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. If the party in the relatively noise free or quiet environment ceases talking, then the party in the relatively noisy environment may exercise speaking control over the telephone link, but only so long as the party in the relatively noise free environment does not generate any sound over the voice communication link. The processor will constantly monitor to determine whether or not the party in the relatively noise free environment is attempting to exercise control over the link by speaking and will effectively provide that control to the party in that relatively noise free environment.
