What characterizes an impromptu speech?

An impromptu speech is characterized by being delivered spontaneously and without prior preparation or advance notice. This type of speech demands quick thinking and adaptability from the speaker, as they must organize their thoughts and convey them effectively on the spot. The speaker may need to rely on their existing knowledge of the topic at hand, making it essential to have a good understanding of a variety of subjects.

In contrast, an outlined and rehearsed presentation involves thorough preparation, including structured points and practice sessions. A speech delivered in a formal setting often follows specific protocols and guidelines, which is not a prerequisite for an impromptu speech. Similarly, a presentation that requires visual aids indicates planned content and the need for additional materials, which is not a feature of impromptu speaking. The essence of an impromptu speech is the ability to think and communicate clearly without the security of preparation, which distinguishes it from other forms of public speaking.
