| 摘 要： | 依据数字语音信号的特点，提出了一种用于语音处理的形态学滤波算法．实验结果表明，该方法有效地抑制了噪声的干扰，对混噪语音质量的增强效果显著．由于形态滤波器的性能与结构元素有关，因此考查了结构元素是寸的变化对增强语音信噪比的改善情况．研究表明，结构元素的宽度变化对增强后语音的输出信噪比的影响较大．

| Abstract: | Based on the traits of digital speech signals,a new morphological filtering algorithm is proposed for speech enhancement.Experiments show that the new filter is quite effective in suppressing noise and improving the quality of noisy speech.The paper reveals that the performance of morphological filters is based on reasonably chosen structuring elements,and presents the influence of the structuring element's size on the proposed enhancement method.The results show that the width of the structuring element is more important than the height in the performance. |
