Hi,
I am uploading an audio signal of 3 seconds in matlab, but after uploading it is showing 0.5 seconds audio and the signal is totally change. How can I change the time, so that I can listen full audio of 3 seconds and implement other operation on my 3 seconds audio. Please guide me.
Thanks in advance.

How are you "uploading" the audio signal?

Please post your code for "uploading" your voice.

load('norway.mat')
[y,fs] = audioread('norway.wav');
audioinfo('norway.wav')
plot(y);
play(norway);
title('Norway is a very beautiful country');
xlabel('Time(s)')
ylabel('Frequency(Hz)');
grid on;

play() is not a function by itself: it is primarily an audioplayer method, but you do not have any audioplayer objects -- not unless there is one in what you load()
If audiofino on the .wav file is showing 48000 then somehow you managed to create the file as if it were 48000 Hz.
Try
sound(y, 8000)

Please attach norway.wav
You might need to zip it and attach the .zip

Hi Wave file is not uploading here.
Can you please tell me which one is the correct command for taking sum of 10 imfs and residual? I am comfused in this.
s= plus(sum(imf(5:10)),residual);
or
s= plus(sum(imf(5,10)),residual);
or
s= plus(sum(imf(5,10,:)),residual);

Zip the audio file. Upload the zip file.
I do not know what an imfs is in this context?
Some of what you wrote suggests that you might have 6 elements, not 10. Elements 5, 6, 7, 8, 9, 10 is a total of 6 elements.

You need to tell audiowriter that the sample rate, FS, is 8000.
