Voice Output Communication Aids and Autism

Voice Output Communication Aids (VOCAs) or Speech Generating Devices (SGDs) are devices which enable the user to speak.

The simplest VOCAs store a single pre-recorded message, which is produced in the form of digitised speech when the person using the device presses a button, switch, or key.

The most elaborate VOCAs include software that allows users to create and combine words to produce novel utterances in the form of computerised synthetic speech.
