How to Add Vocal Variety to Your Presentations

Jeffrey Davis • March 10, 2011

Many people ask me how they can add more vocal variety to their business presentations. There are two things to consider when talking about developing vocal range; your long term goals, and your short term goals.

Developing your voice so that it has a lot of flexibility and nuance is best accomplished with a coach over a period of time, however, there are some exercises you can do at home to begin to broaden your vocal range.

The voice begins with the breath. Many of us breathe from the clavicle region (the chest and shoulders). This is not the most efficient way to breath, and does not support vocal production that well. Breathing is an impulse, and when done naturally, the upper chest is relaxed, and the diaphragm is engaged. The diaphragm is the thick muscle under your rib cage:

Ever notice how much vocal power and nuance young children have? That’s because they are breathing naturally from there diaphragm. A relaxed diaphragm creates gentle pressure on the vocal chords thereby producing a grounded sound. If there is little stress in the diaphragm and chords, then it is easier for sound to resonate freely throughout the body, and create vocal variety. But let’s start with breathing… How can you learn (or re-learn) to breath effectively? Try lying on the ground and following these simple steps*:

1) Close your eyes. Begin to notice your breath moving in and out through your mouth. Give yourself this thought “The in-breath is pure relaxation; the out breath will happen naturally if I wait”.

2) At the bottom of your out-breath, wait, but don’t hold your breath, until you feel the need for a new breath.

3) Give in to the need to breathe.

By slowing your breath down, and teaching yourself to give in to the natural reflex of breathing (rather than the manipulated breath), you can learn to engage the diaphragm while you speak, and lower your speaking voice.

Once you have done the breathing exercise for a while, and you have the support of your diaphragm, you can begin to add sound. Add a gentle “huh” sound to the out-breath, making sure not to worry too much about the resulting sound. Notice how the sound feels in your body. Really enjoy the tactile nature of sound. Now expand the sound to a hum, still keeping a nice, relaxed, natural breathing pattern. Notice the sound moving in your chest, and register how it feels.

Next, without losing your breathing, make a higher pitched “hee” sound. Notice the sound moving through your cheeks. Really luxuriate in the sound.

Come to standing. Take out your presentation, and begin the first few sentences. Challenge yourself to keep you breathing relaxed, but also to allow the pitch to fluctuate freely as you speak. See if you notice any differences in your speaking style.

That’s my tip for the day! If you would like to do some private coaching in vocal training, call me at 866.898.7586, and we can set up a free, twenty minute consultation to talk further about your goals.

