基于噪声估计和听觉掩蔽效应的语音增强
Speech enhancement based on noise estimation and auditory masking properties.
摘要
Abstract
Aiming at non-stationary noise environment and low SNR, a non-stationary noise estimation method is proposed by using low-frequency regions of noisy specch,a weighting factor is used to track the time variation of noise.Then,the estimated noise can be used to self-adaptively adjust enhancement parameters according to auditory masking properties.The experiment result shows that the method is effective to reduce background noise,improve SNR and decrease speech distortion.关键词
