i changed the read method after constructing a 
pipedinputstream/opipedoutputstream to

int n=auin.read(frame, 0, frame.length);
                        System.out.println(""+n+" bytes read.");
                        int m=pcm2speex.read();       
                        System.out.println("something recieved");

and still can't recieve a single value from the pipe ..
