What term describes the clarity and effectiveness of speech delivery?

Articulation refers specifically to the clarity and distinctness with which sounds and words are produced in speech. It encompasses the precise formation of sounds and the clear pronunciation of words, which is crucial for ensuring that an audience can easily understand the speaker's message. Effective articulation contributes significantly to the overall effectiveness of speech delivery, allowing speakers to convey their ideas without ambiguity or confusion.

Eloquent delivery emphasizes a style of speaking that is persuasive and expressive, but does not specifically address clarity. Fluency pertains to the smoothness and flow of speech, which can impact delivery but is not solely focused on clarity. Enunciation, while related to articulation, more specifically involves pronouncing words clearly and correctly; however, it does not encompass the full breadth of clarity in communication that articulation provides. Thus, articulation is the most appropriate term to describe the clarity and effectiveness of speech delivery.
