A regular computer keyboard, monitor and word processor can be used to type out and display messages. Programs that predict words and sentences can speed up this method of communicating. Some indivduals are unable to read and have a computer system that uses symbols - they select a symbol and the printed word is produced. Voice output systems are similar to the computer setups already described but rather than having the printed word as output, the spoken word is produced. Simple devices have the ability to let an individual access a limited number of pre-recorded phrases by pushing the appropriate key.
More complex systems allow for creative productions.
Any of these systems can be used as a back-up by individuals who do have some functional speech. There are times when it is too tiring or too time-consuming to use speech. Then the alternative system is used. Most dysarthric speakers need more time to get their message across. It helps to allow them extra time and to listen face to face.
