Public Speaking

The medium transmits a speaker’s message. When public speaking takes place in a direct, face-to-face encounter, the medium is the air through which the sound travels. When a speech is presented outside or in a large auditorium, a microphone and amplifiers may be part of the medium. We tend to take the medium for granted until we discover something wrong with it, like poor acoustics. Public speeches can also be transmitted through the electronic media of radio, television, and video-or-audiotapes. The electronic media have major effects on the entire communication process. For example, radio emphasizes the attractiveness, clarity, and expressiveness of a speaker’s voice. Television brings a speaker into a close relationship with viewers, so personality and physical appearance take on added importance. When speakers want news coverage, they must compress important ideas into twenty-second sound bites, and the language must be immediately clear and colorful. Any change in the medi...

A speech occurs within a physical and psychological setting that can determine how well it succeeds. The physical setting in which a speech is presented can include such factors as the time the speech is given; the time allotted for the presentation the pace of the presentation, and the size and arrangement of the audience. For example, when speaking outside, a speaker may need a more forceful presentation than when speaking in a small room. A larger audience may require a more formal manner of presentation than a smaller audience. The very quality of the physical setting can affect the speech. For example, one of the most profound discussions of the ethics of communication, Plato’s Pbaedrus, written in ancient Greece some 2,400 years ago, takes place in a woodland setting that frames and colors its message appropriately. In this setting, Socrates envisions an ideal communication that promotes spiritual growth for both listeners and speakers. One classroom setting in which we ta...

A constructive listener is supportive yet listens carefully and critically. Such listeners seek the value in all messages. Because the fate of a message depends on how listeners respond to it, the audience must be at the center of your thinking as you plan, prepare, and present your speeches. What needs or problems concern them? What subjects interest them? What biases could distort their reception of message? Such questions are crucial to the selection of your topic and to the way you frame your message. Moreover, you should be sensitive to the fact that your words could affect the lives of listeners and even their perception of themselves. Listeners do not come to a speech with a blank slate. Their minds are filled with past experiences, information or misinformation about a topic or speaker, attitudes and values, aspirations and fears. All of these factors form the frame of reference that a listener brings to a speech. The better you understand these audience factors, the more...

The response to a speech is what happens during and as a result of the speech. Of course you hope that your speeches are well received and that they will affect the lives of your listeners favorably. But whether they achieve that result depends a great deal on what happens during the speech. One of the things that make public speaking dynamic is its interactive quality. While you are speaking, listeners are responding. As they respond, so should you. This makes a speech an interaction in which listeners and speakers constantly adjust to each other. These on-the-spot adjustments lend an unpredictable quality to public speaking that can make it an interesting and exciting form of communication. Note the adjustment that one of our speakers made during a speech on the dangers of global warming; Some of you are frowning, and I can hardly blame you. This is really hard to believe. But let me quote to you the words of Time magazine in a recent survey of all these scientific disc...

Interference can enter at any point in the process to disrupt the effectiveness of communication. Interference, which we discuss further in Chapter 3, can range from physical noise that impedes the hearing of a speech, such as a plane flying over the building, to psychological “noise” within speakers and listeners that prevents them from connecting. Three forms of interference are especially troubling. The first is speaker apprehension. Fear is an understandable reaction to public speaking experiences. The situation may seem strange, and speakers may feel exposed and vulnerable. Listeners may seem distant, unfriendly, or threatening. Beginning speakers will learn to control their fears and to convert them into positive energy that adds sparkle and power to a speech. But at the outset, these feelings can interfere with effective communication. A second form of interference is listener distraction, which imposes a barrier between an audience and a message. Listene...

Successful speeches obviously have impact. As a result of them, listeners learn, decide to change their minds or to take action, or join in celebrating the meaning of exemplary lives. Moreover, if we could see the communication process at work in a speech, we might also see the identities of speakers and listeners coming into or out of focus of communication or show those same people growing larger or smaller. These effects would all represent the consequences of public speaking, especially the ethical impact of public speaking as transactional and transformational communication. Transactional communication suggests that successful communication goes beyond personal achievement and the sharing of vital information, ideas, and advice. It implies the sharing and sharing of sieves. In the introduction to Bridges Nor Walls, John Stewart, an interpersonal communication scholar, notes: “Every time persons communicate, they are continually offering definitions of themselve...

The materials used to support a speaker’s ideas. The skillful use of Supporting Materials often makes the difference between a poor speech and a good one. It is also closely related to Critical Thinking. Using supporting materials is not a matter of haphazardly tossing facts and figures into your speech. You must decide which ideas need to be supported, give your audience, topics and specific purpose. You must to research to find materials that will being your ideas across clearly and creatively. And you must evaluate your supporting materials to make sure they really do back up your ideas. As you put your speeches together, you will need to make sure your supporting materials are accurate, relevant, and reliable. You will find yourself asking questions such as “Are my example representative?” “Am I using statistical measures correctly?” “Am I quoting reputable, qualified sources?” Assessing the supporting materials in your speech – as well as in your speech of your classmates—is...
