I will share the issues I had with setting up Dragon NaturallySpeaking within my Windows XP guest, on an Ubuntu Linux host.
Upgrading to Virtualbox 3.1.4
- earlier versions of virtualbox had a nasty bug in which audio input was choppy, however, issue was resolved in the latest version.
" your processor speed is not adequate"
- If you get this error when trying to install Dragon, you should ensure that your CPU frequency scaling is set to performance, rather than ondemand. To do this, right-click on your panel, add to panel, and choose CPU frequency scaling Monitor, then just select performance. This should ensure that your processor is running full speed.

Thats it, good luck!
