Volume

Volume refers to the loudness or softness of a speaker’s voice. As mentioned, public speakers need to speak loudly enough to be heard by everyone in the audience. In addition, volume is often needed to overcome ambient noise, such as the hum of an air conditioner or the dull roar of traffic passing by. In addition, you can use volume strategically to emphasize the most important points in your speech. Select these points carefully; if you emphasize everything, nothing will seem important. You also want to be sure to adjust your volume to the physical setting of the presentation. If you are in a large auditorium and your audience is several yards away, you will need to speak louder. If you are in a smaller space, with the audience a few feet away, you want to avoid overwhelming your audience with shouting or speaking too loudly.

Rate

Rate is the speed at which a person speaks. To keep your speech delivery interesting, your rate should vary. If you are speaking extemporaneously, your rate will naturally fluctuate. If you’re reading, your delivery is less likely to vary. Because rate is an important tool in enhancing the meanings in your speech, you do not want to give a monotone drone or a rapid “machine-gun” style delivery. Your rate should be appropriate for your topic and your points. A rapid, lively rate can communicate such meanings as enthusiasm, urgency, or humor. A slower, moderated rate can convey respect, seriousness, or careful reasoning. By varying rapid and slower rates within a single speech, you can emphasize your main points and keep your audience interested.

Pitch

Pitch refers to the highness or lowness of a speaker’s voice. Some speakers have deep voices and others have high voices. As with one’s singing voice range, the pitch of one’s speaking voice is determined to a large extent by physiology (specifically, the length of one’s vocal folds, or cords, and the size of one’s vocal tract). We all have a normal speaking pitch where our voice is naturally settled, the pitch where we are most comfortable speaking, and most teachers advise speaking at the pitch that feels natural to you.

While our voices may be generally comfortable at a specific pitch level, we all have the ability to modulate, or move, our pitch up or down. In fact, we do this all the time. When we change the pitch of our voices, we are using inflections. Just as you can use volume strategically, you can also use pitch inflections to make your delivery more interesting and emphatic. If you ordinarily speak with a soprano voice, you may want to drop your voice to a slightly lower range to call attention to a particular point. How we use inflections can even change the entire meaning of what we are saying. For example, try saying the sentence “I love public speaking” with a higher pitch on one of the words—first raise the pitch on “I,” then say it again with the pitch raised on “love,” and so on. “I love public speaking” conveys a different meaning from “I love public speaking,” doesn’t it?

There are some speakers who don’t change their pitch at all while speaking, which is called monotone. While very few people are completely monotone, some speakers slip into monotone patterns because of nerves. One way to ascertain whether you sound monotone is to record your voice and see how you sound. If you notice that your voice doesn’t fluctuate very much, you will need to be intentional in altering your pitch to ensure that the emphasis of your speech isn’t completely lost on your audience.

Finally, resist the habit of pitching your voice “up” at the ends of sentences. It makes them sound like questions instead of statements. This habit can be disorienting and distracting, interfering with the audience’s ability to focus entirely on the message. The speaker sounds uncertain or sounds as though he or she is seeking the understanding or approval of the listener. It hurts the speaker’s credibility and it needs to be avoided.

The effective use of pitch is one of the keys to an interesting delivery that will hold your audience’s attention.

Pauses

Pauses are brief breaks in a speaker’s delivery that can show emphasis and enhance the clarity of a message. In terms of timing, the effective use of pauses is one of the most important skills to develop. Some speakers become uncomfortable very quickly with the “dead air” that the pause causes. And if the speaker is uncomfortable, the discomfort can transmit itself to the audience. That doesn’t mean you should avoid using pauses; your ability to use them confidently will increase with practice. Some of the best comedians use the well-timed pause to powerful and hilarious effect. Although your speech will not be a comedy routine, pauses are still useful for emphasis, especially when combined with a lowered pitch and rate to emphasize the important point you do not want your audience to miss.

Vocal Variety

Vocal variety has to do with changes in the vocalics we have just discussed: volume, pitch, rate, and pauses. No one wants to hear the same volume, pitch, rate, or use of pauses over and over again in a speech. Your audience should never be able to detect that you’re about to slow down or your voice is going to get deeper because you’re making an important point. When you think about how you sound in a normal conversation, your use of volume, pitch, rate, and pauses are all done spontaneously. If you try to overrehearse your vocalics, your speech will end up sounding artificial. Vocal variety should flow naturally from your wish to speak with expression. In that way, it will animate your speech and invite your listeners to understand your topic the way you do.

