Classification: CPC G | IPC G

Claim 12:
13. A system, comprising:
at least one processor; and
at least one memory comprising instructions that, when executed by the at least one processor, cause the system to:
receive first audio data representing a first spoken user input;
generate first feature data representing first speech characteristics of the first spoken user input, the first feature data being unassociated with specific user profile data;
determine first stored feature data representing second speech characteristics of a second spoken user input, the first stored feature data being unassociated with specific user profile data;
determine a first similarity value between the first feature data and the first stored feature data;
determine the first audio data comprises a first number of speech frames;
determine the first number of speech frames satisfies a threshold number of speech frames;
generate, based at least in part on the first similarity value and the first number of speech frames satisfying the threshold number of speech frames, first user recognition feature data using the first feature data and the first stored feature data;
receive, after generating the first user recognition feature data, second audio data representing a third spoken user input;
generate second feature data representing third speech characteristics of the third spoken user input;
determine the second feature data corresponds to the first user recognition feature data;
determine, after determining the second feature data corresponds to the first user recognition feature data, system usage data associated with the first user recognition feature data, the system usage data representing at least first content output in response to at least one previous spoken user input corresponding to the first user recognition feature data, the system usage data and the first user recognition feature data being unassociated with specific user profile data;
determine, using the system usage data, an action responsive to the third spoken user input; and
perform the action responsive to the third spoken user input.
