11.1 Goals and Types of Informative Speeches

Informative speeches aim to educate and enlighten audiences on various topics. They require careful planning to present information objectively, bridge knowledge gaps, and stimulate curiosity. Speakers must consider audience needs and personal expertise when selecting topics.

Different types of informative speeches serve unique purposes. Descriptive speeches paint vivid pictures, explanatory speeches clarify complex ideas, and demonstrative speeches show how to do things. Historical and current events speeches provide context for past and present issues.