Pronunciation

The last major category related to vocalics is pronunciation, or the conventional patterns of speech used to form a word. Word pronunciation is important for two reasons: first, mispronouncing a word your audience is familiar with will harm your credibility as a speaker; and second, mispronouncing a word they are unfamiliar with can confuse and even misinform them. If there is any possibility at all that you don’t know the correct pronunciation of a word, find out. Many online dictionaries, such as the Wiktionary, provide free sound files illustrating the pronunciation of words.

Many have commented on the mispronunciation of words such as “nuclear” and “cavalry” by highly educated public speakers, including US presidents. There have been classroom examples as well. For instance, a student giving a speech on the Greek philosopher Socrates mispronounced his name at least eight times during her speech. This mispronunciation created a situation of great awkwardness and anxiety for the audience. Everyone felt embarrassed and the teacher, opting not to humiliate the student in front of the class, could not say anything out loud, instead providing a private written comment at the end of class.

One important aspect of pronunciation is articulation, or the ability to clearly pronounce each of a succession of syllables used to make up a word. Some people have difficulty articulating because of physiological problems that can be treated by trained speech therapists, but other people have articulation problems because they come from a cultural milieu where a dialect other than standard American English is the norm. Speech therapists, who generally guide their clients toward standard American English, use the acronym SODA when helping people learn how to more effectively articulate: substitutions, omissions, distortions, and additions.

• Substitutions occur when a speaker replaces one consonant or vowel with another consonant (water becomes wudda; ask becomes ax; mouth becomes mouf).
• Omissions occur when a speaker drops a consonant or vowel within a word (Internet becomes Innet; mesmerized becomes memerized; probably becomes prolly).
• Distortions occur when a speaker articulates a word with nasal or slurring sounds (pencil sounds like mencil; precipitation sounds like persination; second sounds like slecond).
• Additions occur when a speaker adds consonants or vowels to words that are not there (anyway becomes anyways; athletic becomes athaletic; black becomes buhlack; interpret becomes interpretate).

Another aspect of pronunciation in public speaking is avoiding the use of verbal surrogates or “filler” words used as placeholders for actual words (like er, um, uh, etc.). You might be able to get away with saying “um” as many as two or three times in your speech before it becomes distracting, but the same cannot be said of “like.” We know of a student who trained herself to avoid saying “like.” As soon as the first speech was assigned, she began wearing a rubber band on her left wrist. Each time she caught herself saying “like,” she snapped herself with the rubber band. It hurt. Very quickly, she found that she could stop inflicting the snap on herself, and she had successfully confronted an unprofessional verbal habit.

Posture

“Stand up tall!” I’m sure we’ve all heard this statement from a parent or a teacher at some point in our lives. The fact is, posture is actually quite important. When you stand up straight, you communicate to your audience, without saying a word, that you hold a position of power and take your position seriously. If however, you are slouching, hunched over, or leaning on something, you could be perceived as ill prepared, anxious, lacking in credibility, or not serious about your responsibilities as a speaker. While speakers often assume more casual posture as a presentation continues (especially if it is a long one, such as a ninety-minute class lecture), it is always wise to start by standing up straight and putting your best foot forward. Remember, you only get one shot at making a first impression, and your body’s orientation is one of the first pieces of information audiences use to make that impression.

Body Movement

Unless you are stuck behind a podium because of the need to use a nonmovable microphone, you should never stand in one place during a speech. However, movement during a speech should also not resemble pacing. One of our authors once saw a speaker who would walk around a small table where her speaking notes were located. She would walk around the table once, toss her chalk twice, and then repeat the process. Instead of listening to what the speaker was saying, everyone became transfixed by her walk-and-chalk-toss pattern. As speakers, we must be mindful of how we go about moving while speaking. One common method for easily integrating some movement into your speech is to take a few steps any time you transition from one idea to the next. By only moving at transition points, not only do you help focus your audience’s attention on the transition from one idea to the next, but you also are able to increase your nonverbal immediacy by getting closer to different segments of your audience.

Body movement also includes gestures. These should be neither overdramatic nor subdued. At one extreme, arm-waving and fist-pounding will distract from your message and reduce your credibility. At the other extreme, refraining from the use of gestures is the waste of an opportunity to suggest emphasis, enthusiasm, or other personal connection with your topic.

