Abstract
A monitoring system includes at least one detector having a housing that carries at least one ambient condition sensor. Control circuits carried by the housing are coupled to the at least one ambient condition sensor. A separate audio input transducer carried by the housing is coupled to the control circuits, wherein the control circuits include signal processing circuits coupled to the separate audio input transducer. The signal processing circuits cancel predetermined audio received from the separate audio input transducer and output a processed speech signal that is coupled to speech recognition circuitry. The speech recognition circuitry recognizes selected speech to implement predetermined functions.
