METHOD AND APPARATUS FOR REMOVING NOISE

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for removing noise capable of obtaining an emphasized voice with reduced distortion and noise regardless of types of noise and values of an SNR. SOLUTION: The apparatus has a weighted degraded-voice calculating section 14 for calculating a weighted degraded-voice power spectrum from a degraded voice power spectrum and an estimated noise power spectrum. Also, the apparatus has a suppression coefficient correcting section for calculating a corrected suppression coefficient in response to the value of the SNR and a suppression coefficient.