There are many ways to use gestures. The most obvious are hand gestures, which should be used in moderation at carefully selected times in the speech. If you overuse gestures, they lose meaning. Many late-night comedy parodies of political leaders include patterned, overused gestures or other delivery habits associated with a particular speaker. However, the well-placed use of simple, natural gestures to indicate emphasis, direction, size is usually effective. Normally, a gesture with one hand is enough. Rather than trying to have a gesture for every sentence, use just a few well-planned gestures. It is often more effective to make a gesture and hold it for a few moments than to begin waving your hands and arms around in a series of gestures.

Finally, just as you should avoid pacing, you will also want to avoid other distracting movements when you are speaking. Many speakers have unconscious mannerisms such as twirling their hair, putting their hands in and out of their pockets, jingling their keys, licking their lips, or clicking a pen while speaking. As with other aspects of speech delivery, practicing in front of others will help you become conscious of such distractions and plan ways to avoid doing them.

Facial Expressions

Faces are amazing things and convey so much information. As speakers, we must be acutely aware of what our face looks like while speaking. While many of us do not look forward to seeing ourselves on videotape, often the only way you can critically evaluate what your face is doing while you are speaking is to watch a recording of your speech. If video is not available, you can practice speaking in front of a mirror.

There are two extremes you want to avoid: no facial expression and overanimated facial expressions. First, you do not want to have a completely blank face while speaking. Some people just do not show much emotion with their faces naturally, but this blankness is often increased when the speaker is nervous. Audiences will react negatively to the message of such a speaker because they will sense that something is amiss. If a speaker is talking about the joys of Disney World and his face doesn’t show any excitement, the audience is going to be turned off to the speaker and his message. On the other extreme end is the speaker whose face looks like that of an exaggerated cartoon character. Instead, your goal is to show a variety of appropriate facial expressions while speaking.

Like vocalics and gestures, facial expression can be used strategically to enhance meaning. A smile or pleasant facial expression is generally appropriate at the beginning of a speech to indicate your wish for a good transaction with your audience. However, you should not smile throughout a speech on drug addiction, poverty, or the oil spill in the Gulf of Mexico. An inappropriate smile creates confusion about your meaning and may make your audience feel uncomfortable. On the other hand, a serious scowl might look hostile or threatening to audience members and become a distraction from the message. If you keep the meaning of your speech foremost in your mind, you will more readily find the balance in facial expression.

Another common problem some new speakers have is showing only one expression. One of our coauthors competed in speech in college. After one of his speeches (about how people die on amusement park rides), one of his judges pulled him aside and informed him that his speech was “creepy.” Apparently, while speaking about death, our coauthor smiled the entire time. The incongruity between the speech on death and dying and the coauthor’s smile just left the judge a little creeped out. If you are excited in a part of your speech, you should show excitement on your face. On the other hand, if you are at a serious part of your speech, your facial expressions should be serious.

Dress

While there are no clear-cut guidelines for how you should dress for every speech you’ll give, dress is still a very important part of how others will perceive you (again, it’s all about the first impression). If you want to be taken seriously, you must present yourself seriously. While we do not advocate dressing up in a suit every time you give a speech, there are definitely times when wearing a suit is appropriate.

One general rule you can use for determining dress is the “step-above rule,” which states that you should dress one step above your audience. If your audience is going to be dressed casually in shorts and jeans, then wear nice casual clothing such as a pair of neatly pressed slacks and a collared shirt or blouse. If, however, your audience is going to be wearing “business casual” attire, then you should probably wear a sport coat, a dress, or a suit. The goal of the step-above rule is to establish yourself as someone to be taken seriously. On the other hand, if you dress two steps above your audience, you may put too much distance between yourself and your audience, coming across as overly formal or even arrogant.

Another general rule for dressing is to avoid distractions in your appearance. Overly tight or revealing garments, over-the-top hairstyles or makeup, jangling jewelry, or a display of tattoos and piercings can serve to draw your audience’s attention away from your speech. Remembering that your message is the most important aspect of your speech, keep that message in mind when you choose your clothing and accessories.

Self-Presentation

When you present your speech, you are also presenting yourself. Self-presentation, sometimes also referred to as poise or stage presence, is determined by how you look, how you stand, how you walk to the lectern, and how you use your voice and gestures. Your self-presentation can either enhance your message or detract from it. Worse, a poor self-presentation can turn a good, well-prepared speech into a forgettable waste of time. You want your self-presentation to support your credibility and improve the likelihood that the audience will listen with interest.

Your personal appearance should reflect the careful preparation of your speech. Your personal appearance is the first thing your audience will see, and from it, they will make inferences about the speech you’re about to present.
