Are you using at least Speakup 1.0? That's the latest stable version. If so, are you, perhaps, loading a keymap from an older version over the one that has cut and paste in it? This will happen if you previously used something like 0.10 and upgraded. In that case, find the script that loads your keymap and determine where the keymap is. Replace the keymap with the one in /usr/src/linux/drivers/char/speakup/speakupmap.map. Hope this helps. By the way, this is a problem on Debian stable as well as it was modified with an older Speakup. Good luck.
