Augmentative communication (AC) is a way for a child to communicate when the child does not have the physical ability to use speech or writing. AC can be high tech, such as a computer that is programmed to talk for the child. AC can also be low tech by using simple pictures, sign language or a device that plays recorded messages. Speech-language pathologists may help the child to use a picture exchange communication system (PECS).
Children can use AC for a short time while speech skills are developing, or for their entire life.
