VOICE

How to project your voice

AI can write the update you give at the all-hands. Your voice still has to carry it to the back row, and a voice that fades on the way there can sound less sure than you are.

Projecting means your voice carries clearly across a room without shouting or straining, as speech-language pathologist Allison Geller defines it in her guide to vocal projection exercises. Your breath powers the sound and your mouth and face shape it, so your throat can stay relaxed. Most of the drills below follow her published steps, and none of them should hurt.

Why shouting backfires

Forcing volume by shouting squeezes your throat, Geller writes, so your voice tires quickly and can crack. The National Institute on Deafness and Other Communication Disorders (NIDCD), part of the NIH, lists screaming among the extremes to avoid and warns that talking too loudly or too softly can both stress your voice. Trying to talk above noise strains it too.

Geller draws the line this way: projecting means being heard clearly with less effort, while being loud often means forcing more volume from your throat.

Where a bigger voice comes from

Your voice starts as air from your lungs. The Voice Foundation explains that your diaphragm, belly muscles, chest muscles and rib cage work together to move that air up to your vocal folds, and that more airflow makes a louder sound by blowing the folds wider apart as they vibrate. Your throat, mouth and nose then amplify the sound. So the drills below build breath and resonance instead of pushing from your throat.

1. Breathe low

When your breathing is shallow and high in your chest, you run out of air and start to strain, Geller writes. Breathing low, so your belly moves out as you breathe in instead of your shoulders rising, keeps the airflow even. It's what people usually mean by "speak from your diaphragm": Geller calls it diaphragmatic breathing, after the large muscle beneath your lungs.

Drill: put a hand on your stomach and breathe in so your hand moves out. Then breathe out slowly and evenly while you hum or say a sentence.

2. Hold one steady sound

Drill: fill your lungs and hold a single, even "ah", keeping the volume the same from start to finish. As that gets easier, Geller writes that a coach can add gentle swells, louder and then softer on one breath, which build breath control across your range of volume.

3. Find the buzz

Resonance is what lets a voice fill a room without extra effort. As sound leaves your vocal folds, Geller explains, it vibrates through the open spaces in your throat, mouth and face, and those spaces amplify it. Her trick is forward placement: aim the sound toward the front of your face instead of letting it sit back in your throat.

Drill: hum an easy "mmm" and notice the buzz on your lips and the front of your face. Humming through a straw, sometimes called straw phonation, focuses that buzz even more and sends it forward.

4. Warm up with lip trills and sirens

Geller's sample routine uses both as a warm-up.

Drill: relax your lips and blow air through them so they flutter, adding a hum or an easy note as you go. For a siren, glide slowly from your lowest comfortable note up to a higher one and back down on "oo" or a hum.

5. Stand tall

Slouching squeezes your lungs and limits your breath and how much your voice can resonate, so it comes out flat and quiet, Geller writes. Her stance for projecting: feet about shoulder-width apart, shoulders relaxed and down, head level. A FEMA training page on projecting your voice adds that standing up makes it easier to create volume.

Drill: say a sentence hunched over, then stand tall and say it again. Notice how much easier the second one is.

6. Talk to the person farthest away

The FEMA page says to imagine you're talking to the person farthest away, not the front row. George Mason University's Communication Center says to be loud enough that the person farthest back can hear you clearly.

Drill: practice in rooms of different sizes with a friend sitting at the back, as the center suggests, and ask them whether they could hear you all the way through.

7. Keep phrases short and consonants crisp

To be heard, the FEMA page also suggests short phrases and a slower pace. Geller adds tongue twisters for clarity.

Drill: say a tongue twister slowly and cleanly, then a little faster, keeping every sound crisp. Or over-pronounce a sentence, opening your mouth wider and stretching your lips and face more than usual, then say it normally again.

8. Use the microphone

Many speakers refuse a microphone when one is offered, the FEMA page notes, because they think they project well, and too often the audience has trouble hearing them. Its advice is to use one when in doubt, and to hold a handheld microphone about 2 to 10 inches from your mouth, trying a few distances to see what works. NIDCD also suggests a microphone when it fits the setting, such as a classroom or an exercise room.

When noise is the problem, don't try to talk over it or over side conversations, the FEMA page advises.

A few minutes a day

Short, regular practice works better than occasional long sessions, Geller writes, and many people practice for a few minutes most days, warming up before they speak. Her sample routine runs in this order:

A minute or two of breathing.
Lip trills and sirens to warm up.
A tongue twister or two for clarity.
A few sentences spoken from a tall, relaxed posture.

When to stop

Projecting shouldn't cause throat pain or tire your voice. If it does, Geller writes, you're forcing volume instead of supporting it, so stop and check your technique. NIDCD's advice for a healthy voice includes drinking plenty of water, resting your voice through the day and not talking or singing when your voice is hoarse or tired.

A voice that has turned hoarse or raspy, or a throat that often feels raw, achy or strained, can be a sign of a voice problem, NIDCD says. If you think you have one, it advises seeing a doctor to find the cause. The specialist who can best diagnose a voice disorder is an ear, nose and throat doctor, also called an otolaryngologist or ENT.

Practice it in Charisma Lab

Charisma Lab is a speaking coach on your iPhone. Voice Cam, on its home screen, records up to a minute of you talking, with the camera or audio only. Its VOLUME lane traces the last five seconds of your voice as you speak, so you can see whether the ends of your sentences fade.

Train's Grounded Volume, in the Presence track, hands you a line like "I stand by my recommendation." A take passes when you say at least half the line, including its key word, and your last word comes out less than 3 decibels above or below your average volume across the line. It opens once you reach 50% on The Declarative, which is open from the start. Setup is free. If you tap MAYBE LATER when it shows the price, then SKIP FOR NOW when it asks you to sign in, setup goes on to a short live session with the coach. After setup, the app needs Pro, which is $14.99 a month in the US. See pricing.

FAQ

Is projecting your voice the same as talking loudly?

No. Geller describes projection as being heard clearly with less effort, and talking loudly as often forcing more volume from your throat. Projection leans on your breath, your resonance and your posture, so your throat can stay relaxed.

What does "speak from your diaphragm" mean?

Breathe low. Geller describes diaphragmatic breathing as using the large muscle beneath your lungs so your belly moves out when you breathe in, instead of your shoulders rising. Moving air out to speak takes more than the diaphragm, though: The Voice Foundation lists your belly muscles, chest muscles and rib cage working with it.

How do I project my voice in a noisy room?

Don't try to out-shout the noise. NIDCD warns that talking above noise strains your voice and advises avoiding talking in noisy places. If the room is large, or you're not sure people can hear you, the FEMA page says to use a microphone.

How long does it take to project your voice better?

Geller writes that short daily warm-ups often make a noticeable difference within a few days.
