Problem with StopRecording button

I'm using this code to record my voice, but when the recording is less than 5 seconds, the file played by the function sound is the file recorded before the last one.

This function records the voice when i push the 'StartRecording' button:

function StartRecording_Callback(hObject, eventdata, handles)

 RecordStatus = get(hObject,'Value');
 runstr=get(hObject,'string');
 if RecordStatus == 1
    % start recording
    fs = 44100;
    obj = audiorecorder(fs, 16, 1);
    recordblocking(obj, 5);
    y = getaudiodata(obj);
    clear obj
    save recording.mat y
 else
    % stop recording
    StopRecording(handles);
 end

This function is the callback for the function StopRecording:

function StopButton_Callback(hObject, eventdata, handles)
StopRecording(guidata(hObject));

This function saves, plays and plots the audio file:

function StopRecording(handles)
  fs = 44100;
  load recording y;
  [filename, pathname] = uiputfile('*.wav', 'Save file name');
  cd (pathname);
  audiowrite(filename, y, fs);
  sound(y,fs);
  handles.x = y;
  handles.fs = fs;
  axes(handles.axes1);
  time = 0:1/fs:(length(handles.x)-1)/fs;
  plot(time,handles.x);
  title('Original Signal');
  axes(handles.axes2);
  specgram(handles.x, 1024, handles.fs);
  title('Encrypted Signal');

I want to record, play and plot the file just created.

U can use this code :

val= get(hObject,'Value');
runstr=get(hObject,'string');
fs=44100;
record=audiorecorder(fs,16,1);
recordblocking(record,10);
y=getaudiodata(record);
[filename, pathname] = uiputfile('*.wav', 'Save file name');
cd(pathname);
audiowrite(filename,y,fs);
sound(y,fs);
handles.x=y;
handles.fs=fs;
axes(handles.axes1);
time=0:1/fs:(length(handles.x)-1)/fs;
plot(time,handles.x);
title('Orijinal sinyal');
axes(handles.axes2);
windows_length=ceil(20*fs/1000);
specgram(handles.x,windows_length,windows_length/2);
title('Orjinal sinyalin spektogrami');

xlims=num2str(get(handles.axes1,'Xlim'));
ylims=num2str(get(handles.axes1,'Ylim'));
handles.zoom_history=[];
end
guidata(hObject,handles);
