What is Augmentative Communication?

According to Dell, Newton, and Petroff, authors of Assistive Technology in the Classroom, "augmentative communication is a way to supplement an individual's method of communication to assist comprehension" (2012).  Typically, augmentative communication devices are used to help individuals who cannot speak to interact and communicate with others.  These devices and systems are important and necessary because they allow individuals to express themselves and communicate with peers, as well as increases their independence and creates numerous opportunities (Dell, Newton, Petroff, 2012).

There are two types of augmentative communication systems: unaided and aided.
