Comparison of Noise Suppression Methods in Voice CODEC
음성부호화기에서의 잡음제거 방식 비교
Abstract
Considerable research in the last three decades has examined the problem of enhancement of speech degraded by additive background noise. We compare traditional methods such as spectral subtraction and Wiener filter, recently proposed psychoacoustic model based methods such as perceptual filter and noise suppression in EVRC in terms of performance and complexity.
