What type of speech is often characterized by a short preparation period?

Impromptu speeches are known for their spontaneous nature, requiring speakers to prepare quickly on a topic, often with little to no prior notice. This type of speech helps develop critical thinking and quick organizational skills, as the speaker must formulate their thoughts and present them coherently on the spot. Impromptu speaking typically occurs in settings like meetings, debates, or classroom discussions, where rapid response to questions or prompts is necessary.

In contrast, informative speeches usually involve research and a longer preparation period since the goal is to educate the audience on a specific topic with detailed information. Persuasive speeches aim to convince the audience of a particular viewpoint, often requiring substantial preparation to effectively argue and support the position taken. Demonstrative speeches involve showing the audience how to perform a task or operation, necessitating advance preparation to ensure accuracy and clarity.
