Voice Control

Whether the method is old or new, delivering communication in the speaking genre relies not only on words but also on the way those words are delivered. Remember that voice and tone are important in establishing a bond with your audience, helping them feel connected to your message, creating engagement, and facilitating comprehension. Vocal delivery includes these aspects of speech:

• Rate of speech refers to how fast or slow you speak. You must speak slowly enough to be understood but not so slowly that you sound unnatural and bore your audience. In addition, you can vary your rate, speeding up or slowing down to increase tension, emphasize a point, or create a dramatic effect.
• Volume refers to how loudly or softly you speak. As with rate, you do not want to be too loud or too soft. Too soft, and your speech will be difficult or impossible to hear, even with amplification; too loud, and it will be distracting or even painful for the audience. Ideally, you should project your voice, speaking from the diaphragm, according to the size and location of the audience and the acoustics of the room. You can also use volume for effect; you might use a softer voice to describe a tender moment between mother and child or a louder voice to emphatically discuss an injustice.
• Pitch refers to how high or low a speaker’s voice is to listeners. A person’s vocal pitch is unique to that person, and unlike the control a speaker has over rate and volume, some physical limitations exist on the extent to which individuals can vary pitch. Although men generally have lower-pitched voices than women, speakers can vary their pitch for emphasis. For example, you probably raise your pitch naturally at the end of a question. Changing pitch can also communicate enthusiasm or indicate transition or closure.
• Articulation refers to how clearly a person produces sounds. Clarity of voice is important in speech; it determines how well your audience understands what you are saying. Poor articulation can hamper the effect of your script and even cause your audience to feel disconnected from both you and your message. In general, articulation during a presentation before an audience tends to be more pronounced and dramatic than in everyday communication with individuals or small groups. When presenting a script, avoid slurring and mumbling. While these may be acceptable in informal communication, in presented speech they can obscure your message.
• Fluency refers to the flow of speech. Speaking with fluency is similar to reading with fluency. It’s not about how fast you can speak but how fluid and meaningful your speech is. While inserting pauses for dramatic effect is perfectly acceptable, these are noticeably different from awkward pauses that result from forgetting a point, losing your place, or becoming distracted. Practicing your speech can greatly reduce fluency issues. A word on verbal fillers, those pesky words or sounds used to fill a gap or fluency glitch: utterances such as um, ah, and like detract from the fluency of your speech, distract the audience from your point, and can even reduce your credibility. Again, practice can help reduce their occurrence, and self-awareness can help you speak with more fluency.

Gestures and Expressions

Beyond vocal delivery, consider also physical delivery variables such as gestures and facial expressions. While not all speech affords audiences the ability to see the speaker, in-person, online, and other forms of speech do. Gestures and facial expressions can both add to and detract from effective script delivery, as they can help demonstrate emotion and enthusiasm for the topic. Both have the ability to emphasize points, enhance tone, and engage audiences.

Eye contact is another form of nonverbal, physical communication that builds community, communicates comfort, and establishes credibility. Eye contact also can help hold an audience’s attention during a speech. It is advisable to begin your speech by establishing eye contact with the audience. One idea is to memorize your opening and closing statements to allow you to maintain consistent eye contact during these important sections of the script and strengthen your connection with the audience.

Although natural engagement through gestures, facial expressions, and eye contact can help an audience relate to a presenter and even help establish community and trust, these actions also can distract audiences from the content of the script if not used purposefully. In general, as with most delivery elements, variation and a happy medium between “too much” and “too little” are key to an effective presentation. Some presenters naturally have more expressive faces, but all people can learn to control and use facial expressions and gestures consciously to become more effective speakers. Practicing your speech in front of a mirror will allow you to monitor, plan, and practice these aspects of physical delivery.
