What follows are four methods of delivery that can help you balance between too much and too little formality when giving a speech. Each has its own strengths and weaknesses, but you will most likely want to focus on the extemporaneous approach, since that is probably what your instructor will want from you.

Impromptu Speaking

Impromptu speaking is the presentation of a short message without advance preparation. You have probably done impromptu speaking many times in informal, conversational settings. Self-introductions in group settings are examples of impromptu speaking: “Hi, my name is Steve, and I’m a volunteer with the Homes for the Brave program.” Another example of impromptu speaking occurs when you answer a question such as “What did you think of the movie?” Your response has not been preplanned, and you are constructing your arguments and points as you speak. Even worse, you might find yourself going into a meeting and your boss says, “I want you to talk about the last stage of the project. . .”  and you have no warning.

The advantage of this kind of speaking is that it’s spontaneous and responsive in an animated group context. The disadvantage is that the speaker is given little or no time to contemplate the central theme of his or her message. As a result, the message may be disorganized and difficult for listeners to follow.

Here is a step-by-step guide that may be useful if you are called upon to give an impromptu speech in public:

1. Take a moment to collect your thoughts and plan the main point or points you want to make.
2. Thank the person for inviting you to speak. Do not make comments about being unprepared, called upon at the last moment, on the spot, or uneasy. No one wants to hear that, and it will embarrass others and yourself.
3. Deliver your message, making your main point as briefly as you can while still covering it adequately and at a pace your listeners can follow.
4. Stay on track. Answer the question or prompt as given; resist the temptation to go elsewhere.
5. If you can, use a structure, using numbers if possible: “Two main reasons . . .” or “Three parts of our plan. . .” or “Two side effects of this drug. . .” Past, present, and future or East Coast, Midwest, and West Coast are common structures.
6. Thank the person again for the opportunity to speak.
7. Stop talking (it is easy to “ramble on” when you don’t have something prepared). If in front of an audience, don’t keep talking as you move back to your seat.

Impromptu speeches are generally most successful when they are brief and focus on a single point.

Manuscript Speaking

Manuscript speaking is the word-for-word iteration of a written message. In a manuscript speech, the speaker maintains his or her attention on the printed page except when using visual aids. The advantage to reading from a manuscript is the exact repetition of original words. In some circumstances this can be extremely important. For example, reading a statement about your organization’s legal responsibilities to customers may require that the original words be exact. In reading one word at a time, in order, the only errors would typically be mispronunciation of a word or stumbling over complex sentence structure. A manuscript speech may also be appropriate at a more formal affair (like a funeral), when your speech must be said exactly as written in order to convey the proper emotion or decorum the situation deserves.

However, there are costs involved in manuscript speaking. First, it’s typically an uninteresting way to present. Unless the speaker has rehearsed the reading as a complete performance animated with vocal expression and gestures (well-known authors often do this for book readings), the presentation tends to be dull. Keeping one’s eyes glued to the script prevents eye contact with the audience. For this kind of “straight” manuscript speech to hold audience attention, the audience must be already interested in the message and speaker before the delivery begins.

It is worth noting that professional speakers, actors, news reporters, and politicians often read from an autocue device, such as a TelePrompTer, especially when appearing on television, where eye contact with the camera is crucial. With practice, a speaker can achieve a conversational tone and give the impression of speaking extemporaneously and maintaining eye contact while using an autocue device. However, success in this medium depends on two factors: (1) the speaker is already an accomplished public speaker who has learned to use a conversational tone while delivering a prepared script, and (2) the speech is written in a style that sounds conversational and in spoken rather than written, edited English, for example, with shorter sentences and clearer transitions.

For the purposes of your public speaking class, you will likely not be allowed to read your speech. Instead, you will be assigned to give an extemporaneous presentation.

Extemporaneous Speaking

Extemporaneous speaking is the presentation of a carefully planned and rehearsed speech, spoken in a conversational manner using brief notes. By using notes rather than a full manuscript, the extemporaneous speaker can establish and maintain eye contact with the audience and assess how well they are understanding the speech as it progresses. And since you will be graded (to some degree) on establishing and maintaining eye contact with your audience, extemporaneous speaking can be extremely beneficial in that regard. Without all the words on the page to read, you have little choice but to look up and make eye contact with your audience. In some cases, your instructor will require you to prepare strong preparation and speaking (notes) outlines as a foundation for your speech; this topic is addressed in Chapter 6.

Speaking extemporaneously has some advantages. It promotes the likelihood that you, the speaker, will be perceived as knowledgeable and credible since you know the speech well enough that you don’t need to read it. In addition, your audience is likely to pay better attention to the message because it is engaging both verbally and nonverbally. It also allows flexibility; you are working from the strong foundation of an outline, but if you need to delete, add, or rephrase something at the last minute or to adapt to your audience, you can do so. The outline also helps you be aware of main ideas vs. subordinate ones.

Adequate preparation cannot be achieved the day before you’re scheduled to speak, so be aware that if you want to present a credibly delivered speech, you will need to practice many times. Because extemporaneous speaking is the style used in the great majority of public speaking situations, most of the information in the subsequent sections of this chapter is targeted toward this kind of speaking.

Memorized Speaking

Memorized speaking is the rote recitation of a written message that the speaker has committed to memory. Actors, of course, recite from memory whenever they perform from a script. When it comes to speeches, memorization can be useful when the message needs to be exact and the speaker doesn’t want to be confined by notes.

The advantage to memorization is that it enables the speaker to maintain eye contact with the audience throughout the speech. Being free of notes means that you can move freely around the stage and use your hands to make gestures. If your speech uses visual aids, this freedom is even more of an advantage.

However, there are some real and potential costs. First, unless you also plan and memorize every vocal cue (the subtle but meaningful variations in speech delivery, which can include the use of pitch, tone, volume, and pace), gesture, and facial expression, your presentation will be flat and uninteresting, and even the most fascinating topic will suffer. You might end up speaking in a monotone or a sing-song repetitive delivery pattern. You might also present your speech in a rapid “machine-gun” style that fails to emphasize the most important points.

Second, if you lose your place and start trying to ad lib, the contrast in your style of delivery will alert your audience that something is wrong. If you go completely blank during the presentation, it will be extremely difficult to find your place and keep going. Obviously, memorizing a typical classroom speech takes a great deal of time and effort, and if you aren’t used to memorizing, it is very difficult to pull off. Realistically, you probably will not have the time necessary to give a completely memorized speech. However, if you practice adequately, you will approach the feeling of memorization while still being extemporaneous.

As we said earlier, for the purposes of this class you will use extemporaneous speaking. Many professional speakers who are paid to make speeches use this approach because, while they may largely know what they want to say, they usually make changes and adjustments based on the audience or event. This approach also incorporates most of the benefits of memorized speaking (knowing what you want to say; being very thoroughly rehearsed) and manuscript speaking (having some words in front of you to refer to) without the inherent pitfalls those approaches bring with them.
