Classification: CPC G | IPC G

Claim 4:
5. A method, comprising:
receiving first audio data representing a first spoken user input;
generating first feature data representing first speech characteristics of the first spoken user input, the first feature data being unassociated with specific user profile data;
determining 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;
determining a first similarity value between the first feature data and the first stored feature data;
determining the first audio data comprises a first number of speech frames;
determining the first number of speech frames satisfies a threshold number of speech frames;
generating, 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;
receiving, after generating the first user recognition feature data, second audio data representing a third spoken user input;
generating second feature data representing third speech characteristics of the third spoken user input;
determining the second feature data corresponds to the first user recognition feature data;
determining, 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;
determining, using the system usage data, an action responsive to the third spoken user input; and
performing the action responsive to the third spoken user input.
