hello , I was trying to apply GUI with guide to my code voice recognition I actually dont know a lot about GUI .first, what I want to do is to assgin a push button for recording , how can I do that? I know how to make the figure but I dont know how to proceed after that starting from the option view callbacks ,here is a simple code as a start ,
rec1 = audiorecorder(22050, 16, 2);
disp('Start speaking.')
recordblocking(rec1, 2);
disp('End of Recording.');
any advice would be appreciated .

Try reading the getting started section of GUI's , and have a look in to these lines:
% Create the Audio recorder Object
>> rec = audiorecorder(22050, 16, 2);
% Create a Function to create the GUI
function test(rec)
f= figure ;
uicontrol(f,'style','pushbutton','position',[10 10 200 20],'String','Record','CallBack',@buttonCallback) ;
function buttonCallback(~,~)
disp('Recording... start talking');
rec.recordblocking(2);
disp('Stopped.');
end
end
% Execute the function with the object as a parameter
>> test(rec)

thanks that helped , do you know how to combine it with rest of my code ? I want the code be waiting for the pushbutton then continue excuting ,
[x1,fs]=wavread('C:\Users\user\Documents\MATLAB\red.wav');
X1=x1(:,1);
rec = audiorecorder(22050, 16, 2);
test(rec);
play(rec);
y= getaudiodata(rec);
Y=y(:,1);
z1=xcorr(X1,Y);
maxred=max(z1);
length1=length(z1);
t1=-((length1-1)/2):1:((length1-1)/2);
t1=t1';
max5=15; all=[maxred max5]
m=max(all);
if m<=maxred
soundsc(wavread('red.wav'),22050)
disp('red');
else soundsc(wavread('denied.wav'),8000)
disp('denied');
end
