ECHO SUPPRESSING METHOD AND DEVICE

摘要

A converting section (100) uses either the output signal of a sound collector or the signal which is the remainder of the subtraction of the output of an echo chancellor from the output signal of the collector as a first signal, corrects the first signal by using a crosstalk estimated value indicating the estimated value of the amount of crosstalk of the echo into the first signal, and thus limits the corrected first signal below the estimated near-end noise.
