property of the query or command;
• determining that the semantic property of the query or command matches the given semantic label assigned to the given assistant device;
• and
• in response to determining that the semantic property of the query or command matches the given semantic label assigned to the given assistant device, causing the given assistant device to satisfy the query or command.
