利用函数wavread对语音信号进行采样
- 语音信号的录音、读入、放音等:利用函数wavread对语音信号进行采样,记住采样频率和采样点数,给出以下语音的波形图(2.wav),wavread的用法参见mablab帮助文件。利用wavplay或soundview放音。也可以利用wavrecord自己录制一段语音,并进行以上操作(需要话筒)。-Speech signal recording, reading, playback, etc.: the voice signal using the function wavread samplin

vioce-signal-processing
- 录制自己的一段语音,时间控制在15秒到30秒左右;利用wavread函数对自己的语音进行采样,记住采样频率。 (1)画出原始语音信号的时域波形,而后以1秒为间隔,求出每秒数据的功率谱。 (2)根据语音信号特点,分别设计FIR及IIR滤波器,分别画出滤波器幅频和相频特性曲线。用设计的滤波器对信号滤波,画出滤波后时域波形。用sound函数回放语音信号。 (3)求出特征频段语音信号随时间变化的曲线(每间隔0.05秒求一次功率谱)。 -Record your own voice for

ding
- 选取windows系统自带的ding.wav信号作为分析对象,在Matlab软件平台下,利用函数wavread对音频信号进行采样,记住采样频率和采样点数,听一下原始声音sound(y, fs, bits)。 (2)音频信号的频谱分析,先画出音频信号的时域波形;然后对音频号进行快速傅里叶变换fft(y,N),N取32768,画出信号的频谱特性,加深对频谱特性的理解。 (3)根据频谱,反演时域特性,画出时域波形。寻找幅值最大的两个频率,此频率除以fft点数在乘以采样频率就是信号的主频,即可合
