Welcome to the Penn State Augmentative
and Alternative Communication Website!
About AAC
Did you know that there are approximately two million people in the United States who have
significant speech and/or writing impairments and need to use Augmentative and Alternative
Communication (AAC)?
Benefits of AAC
Without access to functional speech, these individuals are severely restricted in their
participation in educational, vocational, home and community activities. AAC offers the potential
to enhance communication and increase participation. AAC includes gestures, signs, communication
boards with photographs or line drawings, alphabet boards, and computer-based assistive
technologies.
