(1) 分别采集一段浊音和清音语音信号(是你自己说的),采样率为8KHZ,量化精度为16比特线性码;
(2) 分析帧长取为30ms(或10ms~50ms);
(3) 根据语音信号倒谱分析和LPC谱分析的编程流程图(图2.1、图2.2)编制浊音语音信号谱分析的matlab程序,上机调试给出相应波形,并根据图形,观察共振峰情况;
(4) 将语音信号换为清音语音,运行程序,与浊音语音的运行结果进行比较,并得出结论。
(5) 在LPC谱分析中,改变阶数p (p分别等于4、8、12、40)时,观察对谱包络的影响,并与信号谱(DFT谱)进行比较。

超混沌chen-lee系统引入一个非线性状态反馈控制,将混沌Chen-Lee系统构造成四维超混沌系统。将这个四维超混沌系统作为驱动系统。采用主动控制方法构造一个响应系统,进一步选择适当的控制器使驱动-响应系统达到有限时间同步。(Hyperchaotic chen-lee system into a nonlinear state feedback control, the chaos Chen-Lee system constructed four-dimensional hyperchaotic system. This four-dimensional hyperchaotic system as the drive system. Using active control methods to create a response system, to further select the appropriate controller to drive- response system to the finite time synchronization.)
