What is the term for the act or manner of producing sounds?

The term for the act or manner of producing sounds is articulation. Articulation refers to the clarity and effectiveness with which sounds, words, and phrases are pronounced or spoken. It encompasses the physical movements of the tongue, lips, and other speech organs that create sound. In the context of language education, a strong focus on articulation is crucial, as it directly impacts a person's ability to communicate effectively and be understood by others.

The other terms, while related to language or communication, denote different concepts. Echolalia refers to the repetition of sounds or phrases, often seen in some developmental conditions. Lexicon pertains to the vocabulary of a language or an individual, while hyperlexia describes an advanced ability to read at an early age, often without full comprehension. These terms address specific aspects of language and communication rather than the general act of sound production that articulation represents.
