摘要
语音信号处理技术的基本概念和发展过程;用基于短时分形维数的模糊控制滤波方法,对语音信号中的噪声进行了滤波处理;提出了网络分形维数和短时分形维数的新算法,并讨论了模糊控制滤波方法中的模糊控制参数的选取问题;给出了在虚拟仪器(VI)LabVIEW7.0软件平台上对语音信号进行仿真的结果。
The developing process and basic concept of speech signal processing are introduced. According to the method of short time divided form numbers fuzzy control filter, the noise in the speech signal is filtered. The new algorithm of network divided form numbers and short time divided form numbers is pointed out. The choice algorithm of fuzzy control parameter in the filter method of fuzzy control is discussed. Speech signal is simulated on the workbench of virtual instrument（VI） LabVIEW 7. 0 software.
