I am getting parse error at the marked bracket, I don't know why!

Please post (or attach as a m file) the exact code you're using. Without any modification. Also post the full text of the error message.
You've given us conflicting versions of your code. With this particular error, the problem is from what comes before the [.

[sp1,fs1] = audioread('F:\Moodle\Summer18\sync porject\iitb recordings\01_SPK1_05_06_2017-09.wav');
There should be no stars, in the first place. And this line should be copied above your function audio not, after the function.

[sp1,fs1] = audioread('F:\Moodle\Summer18\sync porject\iitb recordings\01_SPK1_05_06_2017-09.wav');
[ar1,fs4] = audioread('F:\Moodle\Summer18\sync porject\iitb recordings\04_ARRAY1_05_06_2017-09.wav');
ar11 = ar1.*(100);
function [fdly,tdly] = delaycalc(sig1,sig2)
i = 1;
j = 1;
fdly = zeros(1,266);
tdly = zeros(1,266);
while (i <= 12768000)
a = sig1(i:48000);
b = sig2(i:48000);
[cor,lag] = xcorr(a,b,'coeff');
[~,Il] = max(abs(cor));
lagdly = lag(Il);
tmdly = lagdly/48000;
i = i+48000;
j = j+1;
display(tmdly)
display(lagdly)
end
Now it shows this error: Line 5: FUNCTION keyword use is invalid here. This might cause later message about END. Line 5: Parse error at ']': usage might be invalid MATLAB syntax
Line 5: Parse error at ')': usage might be invalid MATLAB syntax

Save this code first, defualt this will be saved on the name delaycalc. Save this in some folder.
function [fdly,tdly] = delaycalc(sig1,sig2)
i = 1;
j = 1;
fdly = zeros(1,266);
tdly = zeros(1,266);
while (i <= 12768000)
a = sig1(i:48000);
b = sig2(i:48000);
[cor,lag] = xcorr(a,b,'coeff');
[~,Il] = max(abs(cor));
lagdly = lag(Il);
tmdly = lagdly/48000;
i = i+48000;
j = j+1;
display(tmdly)
display(lagdly)
end
And then, change the path, and go to that folder. Now, you can call that function.
[sp1,fs1] = audioread('F:\Moodle\Summer18\sync porject\iitb recordings\01_SPK1_05_06_2017-09.wav');
[fdly,tdly] = delaycalc(sp1,fs1)
