Kurums Speak · №02 · BREATHYour voice runs on air. Learn to take it in quickly and spend it slowly.
Most speaking problems that look like nerves, mumbling or a weak voice start one step earlier, with the breath. This guide shows busy professionals how to breathe for speech in presentations, sales calls and meetings, with three drills you can do at your desk.
In 30 seconds
- Speech breathing is a quick inhale and a long, controlled exhale; at rest you inhale for much longer.
- Breathe low (belly and lower ribs), not high (shoulders and collarbones). The lying-down book drill teaches the feeling in five minutes.
- Plan breath groups: mark a slash where you will breathe, and top up silently at commas and full stops instead of squeezing out the last words.
- For nerves, a slow exhale-focused pattern such as the cyclic sigh has the best early evidence; treat claims about box breathing as promising, not proven.
Key takeaways
- Loudness and steadiness come from steady air pressure below the vocal folds, which the breath supplies; pushing from the throat is the wrong lever.
- Diaphragmatic-abdominal breathing gives the most air for the least tension; clavicular breathing lifts the shoulders and tightens the neck.
- Running out of air is usually a planning problem: sentences too long, no breath points, or speaking on the last dregs of air.
- A long, slow exhale is the most reliable calming tool before you speak, and you can do it unnoticed in a meeting.
- Practice in short daily doses: a timed "sss" and "zzz" exhale tells you within a week whether your control is improving.
Ask a voice coach what to fix first and the answer is almost always the same: breathing. A presenter who rushes, a manager whose sentences fade into a mumble, a salesperson who sounds tight and high on the phone: in many cases the root is a breath that is too high, too small or badly timed.
This is the second guide in Kurums Speak, our series on business speaking and diction. It covers what breath actually does for your voice, how to find the low, diaphragmatic breath, where to breathe inside a sentence, how to stop running out of air, and which calming techniques have real evidence behind them. Everything is designed for professionals speaking business English in meetings, presentations and calls, and every drill fits into a few minutes at a desk.
Why is breath the engine of your voice?
Your voice is made by air. When you speak, your breathing muscles push air up from the lungs, and that air sets the vocal folds in the larynx vibrating. The vocal folds turn a steady stream of air into sound, and your throat, mouth and lips shape that sound into words.
Voice scientists describe the key ingredient as subglottal pressure: the air pressure just below the vocal folds. In plain terms, it is how firmly the air is pressing up from underneath. The National Center for Voice and Speech explains that lung pressure sets this subglottal pressure, and that raising it, all else being equal, increases airflow through the vocal folds and makes the voice louder. There is also a minimum pressure needed just to get the folds vibrating, which voice scientists call the phonation threshold pressure.
That is what singers and voice coaches mean by breath support: keeping the pressure under the voice steady and sufficient, using the muscles of the torso rather than squeezing the throat. When support is missing, people compensate by tightening the neck and larynx to push sound out. The result is a strained, pressed voice, and by late afternoon, a tired one.
Speaking breath is not resting breath
At rest, you breathe in and out in a fairly even rhythm. Speech changes the pattern completely. Researchers at Saarland University and their colleagues note that inhalation takes roughly 40% of a resting breath cycle but only around 10% when speaking, and that in most speaking situations we breathe in every three to four seconds. Speech inhalations are short and fast; the exhale is long, slow and controlled, and it carries the words.
Speaking also makes you breathe more. A study in the Journal of Speech, Language, and Hearing Research found that healthy adults ventilated more during prolonged speaking than in quiet breathing, mainly by taking bigger breaths and breathing more often, and that their breathing took time to settle after they stopped. That is one reason a long presentation can leave you feeling slightly breathless even though you never moved.
Pro tip
If your voice tires by the end of a day of calls, look at breath before you look at your throat. A voice that is "pushed" from the neck tires quickly; a voice carried by steady air from below does not need the push.
