What are the three main types of articulators?

• A. Active, passive, and fixed
• B. Dynamic, static, and mobile
• C. Primary, secondary, and tertiary
• D. Fast, slow, and average

Answer: (A)

The three main types of articulators are best represented as active, passive, and fixed. Active articulators refer to the structures that move to produce speech sounds, such as the tongue and the lips. These are crucial for the creation of various phonetic sounds, as they actively engage in the process of articulation.

Passive articulators are those that do not move but act as points of contact for the active articulators. Examples include the hard palate and the teeth, which serve as surfaces against which the active articulators can make contact to produce sounds.

Fixed articulators typically refer to structures that do not change position during articulation, serving as stable points within the vocal tract. Together, these categories help in understanding how speech sounds are produced by utilizing various anatomical structures and their movements or lack thereof.

The other answer choices do not accurately represent the primary categories of articulators in the context of speech sound production. Dynamic, static, and mobile do not capture the interaction of movement between articulators, while primary, secondary, and tertiary, alongside fast, slow, and average, do not relate to the functional aspects of anatomical structures involved in articulation.
