How can I read .amr speech file in MATLAB? Do I need any binary file for this, as MATLAB only supports .wav and .au files?

I want to read .amr audio file in matlab just as there is a function for reading .wav file (wavread). Is there any possible way that how can I achieve this task.

It appears you would have to write the code yourself. I do not find any MATLAB converter on the 'net.

You might be able to find a convertor written in JAVA and then call that from MATLAB.

It would probably be easier to use an external program to convert the files.

Thanks Roberso. I think Calling from java to matlab will require some java expertise also, which i dont have in my case. But yes, for me writing code for amr speech decoding seems to be a good alternative. For this, i came to know that ARM speech is based on ACELP algorithm. But in implementing ACELP in matlab i am unable to find any useful paper/book or material in net. Can you please help me in this.

Sorry I am not familiar with ACELP