Clavicular, thoracic or diaphragmatic: which type of breathing do you use?
Speech-language pathologists often describe three broad patterns, depending on where the movement shows up. Most people use a mix, and the mix shifts under stress. The goal is not to switch off your chest entirely but to let the low, abdominal movement lead.
Quick self-check: sit upright, put one hand on your upper chest and one just above your navel, and breathe normally for five breaths. Then say the sentence "Let me walk you through the numbers" twice. Which hand moves first and most?
| Pattern | What moves | How it sounds at work | Verdict |
|---|---|---|---|
| Clavicular (high, shallow) | Shoulders and collarbones lift; upper chest rises | Breathy starts, short phrases, tight or high-pitched voice, audible gasps | Avoid as your main pattern; it is common under stress |
| Thoracic (mid-chest) | Ribs expand sideways and forward; belly stays fairly still | Adequate for conversation, but phrases may run short in long explanations | Workable; add lower-belly movement for more air |
| Diaphragmatic-abdominal (low) | Belly and lower ribs widen on the inhale; shoulders stay quiet | Longer phrases, steadier volume, more relaxed throat | The target for presenting and long calls |
Patterns as described in speech-therapy practice (e.g. WELL SAID Toronto Speech Therapy; University of Mississippi Medical Center voice handout).
How do you breathe from the diaphragm when speaking?
The diaphragm is a dome-shaped muscle under your lungs. When it contracts it flattens and moves down, which pulls air in and pushes your abdominal contents outward. That is why a good speaking inhale shows up as the belly and lower ribs widening, not as the chest lifting. You cannot feel the diaphragm directly, so you learn it through what moves around it.
The easiest place to find the movement is lying down, because gravity stops the shoulders from helping. The Cleveland Clinic's standard instructions start on your back with knees bent and head supported, one hand on the upper chest and the other just below the rib cage. You breathe in through the nose so the lower hand rises while the chest hand stays still, then let the belly fall as you exhale through pursed lips. They suggest five to ten minutes, three or four times a day, and adding a book on the abdomen to make the muscles work a little harder.
Bringing it up to standing and sitting
Once you can feel the movement lying down, repeat it sitting upright with both feet on the floor, then standing. Keep one hand on your belly. On the inhale, the hand moves out; on the exhale, it moves gently in. Your shoulders should not rise. Then add sound: inhale low, and count from one to five on a single exhale, feeling the belly draw in slowly as you speak.
Do not try to force the belly out or hold it tight. The aim is freedom of movement, not a six-pack. Exaggerated belly pushing creates its own tension.
The book on the belly
5 minPractice drill
- Lie on your back on the floor or a firm bed, knees bent, head on a cushion. Place a medium-weight paperback on your belly, just above the navel. Rest one hand on your upper chest.
- Breathe in slowly through your nose for about three seconds. Watch the book rise while the hand on your chest stays still.
- Breathe out through softly pursed lips for about four seconds and watch the book sink. Do not push it down; let it fall.
- Repeat for ten breaths. If your chest hand moves, slow the inhale down and think of the air filling from the bottom up.
- For the last five breaths, exhale on a quiet "fff" and then count "one, two, three" aloud on the exhale, keeping the book's movement smooth.
- Stand up, put your hand where the book was, and take three breaths that move your hand the same way.
A gradual increase from a 3-second inhale and 4-second exhale towards 5 and 6 seconds follows a progression used in hospital voice handouts. Stop if you feel dizzy.
Where should you breathe in a sentence?
Listeners hear speech in chunks, and the natural chunk is a breath group: the words you say on one exhale. A well-placed breath group matches a unit of meaning, such as a clause, a list item or a number with its context. A badly placed one cuts a phrase in half or forces you to gasp in the middle of an idea.
Breathing in the right places is not just about air. Phonetics research on read and spontaneous English shows that most speech pauses contain an in-breath, and that breath noises tend to mark prosodic and syntactic boundaries; they help signal to listeners that one idea has ended and another is being planned. Your breath, in other words, works as audible punctuation.
