This is a method regularly used in conferences and events, where a text version of dialogue is displayed on a large screen in ‘real time’. Deaf people can request this service for smaller meetings using a laptop screen instead of a large screen.
A trained professional will use a shorthand code keyboard to note verbatim what the speaker is saying. This code is processed into English and displayed on a screen which can be read by the audience to help them follow the presentation or speaker. A typist can record at speeds of up to 200 words per minute, and give additional information like audience applauds and laughter. Watching the screen is very similar to having subtitles at your event or meeting.
