In every day life, sustained speech refers to the ability to speak continuously for an extended period of time without pausing or stopping. It is an important aspect of communication and is often used to give presentations or speeches, as well as to engage in conversation with others.
Sustained speech requires the ability to plan and organize your thoughts, and to effectively use vocalization and nonverbal communication to convey your ideas. It is typically associated with a clear and fluent speaking style, and it has a big impact on your TOEFL® Speaking score.