Rules of thumb for breath points
- Full stops and paragraph breaks: always a breath point, and a chance for a fuller breath.
- Commas, semicolons, dashes: usually a breath point if the next chunk is long.
- Before key numbers or names: a short breath before "twelve percent" makes the figure land on full air.
- Never between an adjective and its noun, a verb and its object, or inside a number ("four / million").
For any talk that matters, print the script or speaker notes and mark your breath points with a slash. Two to four seconds of speech per breath group is a comfortable target for most people, which lines up with the three-to-four-second breathing rhythm researchers measure in natural speech.
Slash your script
6 minPractice drill
- Take the opening paragraph of your next presentation, or use the practice lines below.
- Read it aloud once without planning and notice where you run short or gasp.
- Mark a slash at every point where you will breathe: full stops always, commas when the next chunk is long, and before key numbers.
- Read again, breathing only at the slashes. Inhale low and quietly; start the next word as soon as the air is in.
- Record the second read and listen. Every phrase should end with the same energy it started with.
Revenue grew twelve percent in Q3 / thanks to two new clients / and lower churn in Europe. //
We have three options. / We can delay the launch, / cut the scope, / or add two engineers. //
I'm calling about your renewal, / which is due on the thirtieth, / and I'd like to walk you through the new pricing. //
One slash is a quick top-up breath; a double slash is a fuller breath at the end of a thought.
Why do you run out of air mid-sentence, and how do you fix it?
Running out of air feels like a lung-capacity problem. It almost never is. Most healthy adults have far more air than any spoken sentence needs. The usual causes are planning and habit.
- Sentences that are too long. Written English tolerates 35-word sentences with nested clauses. Spoken English does not. If you read slide text or a written memo aloud, you will run short.
- Skipping breath points. Nervous speakers often keep talking through natural pauses to avoid silence, then find themselves gasping three clauses later.
- Starting on a high, shallow breath. A clavicular inhale gives less usable air and more tension.
- Leaking air at the start. A breathy first word wastes air before the sentence has begun.
- Squeezing. Speech therapists describe "squeezing" as pushing to the very end of a breath and fitting too many words onto it, often with strain around the voice box.
The fix is to break long sentences into breath groups, breathe at every planned point, and stop each phrase while you still have some air left. Ending a sentence on the last dregs of air is what makes final words drop in volume and pitch, and the end of the sentence is usually where the important word sits.
One breath, running out
So what we're proposing, and this is based on the pilot results from the last two quarters across both regions, is that we move the whole onboarding process to the new platform by March, which would mean...(gasp)
Three breath groups
Here's our proposal. / Based on two quarters of pilot results, / we move all onboarding to the new platform by March.
Common mistakes
- Taking one huge breath before a long sentence. Overfilling creates tension and you still run out; plan more, smaller breaths instead.
- Holding the breath before speaking, which locks the throat and produces a hard, glottal first word.
- Letting the voice fade on the last word of every sentence because the air is gone.
- Reading dense written text aloud without rewriting it for the ear.
How do you take a quick, silent breath between phrases?
Between breath groups you do not need a full breath. You need a top-up: a small, fast, quiet inhale that replaces what the last phrase used. Good presenters take dozens of these and nobody notices.
Phonetics studies give a sense of scale. In an acoustic analysis of read and spontaneous English, in-breath noises mostly lasted between 200 and 600 milliseconds, and professional newsreaders took the shortest breaths. Inhalations become audible during speech in a way they are not at rest, because they are faster and pass through a partly open mouth.
How to make the top-up quiet
- Release, don't suck. At the end of a phrase, simply let the belly relax outward. Air flows in by itself; there is no need to pull it in.
- Open the throat. A noisy gasp usually means a narrowed throat. Think of the beginning of a yawn as you inhale.
