            Most of G.729 source code is written in C.But this one is written in matlab.<br>
follow these steps to use it:<br>
1.To coder a speech(ensure it as a row vector variable in matlab),simply type<br>
"G729code(speech)",then you will see a file called 'coding.bit' in your directory.<br>
<br>
2.To decoder the codestream.bit,first,copy the file 'codestream.bit' to
your G.729decoder directory,you simply type "main",and it will decoder
the above file 'coding.bit'to a speech in your matlab(syn_speech). <br>
