Classification: CPC G | IPC G

Claim 8:
9. An electronic device comprising:
a neural network pipeline having the form of a finite state machine, the finite state machine having a first state and a second state,
wherein a first neural network of the neural network pipeline operates continuously to identify a keyword in an audio data in the first state, a second neural network of the neural network pipeline being inactive during the first state, the first neural network configured to, in the first state:
analyze the audio data, the first neural network having a first processing workload, and
detect the keyword from the audio data, and

wherein the finite state machine is configured to transition from the first state to the second state in response to the first neural network identifying the keyword, wherein the first neural network is deactivated during the second state, the second neural network configured to, in the second state:
analyze the audio data using the second neural network, the second neural network having a second processing workload that is greater than the first processing workload, and
detect a vocal command word using the second neural network.
