Abstract
Audio alerts are provided in an environment, such as a house, concerning categorized events to be reported. Examples of the events are receipt of e-mails and voice mails. The presence of a person entering or leaving a space of the environment is detected and a processing system determines reportable event categories that have occurred. Each possible event category has a corresponding audio signature. The event categories signatures that have occurred are played either simultaneously or sequentially, within the hearing of the person detected.
