Write 10 pages with APA style on Augmentative and alternative means of communication for teaching students with severe disabilities. American Speech-Language-Hearing Association has identified that “there are over 2 million individuals in the United States who cannot reply on speech as their primary means of communication” (Vinson, 2001, p. 139). This statistics reveal the scope and importance of AAC in the United States. These learners are subjected to various types of cognitive and physical deficits which add to their speech deficits in their developmental period. It has been identified that other systems of augmentative and alternative communication, such as gestures, sign language, picture or word boards, alphabet boards, and systems with synthesized or digitized speech are better suited for such students with severe disabilities. The rights of students with severe disabilities have long been recognized. There have been a good number of legislations that sought to address the issue of teaching students with severe disability through various augmentative and alternative communication means.