- Use the mouth for speed, the nose for longer pauses. Mouth inhalation is the dominant breath during fluent speech because it is faster. When you have a longer pause, such as while a slide changes, a nose breath is quieter and calmer.
- Let the pause do the work. A half-second pause at a comma is natural to the listener. You are not "wasting" time; you are punctuating.
Pro tip
Practice top-ups with a list. Say "Revenue, margin, headcount, churn, pipeline" with a quick silent breath after each word. If you can hear the breath on a recording, slow the inhale slightly and open the throat.
How does posture affect your breathing for speaking?
Your breathing muscles need room to move. Slumping folds the torso over the belly and squeezes the lower ribs; it pushes breathing up into the chest. Rigid "military" posture with a pulled-in stomach does the same thing from the other direction. You want an upright, balanced position that leaves the abdomen and lower ribs free.
Standing
Feet roughly hip-width apart, weight evenly on both feet, knees soft rather than locked. Imagine the crown of your head lifting gently, which lengthens the spine without lifting the chin. Shoulders down and relaxed.
Sitting in meetings and on calls
Sit towards the front half of the chair with both feet on the floor. A voice handout from the University of Mississippi Medical Center recommends roughly 90-degree angles at the ankles, knees and hips when practicing breathing while seated. Avoid leaning back into a soft sofa or crossing your arms tightly over your stomach. If you use a laptop, raise the screen so you are not hunched forward: the head-forward position common on video calls tightens the neck and the muscles around the larynx.
A quick reset before you speak: roll the shoulders up, back and down; let the jaw unclench; take one low breath that moves your belt line; then begin.
In the meeting room · Back-to-back calls
A regional sales manager has six client calls in a row, seated at a laptop on a low table. By the fourth call her voice is thinner and she is clearing her throat. The fix took ten minutes: laptop raised on a stand to eye level, chair moved so both feet are flat, and one belly breath with the shoulders dropped before unmuting for each call. Her throat clearing stopped by the next afternoon, because she was no longer speaking from a hunched, high-chest position.
Can breathing techniques calm presentation nerves?
Yes, with honest caveats. Breathing is one of the few parts of the stress response you can control directly, and slowing it down, especially lengthening the exhale, is a well-established way to take the edge off physical arousal. What is less established is the claim that one specific technique is dramatically better than the others.
The cyclic sigh ("physiological sigh")
The best-known recent study is a 2023 randomized trial in Cell Reports Medicine by Balban and colleagues at Stanford. 108 participants practiced for five minutes a day for 28 days: cyclic sighing, box breathing, cyclic hyperventilation with retention, or mindfulness meditation. All groups reduced anxiety and negative mood. Breathwork overall increased positive mood more than mindfulness, and cyclic sighing, an inhale, a second short "top-up" inhale, then a long, slow exhale, produced the largest improvement and the largest drop in resting respiratory rate. The authors flag real limits: the study was exploratory and registered after the fact, it was run remotely, it lasted only four weeks, and participants were mostly university students.
Box breathing
Box breathing uses four equal counts: inhale, hold, exhale, hold. It is popular in the military and police, but popularity is not evidence. A 2026 study in Comprehensive Psychoneuroendocrinology, as reported by PsyPost, found that five minutes of either box breathing or prolonged exhalation before a stressful speaking task kept heart rate, anxiety and a salivary stress marker from rising, compared with normal breathing. The sample was small (66 students), and box breathing was not clearly better than simply exhaling slowly.
