摘要

A technique of a wireless microphone having an error correcting function is enabled to lighten the degradation of a voice quality at a communication time by correcting an error preponderantly on an important portion of voice data to be transmitted. A voice data division unit (143) of a processing unit (14) divides digital voice data into the important portion and another according to a predetermined regularity, and an error correction first encoder (15) adds an error correcting redundant bit at a higher ratio than that of said another to the important portion.
