Smart sensor system and method for threat detection and response based on detection of a vocal phrase

A threat detection and response method, comprising, by one or more processors:

• receiving sound data from at least one sound sensor configured to sense sound within a detection zone;
• analyzing the sound data to detect a vocal phrase within the sensed sound;
• determining that the detected vocal phrase corresponds to a pre-defined vocal phrase associated with a threat;
• and
• communicating an existence of the threat to a recipient device.

A threat detection and response system, comprising a processor configured to:

• receive sound data generated by at least one sound sensor configured to sense sound within a detection zone;
• analyze the sound data to detect a vocal phrase within the sensed sound;
• determine that the detected vocal phrase corresponds to a pre-defined vocal phrase associated with a threat;
• and
• communicate an existence of the threat to a recipient device.

A threat detection sensor, comprising:

• at least one sound sensor configured to sense sound within a detection zone;
• and
• a processor unit coupled to the at least one sound sensor and configured to:
• receive the sound data;
• analyze the sound data to detect initial evidence of the vocal phrase within the sensed sound;
• and
• after detecting the initial evidence of the vocal phrase, transmit the sound data corresponding to the sensed sound, wherein the transmitted sound data is used to confirm an existence of a threat by confirming that that the vocal phrase is within the sensed sound.
