Abstract

See full text

A speech communication system includes a speech service compartment for holding one or more system users. The speech service compartment includes a plurality of acoustic zones having varying acoustic environments. At least one input microphone is located within the speech service compartment, for developing microphone input signals from the one or more system users. At least one loudspeaker is located within the service compartment. An in-car communication (ICC) system receives and processes the microphone input signals, forming loudspeaker output signals that are provided to one or more of the at least one output loudspeakers. The ICC system includes at least one of a speaker dedicated signal processing module and a listener specific signal processing module, that controls the processing of the microphone input signal and/or forming of the loudspeaker output signal based, at least in part, on at least one of an associated acoustic environment(s) and resulting psychoacoustic effect(s).
