1. A hearing aid, comprising:
neural network circuitry configured to implement a neural network system comprising at least a first neural network and a second neural network operating in parallel; and
control circuitry configured to control the neural network system to:
reset one or more states of the first neural network at a first time;
receive a first input audio signal at a second time later than the first time;
process the first input audio signal using the first neural network to produce a first output and using the second neural network to produce a second output;
combine the first output and the second output using a first weight for the first output and a second weight for the second output, wherein the second weight is greater than the first weight;
receive a second input audio signal at a third time later than the second time;
process the second input audio signal using the first neural network to produce a third output and using the second neural network to produce a fourth output;
combine the third output and the fourth output using a third weight for the third output and a fourth weight for the fourth output, wherein the third weight is greater than the first weight; and
reset one or more states of the second neural network at a fourth time later than the third time.
