Chapter 7: Presentations to Inform

46 Types of Presentations to Inform

Speaking to inform may fall into one of several categories. The presentation to inform may be

  • an explanation,
  • a report,
  • a description,
  • or a demonstration of how to do something.

In the sections below each of these types of informative speech will be described.


Have you ever listened to a lecture or speech where you just didn’t get it? It wasn’t that you weren’t interested, at least not at first. Perhaps the presenter used language you didn’t understand or gave a confusing example. Soon you probably lost interest and sat there, attending the speech in body but certainly not in mind. An effective speech to inform will take a complex topic or issue and explain it to the audience in ways that increase audience understanding.

No one likes to feel left out. As the speaker, it’s your responsibility to ensure that this doesn’t happen. Also know that to teach someone something new—perhaps a skill that they did not posses or a perspective that allows them to see new connections—is a real gift, both to you and the audience members. You will feel rewarded because you made a difference and they will perceive the gain in their own understanding.

As a business communicator, you may be called upon to give an informative report where you communicate status, trends, or relationships that pertain to a specific topic. The informative report is a speech where you organize your information around key events, discoveries, or technical data and provide context and illustration for your audience. They may naturally wonder, “Why are sales up (or down)?” or “What is the product leader in your lineup?” and you need to anticipate their perspective and present the key information that relates to your topic.


Have you ever listened to a friend tell you about their recent trip somewhere and found the details fascinating, making you want to travel there or visit a similar place? Describing information requires emphasis on language that is vivid, captures attention, and excites the imagination. Your audience will be drawn to your effective use of color, descriptive language, and visual aids. An informative speech that focuses description will be visual in many ways. Use your imagination to place yourself in their perspective: how would you like to have someone describe the topic to you?


You want to teach the audience how to program the applications on a new smartphone. A demonstrative speech focuses on clearly showing a process and telling the audience important details about each step so that they can imitate, repeat, or do the action themselves. Consider the visual aids or supplies you will need.

By considering each step and focusing on how to simplify it, you can understand how the audience might grasp the new information and how you can best help them. Also, consider the desired outcome; for example, will your listeners be able to actually do the task themselves? Regardless of the sequence or pattern you will illustrate or demonstrate, consider how people from your anticipated audience will respond, and budget additional time for repetition and clarification.
