Description: 在MATLAB环境下实现基于矢量量化的说话人识别系统。在实时录音的情况下，利用该说话人识别系统，对不同的人的1s～7s的语音进行辨识。实现与文本无关的自动说话人确认的实时识别。
使用说明：
1 训练
打开Matlab 使Current Directory为VQ所在的文件夹(比如：E:\vq)
在Command windows中输入
train( 1s\ ,7)
这是将1s中的wav文件进行特征提取并产生VQ码本，
在workspace中有个ans的文件保存为.m文件，比如7.m，保存在1s文件夹下。（1s表示语音长1秒）
2 识别
在Command windows中输入
test( 4s/ ,7,ans)
其中的ans 就是步骤1产生的码本。（必须保证7.m在workspace中打开）此时就会显示结果。
Speaker 1 matches with speaker 2
Speaker 2 matches with speaker 3
Speaker 3 matches with speaker 4
Speaker 4 matches with speaker 6
Speaker 5 matches with speaker 2
Speaker 6 matches with speaker 7
Speaker 7 matches with speaker 7
1s、4s分别是7个不同的人说话的录音，只是打乱了次序。-err

Description: 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，即可合成信号的时域图形，听一下声音。
（4）对原音频信号进行1024点的分段付立业分析meshgrid
（5）根据主要频线合成音频，并画出时域图形，试听合成效果。
（6）采用线性插值（linspace）和傅立业反变换(fliplr, ifft)分别合成音频，并画出时域图形，试听效果。
