Abstract: A voice communication system of the so-called "hands-off" type in which a telephone or other speaker-microphone combination in relatively noise free environment, usually an interior environment, can be in voice communication with a so-called "hands-off" speaker-microphone combination located in a relatively noisy environment, usually an exterior environment and where substantial and variable background noise may exist. A microprocessor is used to effectively monitor a telephone link between the two microphone-speaker combinations and will provide microphone control to that microphone located in the relatively noise free environment. Thus, if voice signals are detected on the telephone link, and if those voice signals eminate from the relatively noise free or relatively quiet environment, voice communication control will remain with the party in that environment.
