Abstract: An audio processing path receives an audio signal from a microphone of an ear-wearable device and reproduces the audio signal at a receiver that is placed within an ear of a user. A deep neural network (DNN) is coupled to the audio processing path that performs speech enhancement on the audio signal. An audio feature detector is operable to detect an audio change via the processing path that triggers a change of state of the DNN. The change of state affects resource consumption by the DNN. The change of state is applied to the DNN, and the DNN performs the speech enhancement in the changed state.
