Abstract: Systems and techniques are provided for processing one or more audio samples. For example, a process can include receiving one or more audio samples in a first audio frame and determining, using a first keyword detection model, a first keyword detection score for the first audio frame. One or more audio samples can be received in additional audio frames. Based on the first keyword detection score exceeding a first threshold, the first keyword detection model can be used to determine a keyword detection score for each audio frame of the additional audio frames. The respective keyword detection score for each audio frame of the additional audio frames can be compared to a second threshold that is greater than the first threshold. Based on the respective keyword detection score exceeding the second threshold, using a second keyword detection model to process the first audio frame and the additional audio frames can be skipped.

Abstract: A device includes a processor configured to receive a signal from a feedback microphone of an earphone. The processor is also configured to determine, based on a change over time of sound reflection characteristics represented in the received signal, a condition corresponding to ear wax buildup or water in an ear canal.