5 Public Speaking Tips for Non-Native English Speakers Speaking in front of an audience can be challenging in any language. When English is not your first language, you may also be thinking about pronunciation, vocabulary, grammar, and whether your audience understands you. That mental workload can create a common mistake: trying too hard to sound perfect. Effective public speaking is not about eliminating your accent or speaking flawless English. It is about helping people follow your ideas, understand your message, and connect with you. As Stanford communication lecturer Matt Abrahams puts it, “There is no right way to communicate.” Instead of searching for one perfect way to speak, concentrate on making thoughtful choices that help your audience. Here are five practical ways to become a clearer and more confident speaker. 1. Slow down and pause When speakers feel nervous, they often begin speaking faster. Non-native English speakers may also rush because they want to finish a difficult sentence before losing their train of thought. Unfortunately, speaking faster rarely makes you sound more fluent. It may cause words to run together, reduce vocal variety, and make it more difficult for listeners to identify your main point. A short pause gives you time to breathe and organize your next thought. It also gives your audience time to process what you have just said. Research into second-language speech has found that pausing patterns can affect the amount of effort listeners feel they must make to understand a speaker. This does not mean removing every hesitation. It means using intentional pauses at natural moments, such as: Before an important idea After completing a major point Between sections of a presentation Before answering a question Try replacing filler words such as “um,” “you know,” and “actually” with a brief silence. The pause may feel long to you, but it will usually sound calm and deliberate to your audience. Clear beats fast. Give your ideas time to land. 2. Stress your key words English is a stress-based language. In most sentences, some words carry the central meaning while others receive less emphasis. Consider this sentence: “We need to finish the report by Thursday.” The most important words are probably “finish,” “report,” and “Thursday.” Stressing those words helps your audience recognize the message immediately. You can create emphasis by slightly lengthening a word, changing your pitch, increasing your volume, or pausing before it. You do not need to exaggerate. A small vocal change is often enough. Before delivering a presentation, underline one or two important words in each sentence. Practice saying the sentence while allowing those words to stand out. This is especially valuable when presenting numbers, deadlines, recommendations, or contrasts: “Sales increased by fifteen percent.” “We are recommending the second option.” “The deadline is Tuesday, not Thursday.” Your listeners should not have to treat every word as equally important. Vocal emphasis guides them through your message. 3. Use short, simple sentences Complex ideas do not require complicated sentences. Long sentences create more opportunities to lose your place, bury the main point, or confuse the audience. Shorter sentences allow you to express one idea at a time. Communication expert Carmine Gallo calls simplicity a “superpower.” His advice is straightforward: “You have to connect with people in a language they understand.” That does not mean making your ideas simplistic. It means removing language that does not serve your audience. Instead of saying: “Due to the fact that we experienced several unexpected complications during the initial implementation period, we have made the determination that an adjustment to the timeline will be required.” Try: “We encountered several unexpected problems during implementation. As a result, we need to adjust the timeline.” The second version is easier to say, easier to understand, and easier to remember. When preparing a presentation, look for sentences containing several commas, clauses, or abstract expressions. Divide them into two or three smaller thoughts. Simple language does not make you sound less intelligent. It makes your intelligence easier to recognize. 4. Practice aloud Reading your presentation silently is not the same as delivering it. A sentence may look perfectly clear on the page but feel awkward when spoken. Practicing aloud helps you discover difficult words, unnatural transitions, overly long sentences, and places where you need to breathe. Stanford presentation specialist Matt Abrahams emphasizes that preparation and practice are among the most effective ways to feel more confident and deliver an engaging presentation. You do not need to memorize every word. In fact, memorizing an entire presentation can sometimes make a speaker sound rigid or create panic when one word is forgotten. Focus your rehearsal on the parts that matter most: Your first 30 seconds The transition between each major section Important names, numbers, and technical terms Your central recommendation Your final sentence Record yourself on your phone and listen without judging your accent. Ask more useful questions: Can I understand every sentence? Do my key words stand out? Am I pausing between ideas? Does my voice sound engaged? You can also rehearse in small sections. Practice one minute at a time, make one adjustment, and repeat it. Deliberate practice is usually more productive than repeatedly running through the entire presentation.  5. Focus on connection, not perfection An accent is not a communication failure. It reflects your experience, identity, and knowledge of more than one language. Research on second-language speech also distinguishes between accentedness and intelligibility. A speaker can have a noticeable accent and still be understood clearly. Trying to erase every trace of an accent may therefore be a less useful goal than improving clarity, pacing, emphasis, and audience engagement. Your audience is not reading your internal script. They usually do not notice the small grammatical error, missed article, or imperfectly pronounced word that feels enormous to you. They are asking more fundamental questions: Do I understand the speaker’s point? Is this information relevant to me? Do I trust this person? Should I continue listening? One of the world’s most-watched talks on speaking is Julian Treasure’s “How to Speak So That People Want to Listen,” which has accumulated more than 69 million views on TED. His emphasis is not on achieving a perfect accent. It is on speaking with honesty, authenticity, integrity, and care. Your audience wants a human connection, not a flawless performance. Your accent is not the problem You do not need to sound like a native English speaker to become a compelling public speaker. You need a clear message, an audience-focused structure, and delivery choices that make your ideas easier to follow. Slow down. Pause. Stress important words. Simplify your sentences. Practice aloud. Most importantly, focus on the people listening to you. The goal is not to prove that your English is perfect. The goal is to communicate something worth hearing.
