Just in case you got a wave file

[y, Fs, nbits] = wavread(filename) %load the wav
[m d] = wavfinfo(filename) %get the wav information

Another way to get the length in seconds is:

siz = wavread(filename,'size') %siz = [samples channels]
siz(1)/Fs %should give you the length in seconds

MATLAB: How to slice an audio from the front, and extract and save audio from the back.

You can just delete the initial part of the audio signal and save it into the audio file. For example

[s, fs] = audioread('sample.wav');
s2 = s;
s2(1:2*fs) = [];
audiowrite('new_file.wav', s2, fs);

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.
