Hey, this is great. I just managed to configure Festival (speach synthesizer) to read the contents of the clipboard. If any body is interested, the shell script is
dcop klipper klipper getClipboardContents > $HOME/festivaltext
festival --tts $HOME/festivaltext
I have Mandrake 10.0 and have festival, and festvox rpms installed.
I created an icon in the taskbar to call this shellscript. So now when I want to read text, all I need to do is select the text in any application, right click and copy to clipboard and then click the shortcut to the above shellscript and Festival will read it aloud. There maybe better and more efficient ways to do it but this is the best I could find.
