Hi sir, thanks for your reply...

i came to know how to process single raw wav file, But i am using julius with Qt and not trhough commandline. so i cant make use of those commands, and i can't use raw wav files for processing...i am using live mircrophone(mic) for telling commands. that is where i am getting problem. i am getting problem in the following api of julius i.e 

ret = j_recognize_stream(recog);

Thanks.

I can't say anything about Qt, but if the file format is an issue then you can use a sound utility like sox to easily convert from one format to another.
