You can use an external program to extract the audio from the avi file into a wav file and use the solutions you already have. Depending on you OS you can probably find a program with a CLI and fully automate the process from MATLAB.

I don't think there is a built in MATLAB function for doing it. I am betting you could write your own function to do it, but I don't see why you would want to.
