I have the following MATLAB code which does plotting while recording a voice at the same time. I want to add lines so that it automatically recognizes a pattern from the plott

close all

clear all

clc

%Define parameters

fs = 96000; % Sampling frequency

nBits = 24; % Number of bits

nChannels = 1; % Number of channels

duration = inf; % Duration of recording in seconds

%Create recorder object

recObj = audiorecorder(fs, nBits, nChannels);

disp('Start Recording:')

recObj.record(duration);

while recObj.isrecording()

pause(0.1);

plot(recObj.getaudiodata());

title('The recording of ')

xlabel('Time')

ylabel('Audio Signal')

drawnow();

%Check for key press

if isequal(get(gcf,'CurrentKey'),'escape')

%Stop recording if 'Escape' is pressed

break;

end

end

disp('End of Recording');
