ABSTRACT:
A method for determining whether a user having a communications device has encountered a perilous situation includes detecting a sound with the communications device and determining whether the sound is indicative of the perilous situation. The method generates a query with the communications device for the user when the sound is determined to be indicative of the perilous situation and waits for a response from the user via the communications device. The response or lack thereof is capable of confirming the perilous situation or a false alarm.