The bigger picture
A 2023 meta-analysis in Scientific Reports (Fincham and colleagues) pooled 12 randomized trials with 785 adults and found breathwork produced a small-to-medium reduction in self-reported stress compared with controls. The authors warn against overstating the evidence: most trials had some risk of bias and all outcomes were self-reported. Breathing helps; it is not a cure for severe anxiety.
| Technique | How to do it | Where it fits | Evidence strength |
|---|---|---|---|
| Cyclic sigh | Inhale through the nose, add a short second inhale to top up, then a long, slow exhale through the mouth. 1 to 5 minutes. | Corridor or bathroom before a pitch; first minutes after a tense meeting | One 2023 RCT; promising, not definitive |
| Long-exhale breathing | Inhale for about 3 to 4 seconds, exhale for 6. Can be done silently through the nose. | In your seat while someone else is speaking | Supported by the 2026 speaking-task study and broader breathwork trials |
| Box breathing | Inhale 4, hold 4, exhale 4, hold 4. Shorten counts if the holds feel strained. | Before you walk into the room | Small studies; not clearly superior to a slow exhale |
| One low breath before speaking | A single belly breath with shoulders relaxed, released into your first word | Every time you start to speak | Practical voice technique rather than a stress intervention |
Educational summary. If anxiety about speaking is severe or affects your work, speak to a doctor or a qualified therapist.
In the meeting room · Ten minutes before the board
A finance director is due to present a budget overrun. Waiting outside the boardroom, his heart is pounding. Instead of rereading slides, he does two minutes of cyclic sighs in a quiet corridor, then walks in and, while being introduced, takes two slow exhales through the nose that nobody can see. His opening sentence has been marked with breath points and rehearsed. He starts on a low, full breath and the first sentence lands steady, which settles the rest of the talk.
How do you build breath control with the sss and zzz drill?
Breath control for speaking is the ability to release air slowly and evenly. The classic way to train and measure it is a sustained sound. A hissed "sss" uses air only, with no voice; a buzzed "zzz" uses the same mouth position but adds vibration from the vocal folds. Voice clinicians use these sounds because they are easy to time and compare.
Some reference points: the Sydney Voice Lab's normative sheet notes that adults can typically hold a quiet sound for about 15 to 20 seconds, and that the ratio of "s" time to "z" time in adults typically falls between about 0.99 and 1.40. In plain terms, most people can hold the two sounds for about the same time. If your "zzz" is much shorter than your "sss", air may be escaping through the vocal folds while you voice. That is not a diagnosis; it is a reason to ask a speech-language pathologist if you also have hoarseness.
Your goal is not to set records. A smooth, even 15-second "zzz" is far more useful in a meeting room than a strained 40-second one. Keep the shoulders still and the sound steady in volume from start to finish.
| Week | Target (steady, not strained) | Speaking add-on |
|---|---|---|
| 1 | Find your baseline; record 3 rounds of "sss" and "zzz" | Count to 10 on one breath |
| 2 | Baseline + 3 seconds, same volume start to finish | Read a 2-line slash-marked passage |
| 3 | Baseline + 6 seconds, or about 15 s if you started low | Read a full paragraph with planned breath points |
| 4 | Hold 15 to 20 s evenly on both sounds | Deliver a 1-minute talk and record it; check that sentence endings stay strong |
A suggested four-week progression for professionals. The 15–20 s reference comes from Sydney Voice Lab normative data (Goy et al., 2013).
The sss–zzz ladder
4 minPractice drill
- Sit or stand tall. Take one low, quiet breath through the nose, belly moving out.
- Hiss on a steady "sss" at a comfortable volume. Start a phone stopwatch as you begin and stop it when the sound wobbles or fades. Write down the time.
- Rest for two normal breaths. Repeat on "zzz", feeling a gentle buzz on the tongue and teeth. Write down the time.
- Do three rounds of each and keep your best even (not strained) times.
- Finish by speaking a 15-second sentence on one breath, keeping it as smooth as your best "zzz".
Stop if you feel light-headed. Steadiness matters more than length.
How should you breathe in meetings and on video calls?
Meetings bring a different problem from presentations: you have to speak at short notice, often after sitting still and silent for a while. Breathing during long silent listening tends to become shallow, so your first sentence starts on almost no air. The fix is simple: when you feel you are about to speak, take one low breath while the other person finishes, and start your first word on the exhale. That single breath also gives you a natural half-second to organize the opening of your point.
