Thanks Art but i think i'm going to walk away from this one.
Just too hard with voice "assistance" vs voice "guidance" systems in play.
It appears Canon / Ricoh are more advanced and I don't have the resources and time to check differences and build a technical case to remain involved in tender.
Well given we get very few requests for this kind of product it is not likely to affect us in any great details.
thanks for assisting.
