Speech output devices may not be a good way to teach nonverbal children with autism to speak.
This study was designed to see if speech output devices (synthetic speech) help five children (aged 8-10) with autism learn to speak. The main focus was on teaching the children to learn how to make requests. The study showed no big difference between when the children were given a speech output device and when they were not. Some children did do slightly better with the speech output device. Only one of the five children showed improved speech at the end of the study.
