Which term describes the timing and control of speech production?

The term that best describes the timing and control of speech production is "speech fluency." Fluency refers to the flow of speech, including aspects such as the smoothness, rhythm, and timing of speech delivery. It encompasses various characteristics, such as the rate of speech, pausing patterns, and the ability to produce speech without excessive interruptions.

In contrast, while articulation pertains to the physical act of producing specific speech sounds, it does not necessarily address the timing aspect. Speech clarity focuses on the comprehensibility of the speech sounds but is more about the accuracy and precision of articulating those sounds. Speech modulation relates to the variation in pitch, loudness, and tone, impacting the expressiveness of speech but not specifically focusing on the timing and control involved in the fluency of speech production. Therefore, "speech fluency" specifically captures the essence of timing and control in the context of how speech is produced.
