What term describes the smoothness of speech?

Fluency is the term that refers to the smoothness of speech. When a person speaks fluently, they are able to express their thoughts clearly and without unnecessary pauses or interruptions, resulting in a rhythm and flow that enhances communication. This encompasses not only the ease with which an individual speaks but also their ability to convey ideas in a coherent and connected manner, making the listener's experience more engaging and understandable.

Other terms like clarity, articulation, and pronunciation focus on specific aspects of speech. Clarity emphasizes how understandable the speech is, rather than the overall smoothness. Articulation refers to the physical ability to produce distinct sounds and words, which is more about the precision of individual speech sounds. Pronunciation involves the correct formation of words, indicating how they are said. While all these factors contribute to effective communication, fluency specifically captures the essence of smooth and effortless speech.
