What defines 'impromptu speaking'?

Impromptu speaking is characterized by the delivery of a speech or message without any prior preparation or notice. This form of speaking often requires the speaker to think quickly and articulate their thoughts spontaneously, allowing them to demonstrate their ability to organize their ideas verbally in the moment. The essence of impromptu speaking lies in its immediacy and the challenge of conveying effective communication without the aid of notes or extensive planning.

In contrast, structured speeches rely on careful planning and organization, often involving the use of notes to guide the presentation. Presentations that require extensive preparation are not aligned with the concept of impromptu speaking, as they demand a level of forethought absent in spontaneous speaking. Visual aids can enhance a presentation, but impromptu speaking typically does not involve any reliance on these tools since it is focused on one's ability to communicate effectively in an unprepared context. Thus, the nature of impromptu speaking is best captured by the description of delivering a brief message without advance preparation.
