| 摘 要： | 针对受受不同程度干扰噪声污染的功率值语音滤波问题,提出一种依据噪声污染情况自适应选取不同策略滤波的算法.该算法在滤波时无需设定参数,自适应能力强,在滤除噪声并保护语音细节方面比其他算法有较大提高,并且在严重噪声污染的情况下,其对语音的恢复也有较好效果.

| Abstract: | To effectively remove interference noise produced in the process of collection and transmission of digital sound,this paper presents a self-adaptive algorithm,which can select different filtering strategy according to the noise situation.Without need to set parameters when filtering,this algorithm is much better than other algorithms in the noise filtering effect and the preserving of sound detail,especially the restoring of heavily polluted sound. |
