An AAC user indicates a series of numbers on an eye gaze communication board in order to convey a word. Augmentative and alternative communication (AAC) encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production or comprehension of spoken or written language.
Speech-generating devices (SGDs), also known as voice output communication aids, are electronic augmentative and alternative communication (AAC) systems used to supplement or replace speech or writing for individuals with severe speech impairments, enabling them to verbally communicate. [1]
Tangible symbols are a type of augmentative and alternative communication (AAC) that uses objects or pictures that share a perceptual relationship with the items they represent as symbols. A tangible symbol's relation to the item it represents is perceptually obvious and concrete – the visual or tactile properties of the symbol resemble the ...
Partner-assisted scanning is a technique used with children who have severe motor and communication impairments, and especially those with additional visual impairment, those who do not yet have an established alternative form of communication, or who are unable to use their usual method, perhaps because their electronic speech output device is being repaired.

[30] [31] AAC devices can be no-tech (sign language and body language), low-tech (picture boards, paper and pencils), or high-tech (tablets and speech generating devices). [29] The choice of AAC device is very important and should be determined on a case-by-case basis by speech therapists and assistive technology professionals.
Semantic compaction, (Minspeak), conceptually described as polysemic (multi-meaning) iconic encoding, is one of the three ways to represent language in Augmentative and alternative communication (AAC). [1] It is a system utilized in AAC devices in which sequences of icons (pictorial symbols) are combined in order to form a word or a phrase.
[3] [7] Communication during scanning is slower and less efficient than direct selection and scanning requires more cognitive skill (e.g., attention). [ 4 ] [ 5 ] Scanning using technology has an advantage allows the user to be independent in controlling the assistive technology for those with only one voluntary movement.
Speech-language pathologists create plans that cater to the individual needs of the patient. If speech is not practical for a patient, the SLP will work with the patient to decide upon an augmentative and alternative communication (AAC) method or device to facilitate communication. They may work with other patients to help them make sounds ...
