What is the term for the rapid alternating movements of the jaw, tongue, lips, teeth, and soft palate necessary for speech?

Articulation refers to the precise movements involved in producing speech sounds. This term encompasses the rapid, coordinated motions of the jaw, tongue, lips, teeth, and soft palate that are crucial for clear and understandable communication. Effective articulation allows individuals to form words and phrases correctly by manipulating these speech organs in a way that produces recognizable sounds.

The other terms do not directly describe the physical actions involved in producing speech. Dysarthria denotes a speech disorder resulting from muscle weakness, impacting clarity rather than the act of producing sounds itself. Dyspraxia, also known as developmental coordination disorder, involves challenges with planning and executing movements, which can affect speech but is a broader term that applies to various motor tasks. Semantics relates to meaning in language rather than the mechanics of speech production. Thus, articulation is the most appropriate term for the rapid movements necessary for speech.
