| 摘 要： | 基于语音周期性的特点,提出了一种预加重的MMSE语音增强的改进算法.首先,算法在尽量保留语音信息基础上对带噪语音预加重,使信噪比提高.预加重过程将根据带噪语音信号的周期性的强弱对信号动态加权.处理结果再作为MMSE语音增强的输入并将有利于提高最终的去噪效果.

| Abstract: | A modified MMSE algorithm for speech enhancement based on speech periodic property is presented. A Pre-emphasis filter is used, it aims keeping speech information best rather than eliminating the noise completely. The noisy speech is weighted dynamically according to its periodic property. The processing result can be used as input in MMSE enhancement algorithms to get a better noise reduction. |
