Hello everybody, recently i m working on speech analysis. I cut many audio files into vowel segment in second. But the issue is that i cannot work properly with the segmented vowels audios such as extracted their pitch, mfcc and other features. I attached to my problem the code of extracting pitch from those segmented vowels audios. Below is the code and the error when i tried to extract pitch features from those segmented vowels audios. I need to know where the error come from and how to fix it. Thank you for your answers and help

file = dir ('E:\I\*.wav');

M= length (file)

for k = 1:36

%pitch extraction

[speech,Fs]= audioread(fullfile('E:\I\',file(k).name));

a=(speech);

ptch = pwelch(speech,Fs);

signalpitch(k,:) = ptch;

extractpitch = signalpitch (:,:);

end

Below is the error
