摘要： A method of operating an audio monitoring system includes generating with a sound sensor audio data corresponding to a sound event generated by an object in a scene around the sound sensor, identifying with a processor a type and action of the object in the scene that generated the sound with reference to the audio data, generating with the processor a timestamp corresponding to a time of the detection of the sound event, and updating a scene state model corresponding to sound events generated by a plurality of objects in the scene with reference to the identified type of object, action taken by the object, and the timestamp. The method further includes identifying a sound event in the scene with reference to the scene state model and a predetermined scene grammar stored in a memory, and generating with the processor an output corresponding to the sound event.
