Tailor the level of abstraction to the specific content and the audience level of understanding.
Making use of facial expressions and body gestures help in increasing the impact of your argument. Depending on the time limit, you will need to restrict yourself to some basic information, or you can choose to focus on one part of the topic. This type of speech involves the use of demonstrations, descriptions, definitions, and details to explain a topic, person, or place.
When groups of words are ranked according to degree of abstraction, they form hierarchies. Ideally, not only are they informed while you are speaking, but they actually retain that information after you have left the podium. Because of this, you would want to tailor the complexity of the speech to match the knowledge that the audience already possesses, meaning that the speech could contain lots of technical terms with little explanation because the audience will already understand what those terms mean.
Become comfortable with your keywords to the point that what you say takes the form of an easy, natural conversation. Questions like, how do you ensure that you pick the right topic, how do you draft such a speech, how do you ensure that you have a perfect introduction, and how do you ensure that you have the attention of the audience, abound in your head.
With visual aids, a speaker needs to make sure they adequately enhance the presentation without causing a distraction for the audience. Making a topic relevant for your audience increases the likelihood that they will remember the information contained in your speech.
Ladder: Think of abstraction as a ladder. Scoping a speech is not only helpful for the audience, but is also to the benefit of the speaker. Conversely, consider delivering a speech on the same topic to an audience of college students.
