How to differentiate between music and speech audio files?

I have a college project to detect whether an audible file is music or speech using matlab. So i used this output = test(filename,band,start_sec);

but kept on saying: Undefined function or method 'test'

How can i solve this problem and Is there any other code or function i can use to differentiate between them?

Can you provide me link or code file for your project? I have same kind of project. Thanks

If "test" is an mfile function that somebody gave you, make sure it is in a directory where MATLAB can see it, i.e., put it in your working directory or put its current directoy on the MATLAB search path (doc pathtool)

I found this function in someone's research and it didn't provide it's mfile function

Well, if you don't have the code, hopefully you now understand why you're getting

Undefined function or method 'test'

Time to start browsing the FEX, I guess. How about this
