Abstract
Disclosed are a voice communication system and a voice communication method which set a subtraction weight for each of a plurality of frequency subbands split based on a particular frequency response characteristic set to the system, calculate a gain function for each frequency subband according to the particular frequency response characteristic based on the subtraction weight for each of the frequency subbands, and improve sound quality of a voice signal by reflecting the calculated gain function.
