How to Write an Informative Speech for Public Speaking


As an informative public speaker, you will impart factual information through describing, demonstrating or explaining. You need to concentrate so you do not invoke personal opinion or persuasion. If you are free to choose your topic, it will be easier to select one on which you do not have a strong opinion, but, do not let your dispassionate stance translate into a boring speech. Remember, when writing your informative speech, your goal is to allow the audience to form their own opinions based on your facts.

  • Research your audience. Even though are you simply providing factual information, it will help you to know as much as possible about your audience's background, including previous their knowledge of and experience with the topic, as well as their education level. You do not want to talk down to them, but you do not want to assume they know more than they do and leave out basic information they need to formulate opinions or make decisions.

  • Write your introduction. This is your chance to get the audience's attention. Some effective tactics include using a famous quotation or offering a startling statistic. This is also the point in your speech where you want to establish your credibility, either as an expert on this particular topic or in some aspect of your professional career.

  • Select your thesis or angle. This is the main point of your speech, and narrows your topic. For example, if you are speaking on passenger air travel, your thesis might cover how passenger air travel has changed over the past 30 years.

  • Choose two to four important points to make in the body of your speech. These will provide the cornerstones of your audience's opinion-making. Using the example of your passenger air travel, your points of emphasis may be changes in service, fees, on-time records and safety. Expand upon these points as you write the body.

  • Organize your speech in an outline. Under each main point, write your supporting facts. Your outline will give you the structure you need to write your speech. More importantly, you can transfer your outline to note cards to refer to as you are speaking. This allows you to remain conversational, so you can engage the audience without reading from a prepared script.

  • Write your conclusion. Here you will summarize your main points, re-emphasizing what you want your audience to take away. Make it as memorable as your introduction. You can finish with another famous quote or a personal anecdote.

Tips & Warnings

  • Use words you normally use in daily conversations. Practice your speech until you are completely comfortable. Start your outline at any point in your speech writing process. Some speechwriters start in outline form to help them organize, while others write out portions of the speech and then condense and organize them in outline form. Do what works for you.
  • If you are given a podium, do not stay behind it the entire speech, as it keeps a barrier between you and your audience. Walk around the stage or front of the room.
