The use of ~ notation is only available in R2009b or later. You can replace ~ with a unwanted variable name such as temp, trash, dummy,...

MATLAB: Audio file (.wav) being overwritten

You have

speech = ('coch4.wav');
speech2 = speech;

So your speech2 filename is the same as your speech filename.

[y,Fs]=audioread(speech2); %don't use wavread or audioread

So you read from coch4.wav via speech2 filename

audiowrite(speech, speech_trimmed, 44100);

and then you write to the file name given by speech, which is the same as the filename given by speech2, so you are writing to the same file that you read the data from.

audiowrite cannot save the file in .mat format. Use extension of an audio file. Also use concotenation brackets [ ]

audiowrite([Audio_files(p).name '.wav'], extractedData,fs );
