It might be an idea to change the interaction structure too.  I can forsee 
different user groups being prepared to put up with different costs 
depending on what they get out of voice recognition.  For example, different 
user groups will be willing to spend different amounts of time learning how 
to use the system.  It would probably be useful to run the UI design process 
using a user centered design methodology.

WXP:
There's probably a few techniques that would produce a good design.  One 
would be taking an engineering approach involving cognitive modelling. 
Obviously, you probably would want to run a set of thinking aloud sessions 
to validate any design - although running a thinking aloud session for a 
voice recognition system might be a bit interesting :).

Ouch... That must hurt.  The process of sub-vocal rehersal that is used 
during short term / working memory and speech production both use Wernicke's 
Area and Broca's Area in the brain.  This conflict over the use of 
neurological functions is probably dragging down your performance in both 
memory and speech production.  So, it's probably a high priority thing to 
try and sort out in any future system.  Not only that, it seems an 
interesting challenge and you're a friend.

Awww.  Say hi to the X-Dog from me.
