moving a signal from matlab to simulink

recObj = audiorecorder
disp('Start.')
recordblocking(recObj, 5);
disp('End.');
play(recObj);
y = getaudiodata(recObj);

the code above records your voice for 5 seconds then gets it and puts it in y the problem is that i cant seen to move y into the simulink working space, I've tried from workspace and get signal but nothing worked,,, help appreciated :)
