I've formatted the code in your questions. Please format your code in the future so people can read it properly.

[Prashant Saini]

Can you just tell me how to use audiorecoder function in this i used that too but error coming up

how should i convert this ?

clc ;

close all ;

clear all;

Fs=8000 ;

Nseconds = 1 ;

samp=6 ;

words=5 ;

for i= 1:1:samp

fprintf('say AHEAD immediately after hitting enter ');

input ('');

x= wavrecord(Nseconds*Fs,Fs,'double ');

[s(i,:),g] = lpc(x,12); % 12+1 features

%plot(s(i ,:));

end

If you edit your comment and format your code, I can read it more easily and will be happy to help.

Select the code in your comment and use the text/code toggle

Also, you'll probably find all of the answers to your questions in the documentation,

https://www.mathworks.com/help/matlab/ref/audiorecorder.html

You can compare those inputs with the inputs from wavrecord:

If there's something specific I can help with, let me know.

Answer 1

[Adam Danz]

The error message tells you the problem.

error: Unrecognized function or variable 'wavrecord'.

Matlab doesn't know what wavrecord is. If this is a function, make sure it's added to the matlab path.

UPDATE

According to this answer, this function has been removed from Matlab several years ago.
