Matlab函数 采集一段浊音和清音语音信号
(1) 使用录音软件或者Matlab函数,分别采集一段浊音和清音语音信号(是你自己说的,如:a,o,s等),采样率为8KHz,量化精度为16比特线性码,存在自己指定的目录下,例如D盘根目录下叫sound的文件夹中,录音文件名为yourfilename_a.wav,yourfilename_s.wav等。录音的软件和Matlab函数的使用见随后的附录。
(2) 根据语音信号的短时平稳特性,分析帧长取30ms(或10ms~50ms);
(3) 利用上述基音提取的三种方法(任选两种方法)的编程流程图(图1、图2和图3)编制浊音语音基音提取的matlab程序,上机调试给出相应波形,并根据图形,分析计算出基音周期。所用公式为:
(1.5)
其中 是基音脉冲处所对应的位置, 是抽样频率, 是基音周期。
(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。
