i have a java text-to-speech project and I want to concatenate the multiple audio files('ogg' format) so that i play them in one stream, anyone has any idea about it? can java do this? if you can lead me to any resource or tutorial or anything helpful I will be very pleased, thanks a lot.

For concatenation I would use some external command-line tool via Runtime.exec() or ProcessBuilder.
Probably, oggcat should work in your case: http://en.flossmanuals.net/ogg-theora/command-line-editing/cat-files/ (it's about video, but ogg container is the same, make sense to try, anyway)
As for playing, there is JOrbis library and probably something else.

thanks I will look at it :) , i have no problem in playing individual files one after another but I want to improve my TTS by merging the diphones so it will become one process (one play). – Nawras Oct 04 '12 at 11:11
