rec_base_file.m

在ｍａｔｌａｂ上实现的特定人小词汇量的语音识别程序。先输入１０个模板

function rec_base_file()
disp('产生参考模板...')
for i=1:10
	fname = sprintf('rossi_%d.wav',i);
	x = wavread(fname);
    [x1 x2] = vad(x);
	m = mfcc(x);
	m = m(x1-2:x2-2,:);
	ref(i).mfcc = m;
end

exit = 1;
while exit==1,
disp('系统以准备就绪，等待指令:')
[x1 x2 x] = rossi_record_vad();
	m = mfcc(x);
	m = m(x1-2:x2-2,:);
    test.mfcc=m;
    
for i=1:10
    distance(i) = dtw(test.mfcc,ref(i).mfcc);
end

    [d,result]=min(distance);
    if result<10
    fprintf('指令是： %d\n', result);
    for i=1:10
    fprintf('the # %d distance is %d\n',i,abs(distance(i)));
    end
    else
        exit = 0;
        fprintf('正在退出..........\n')
    end
end
fprintf('祝贺你!! 退出成功');
