Abstract: A system may be configured to receive audio data input and determine whether the audio data corresponds to an acoustic event defined by an acoustic event profile. The system may be further configured to detect an ongoing acoustic event corresponding to multiple occurrences of an acoustic event type and, in response, execute a set of actions. The execution of the routine may be based on conditions corresponding to the ongoing acoustic event. The system may be configured to evaluate the occurrences based on the conditions of the ongoing acoustic event including whether the occurrences occur within a timer period, the relative time between occurrences, and whether at least one occurrence is detected within different portions of the time period. The acoustic event profile may be associated with a user profile. The system may execute a routine that sends a notification or directs a device to perform an action.

Abstract: A system may be configured to detect custom acoustic events, where the system generates an acoustic event profile for the custom acoustic event based on a natural language description provided by a user and using an audio sample of the described acoustic event. For example, the user may describe the custom acoustic event as “dog bark.” The system may ask the user questions to refine the description (e.g., dog breed, dog gender, age, etc.). Using an audio sample of the refined description, the system may then determine that audio captured in the user's environment is a potential sample of the custom acoustic event. Such captured audio may be presented to the user for confirmation, and then may be used to detect future occurrences of the custom acoustic event in the user's environment.
