Which impairment affects a person’s ability to articulate their speech?

The choice that accurately reflects an impairment affecting a person's ability to articulate their speech is articulation. Articulation refers specifically to the physical ability to produce speech sounds. When someone has an articulation impairment, they may struggle with pronouncing words correctly, which can affect their clarity and intelligibility in spoken language. This encompasses issues like not being able to produce certain sounds, substituting one sound for another, or omitting sounds altogether.

Other terms like echolalia, aphasia, and alexia pertain to different aspects of language and communication. Echolalia is the repetition of phrases or noises made by others, aphasia involves difficulties with language comprehension or expression due to brain damage, and alexia relates to challenges with reading. Each of these conditions influences communication but does not specifically target the ability to articulate speech sounds like articulation does.
