Augmentative and alternative communication (AAC) is an umbrella term that 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.

AAC is used by those with a wide range of speech and language impairments, including congenital impairments such as cerebral palsy, intellectual impairment and autism, and acquired conditions such as amyotrophic lateral sclerosis and Parkinson's disease.

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

Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.

Speech is the vocalized form of communication based upon the syntactic combination of lexicals and names that are drawn from very large (usually about 1,000 different words) vocabularies.

Each spoken word is created out of the phonetic combination of a limited set of vowel and consonant speech sound units (phonemes).

These vocabularies, the syntax that structures them, and their sets of speech sound units differ, creating many thousands of different, and mutually unintelligible, human languages.

Most human speakers are able to communicate in two or more of them, hence being polyglots.

The vocal abilities that enable humans to produce speech also enable them to sing.

Language is the ability to acquire and use complex systems of communication, particularly the human ability to do so, and a language is any specific example of such a system.

The scientific study of language is called linguistics.

Questions concerning the philosophy of language, such as whether words can represent experience, have been debated since Gorgias and Plato in Ancient Greece.

Thinkers such as Rousseau have argued that language originated from emotions while others like Kant have held that it originated from rational and logical thought.

20th-century philosophers such as Wittgenstein argued that philosophy is really the study of language.

Major figures in linguistics include Ferdinand de Saussure and Noam Chomsky.

A vocabulary is a set of familiar words within a person's language.

A vocabulary, usually developed with age, serves as a useful and fundamental tool for communication and acquiring knowledge.

Acquiring an extensive vocabulary is one of the largest challenges in learning a second language.
