What type of public speaking requires the participant to give a speech with little or no time for preparation?

Impromptu speaking is characterized by delivering a speech with minimal to no prior preparation. This style of speaking often occurs in situations where the speaker is called upon unexpectedly, such as in classroom settings or during meetings. The speaker must rely on their ability to think quickly and articulate their thoughts effectively on a given topic, often drawing on their existing knowledge and experience.

While prepared speaking involves careful planning and rehearsal, and extemporaneous speaking entails some preparation with a limited amount of time, impromptu speaking is distinct due to its spontaneous nature. Formal speaking refers to structured presentations, which also does not align with the lack of preparation typical in impromptu scenarios. Understanding these differences highlights the unique nature of impromptu speaking and its demand for quick thinking and adaptability.
