14. An electronic system, comprising: and at least one processor operable to: receive a first instance of audio data representing a first sound; determine that, within a temporal window, a plurality of additional instances of audio data representing the first sound are also received; determine a number of the instances of audio data representing the first sound that are received within the temporal window; determine that the number of instances is greater than a threshold value; based at least in part on a determination that the number of instances is greater than the threshold value, generate a first sound profile of the first sound; store the first sound profile; receive second audio data representing a second sound; generate a second sound profile of the second sound; determine that a similarity value of the second sound profile and the first sound profile is greater than a similarity threshold value; and based at least in part on a determination that the similarity value is greater than the similarity threshold value, refrain from performing at least some automated speech recognition processing for the second audio data.

The electronic system of claim 14 , wherein the at least one processor is separate from one or more user devices that generate the first audio data and the second audio data.
