Page "Assistive technology" Paragraph 12

A great diversity of diagnoses, including cerebral palsy, intellectual impairment, autism, and many others, cover varying degrees of communication impairment.

AAC interventions are highly individualized, taking into account specific abilities of language comprehension, social-relational characteristics, learning strengths and weaknesses, and developmental patterns for specific types of intellectual disabilities.

AAC can be used to aid both spoken and written language, and can supplement or replace speech and writing as necessary.

AAC can be a permanent addition to a person's communication or a temporary aid.

The systems used in AAC include gestures, hand signals, photographs, pictures, line drawings, words and letters, which can be used alone or in combination to communicate.
