In the film Star Trek IV - The Voyage Home, one of my favourite moments is when James Doohan, paying the part of chief engineer Scotty tries talking to a 1986 vintage desktop PC and his colleague Dr "Bones" McCoy says, "Scotty, I think you have to use the keyboard." Scotty replies, "A keyboard? Oh! How quaint!"
The truth of the matter is that at the time the Star Trek film was made, speech recognition technology was still in its infancy, and was on the whole, confined to highly specialised markets. For example, in most medical dramas at some stage there will be film of the pathology examination with the doctor dictating notes into a microphone hanging over a body. In practice, this was one of the specialist markets for voice recognition technology.
A brief history
In 1985, Apricot Computers produced a portable PC fitted with a hinged microphone at the side of the display. Users of the computer were able to perform simple dictated tasks in DOS (the early operating system).
