1. A method for operating a sound recognition sensor, the method comprising: receiving an analog signal that may contain a signature sound; extracting sound parameter information from the analog signal; comparing the sound parameter information to a sound parameter reference stored locally with the sound recognition sensor to detect when the signature sound is received in the analog signal; generating a trigger signal when a signature sound is detected; sending a portion of the extracted sound parameter information to a remote training location for adaptive training when the signature sound is falsely detected; and receiving an updated sound parameter reference from the remote training location when the signature sound is falsely detected.
