Appropriate and Colorful Language

• While a speaker should avoid assuming her audience is familiar with complex or technical terms, if she is speaking in front of a group of doctors, it is relatively safe to assume they know what hemoglobin is or what a pancreas does. Using appropriate language that fits your audience helps the speaker avoid "talking down" or misjudging an audience. Colorful language is equally important. If a speaker's information is bland and boring, her audience will quickly lose interest. Including colorful, descriptive language in informative passages is a trick journalists have been using for generations because it keeps audiences engaged during the most dense information.
  
  

Emphatic Body Language

• Body language can make a big difference in informative speaking, regardless of whether the speaker is chatting with a few associates or making a formal speech to a hundred people. Body language helps punctuate speech -- it conveys importance and emotion and can even reinforce key ideas. Informative speaking is about comprehension and understanding as much as it is about the raw information. Emphasizing and clarifying key ideas with appropriate body language can make a speech both more interesting and easier to follow along.
  
  

Interest in the Subject Matter

• Enthusiasm shows. If a speaker is interested and engaged in the issue he is speaking about, he will demonstrate that to the audience. But, even if the subject of an informative discussion is something as lackluster as budget allocation or the mating rituals of sea slugs, a speaker can still project an interest in the subject matter. The best way to get an audience to pay attention to a less-than-stellar topic is to show the audience why they should care about the issue. Successful informative speakers demonstrate to their audience that their topic is one worth their time and attention.
  
  

Narratives and Detail

• Informative speaking thrives on good narratives. Anecdotes to flesh out the issue at hand, colorful premises that set the scene for a speaker's subject matter or analogies that clarify important points are all examples of ways to integrate narrative structure into informative speaking. Any speaker that simply recites facts will have a far more difficult time than someone who provides an audience with contextual examples to help explain those facts and make them more memorable. Giving an audience good detail in a speech sometimes means taking a step away from the big picture to explain an issue on an individual scale.
