在Linux Matlab中利用声卡采集声音，需要用到audiorecorder函数（在windows中是wavrecord），
r = audiorecorder(44100, 16, 1); %采样率，采样位数，，单声道record(r); % speak into microphone…调用record方法的时候开始录音pause(r);p = play(r); % listenresume(r); % speak againstop(r);p = play(r); % listen to complete recordingmySpeech = getaudiodata(r, ‘int16’); % get data as int16 array
所有欺骗中，自欺是最为严重的