Microphones and breath noise
On calls, headsets and laptop microphones pick up sounds a room would hide. Breath noises during speech are soft, roughly 16 to 29 decibels below the surrounding speech in one acoustic analysis, but a microphone a few centimeters from your mouth brings them forward. To keep them out of your listener's ear:
- Position the microphone slightly to the side of your mouth, not directly in front, so the airflow from your exhale and inhale does not hit it.
- Use the nose for between-sentence breaths when the pace allows; nose breaths are quieter than mouth gasps.
- Avoid sighing into the mic. A long exhale before you speak reads as boredom or irritation on a call, even when you meant it as a calming breath. Do your calming breaths muted.
- Keep water nearby. A dry mouth produces clicks and makes you breathe through the mouth more. Sip water between speaking turns.
When you are leading a call, the same breath-group planning applies to your opening and to any update you give. A status update spoken as three short breath groups is easier to follow over compressed audio than one long run-on sentence.
In the meeting room · The weekly team call
A project lead notices that her updates sound rushed on the recording, with a loud gasp in the middle of each. She moves her headset microphone to the side of her cheek, mutes for two slow exhales before her turn, and splits her update into three marked breath groups: status, risk, ask. The gasp disappears from the recording, and her team stops asking her to repeat the risk item.
Pro tip
On important calls, keep a sticky note with your opening sentence written out and slash-marked. Read the first line from it if you need to. The rest flows more easily once the first breath group lands.
When is breathlessness while speaking a sign to see a specialist?
Breath training is safe for most people, but it is educational, not treatment. Some signs suggest something other than technique is involved, and they deserve a professional opinion.
- Hoarseness that lasts. The American Academy of Otolaryngology clinical practice guideline recommends laryngoscopy (an examination of the larynx) if a voice problem does not resolve within four weeks, or sooner if a serious cause is suspected.
- Breathlessness out of proportion to effort, chest pain, wheezing or breathlessness at rest. These are reasons to see a doctor, not to do more breathing exercises.
- A voice that tires within minutes, pain when speaking, or a persistent lump-in-the-throat feeling.
- Dizziness or tingling during breathing exercises. Stop, breathe normally, and keep sessions gentle. Rapid or forced breathing patterns are not appropriate for everyone.
A speech-language pathologist who specializes in voice can assess your breathing pattern, voice quality and speaking habits, and an ENT (otolaryngologist) can examine the vocal folds. If you rely on your voice for work, a single assessment can save months of trial and error.
Safety notes
- Do breathing drills seated or lying down at first; never while driving.
- Skip breath-holding patterns such as box breathing holds if you are pregnant or have a heart or lung condition, unless your doctor agrees.
- Do not use breathing exercises to push through pain or a lost voice; rest the voice and get it checked.
Frequently asked questions
What is the best breathing technique for public speaking?
For voice, low diaphragmatic-abdominal breathing combined with planned breath points in your script. For nerves before you speak, a slow exhale-focused pattern such as the cyclic sigh has the most promising early evidence. Use both: one prepares the voice, the other settles the body.
Should I breathe through my nose or my mouth when speaking?
Both. During fluent speech most quick top-up breaths go through the mouth because they are faster. Use the nose for longer pauses and for calming breaths before you speak, because nose breathing is quieter and tends to be slower.
How long does it take to improve breath control for speaking?
Many people notice a difference in steadiness within a week or two of daily five-minute practice, especially once they start marking breath points. Building it into habit under pressure takes longer, which is why rehearsing real presentation openings matters more than drill records.
Why do I gasp for air when I present but not in conversation?
Stress pushes breathing high into the chest and makes many people talk through natural pauses. Presentations also tempt you into long, written-style sentences. Shorter sentences, slash-marked breath points and one low breath before your opening line usually solve it.
