Hi Mark - I thought you'd vanished into a back hole! Just a quick reply on one point. I have on user who has no voicing - he speaks in a what I can only describe as a hoarse shout. He was determined to use voice and was working with the pilot navigating through the menus using "next" and "OK". His breath control wasn't adequate for him to say eg. "channel 5" within the allowable time window. I need to follow up to see how he is doing. Is no-one else in the UK using voice recognition for EC?
