The purpose of this paper is to introduce the general concepts of Augmentative and Alternative Communication (AAC). The paper includes a brief explanation of AAC, types of AAC, targeted populations benefitted by AAC, principles of a language-based service delivery, and a discussion of interdisciplinary team member roles.>Rehabilitation and related professions have grown rapidly in China during this decade.
