Digital Signal Processor-Based Continued Conversation

A system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware and storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising:
• based on providing a response to an initial query for output from an assistant-enabled device, instructing an always-on first processor of the data processing hardware to operate in a follow-on query detection mode and an active second processor of the data processing hardware to return to a sleep state;
• and
• while the always-on first processor operates in the follow-on query detection mode:
• receiving follow-on audio data captured by the assistant-enabled device;
• performing, using a speaker identification (SID) model executing on the always-on first processor, speaker verification on the follow-on audio data to determine the follow-on audio data comprises an utterance spoken by a same user that submitted the initial query to a digital assistant;
• and
• based on the follow-on audio data comprising the utterance spoken by the same user that spoke the initial query, initiating a wake-up process on the second processor to determine whether the utterance comprises a follow-on query directed toward the digital assistant.
