摘要
提出了一种适于低信噪比下的语音增强算法。该算法以传统的谱减法为基础,所用减参数是根据人耳听觉掩蔽效应提出的且是自适应的。对该算法进行了客观和主观测试,结果表明:相对于传统的谱减法,该算法能更好地抑制残留噪声和背景噪声,特别是对低信噪比的语音信号。
A speech enhancement method for low S/N ratio is proposed.This algorithm is based on traditional spectral subtraction.Subtract parameter is got based on the masking properties of human auditory and self-adaptive.Subjective and objective tests are made on this algorithm.The results show this algorithm is very effective to reduce the residual noise and the background noise,especially for low S/N ratio speech compared to the traditional spectral subtraction.
