How is the ability to speak clearly and distinctly referred to?

The ability to speak clearly and distinctly is best referred to as articulation. This term specifically focuses on how sounds are formed and how words are pronounced clearly, allowing for effective communication. Proper articulation involves the precise pronunciation of sounds, ensuring that each word is intelligible and easy to understand.

Enunciation, while related, typically emphasizes clarity and style in pronunciation rather than the phonetic aspects of how sounds are formed. Pronunciation refers more broadly to the way in which words are spoken, which can encompass regional accents or variations. Fluency generally pertains to the smoothness and flow of speech rather than the clarity of individual sounds or words. Thus, articulation is the most accurate term to describe the specific skill of speaking clearly and distinctly.
