Abstract

The present invention teaches a system for improving the clarity of a voice spoken within an enclosed space. The system comprises a first microphone, positioned at a first location, for receiving the audible communication and for converting the audible communication at the first location into a first audio signal. The system also comprises a loudspeaker for receiving the first audio signal, and for converting the first audio signal into a first reproduced audible communication, the reproduced audible communication also being fed back and received by the first microphone and converted with the audible communication into the first audio signal. Moreover, the system comprises an acoustic echo cancellation system for determining the relationship between the received audible communication by the first microphone and the first audio signal comprising both the audible communication and the reproduced audible communication fed back to the first microphone, and for removing the first reproduced audible communication fed back to the first microphone from the first audio signal received by the loudspeaker.
