Augmentative and Alternative Communication
An area of clinical practice that deals with communication problems of people who have complex communication needs
Complex Communication Needs
Problems may occur at any point across the life span
Speech & Language
When someone is not developing these skills or has lost these abilities, AAC intervention approaches are required to meet their CCN
Speech
Oral expression of language
Language
Consists of 5 Basic Elements
-Phonology, Morphology, Syntax, Semantics, and Pragmatics
Speech-Generating Devices
- Produce digitally recorded or synthesized speech output
- AAC tools that can significantly improve communication for individuals with CCN
Vocalization
- Production of sounds
- Can be an effective way of communicating things like yes and no, anger (screaming), happiness (laughing), sadness (crying), and getting attention
Dysarthria
Disorder of motor speech control resulting from central or peripheral nervous system damage that causes weakness, slowness, and a lack of coordination of the muscles necessary for speech production
Apraxia
(Verbal) A disorder affecting the coordination of motor movements involved in producing speech caused by a CNS dysfunction
Traditional Orthography
Symbols as the familiar alphabetic written language or it may be a set of pictographic symbols conveying meaning (ex. Hieroglyphics or other special symbols) or a set of hand movements (sign language) or gestures
Aphasia
- A type of language disorder that often occurs as a result of a stroke or TBI
- Can affect both expression and reception of spoken and written language
Amyotrophic Lateral Sclerosis
Degenerative diseases
Emergent Communicators
Have no reliable method of symbolic expression, and they know they are restricted to communicating about here-and-now concepts
Context-Dependent Communicators
Have reliable symbolic communication, but they are limited to specific contexts because they are either only intelligible to familiar partners, have insufficient vocab, or both
Independent Communicators
- Able to communicate with unfamiliar and familiar partners on any topic
- Each of these communicators has different needs and goals
