matlab声纹识别代码

用matlab实现说话人识别的一个案例。

function dist = dtw（ tr ）
n=size（t1）;
m=size（r1）;
%%帧匹配距离距阵
d=zeros（nm）;
 
for i=1:n
    for j=1:m
        d（ij）=sum（（t（i:）-r（j:））.^2）;
    end
end
 
%%累积距离矩阵
D=ones（nm）*realmax;
D（11）=d（11）;
%%动态规划
for i=2:n
    for j=1:m
        D1=D（i-1j）;
        if j>1
            D2=D（i-1j-1）;
        else
            D2=realmax;
        end
       
        if j>2
            D3=D（i-1j-2）;
        else
            D3=realmax;
        end
        D（ij）=d（ij）+min（[D1D2D3]）;
    end
end
dist=D（nm）;
end
