[users] Impress: PowerPoint narration - save me from microsoft

[bill]

As a sideline I teach at the college level.  I have agreed to do an 
on-line course this term and in order to prepare the on-line lectures I 
need to feed a narrated powerpoint lecture into a processor that 
converts it to interactive HTML.

I have use Impress for all my presentations to date, but can't find a 
way to make a narrated presentation.
Am I missing something, or do I have to use micro$soft's powerpoint ?
