Vocal Warm-Ups for Actors: Breathing, Diction and Projection Exercises

Why your voice matters on stage, on camera and in the booth

Every space asks something different of your voice.

On stage

Small theaters often have no mics. Your voice has to reach the last row even when your character speaks quietly. That takes breath and crisp consonants more than raw volume. To test it on a full scene, grab one of these short plays or browse current theater casting calls.

On camera and in the audition room

On camera, it flips. The mic sits close and picks up everything, from a swallowed consonant to a shaky breath. What it needs from you is clarity at low volume, and the same goes for a small audition room. Run your routine before you record a self-tape, and before an in-person read, skim these audition tips.

In the booth and at the podium

In voice acting, your voice is the whole performance. Dubbing also asks you to match the original actor’s lip movements. Our guide on how to become a voice actor covers training and demos. And if you teach, pitch or give talks, the same routine works before you walk into the room.

Vocal warm-ups in 15 minutes

Do this standing, in comfortable clothes, with water nearby. The minutes are a guide, so if one block feels stiff, stay there longer and shorten another. Keep everything at a comfortable volume, away from the very top and bottom of your range. If anything scratches or hurts, stop.

1. Release your neck, shoulders and jaw (2 minutes).
2. Breathe low, into your lower ribs (2 minutes).
3. Hum with your lips closed (2 minutes).
4. Trill your lips and tongue (1 minute).
5. Slide through gentle sirens (2 minutes).
6. Exaggerate your vowels (2 minutes).
7. Run a few tongue twisters (2 minutes).
8. Speak a few lines of text (2 minutes).

Breathing and release warm-ups (minutes 0 to 4)

Start with your body. Roll your head slowly from one shoulder to the other, like a lazy shake of the head. Lift your shoulders toward your ears, hold for two seconds and let them drop. Then massage the hinge of your jaw, just in front of your ears, and let your mouth fall open. For more body work, see our guide to physical acting.

For the breath, rest your hands on your lower ribs, at your sides. Breathe in through your nose and feel your ribs widen while your belly softens. Your shoulders stay still. Let the air out on a long, steady “sss,” like a slow leak in a tire, and count the seconds. Repeat four or five times without squeezing out every last bit of air.

Resonance warm-ups (minutes 4 to 9)

Close your lips, keep your teeth apart and hum on an easy pitch, the “mmm” you make over a great meal. Feel for the buzz on your lips, nose and cheekbones. Then open the hum into vowels, “mmm-ah” and “mmm-ee,” keeping the buzz forward.

Next comes the lip trill, the “brrr” kids make when they play with toy cars. If your lips stall, press a fingertip into each cheek, and try a rolled “r” with your tongue too. Then slide your voice from low to high and back on the trill or on an “oo,” like a distant siren. Start with a narrow range and widen it little by little.

Articulation warm-ups and text (minutes 9 to 15)

Now your mouth gets to work. Say “me, may, ma, mo, moo” with big, exaggerated shapes. Spread a smile for “me,” drop your jaw for “ma” and round your lips for “moo.” Then add consonants and speed with “puh-tuh-kuh” and “buh-duh-guh.” Only go faster when every syllable stays clean, then move on to the tongue twisters.

The last two minutes belong to text, because a warm-up only counts if it reaches the words. Pick a few lines from today’s audition or one of these monologues for auditions. Say them first to someone three feet away, then to someone in the back row, without lifting your shoulders. Whatever changes between the two versions is your homework for the week.

Tongue twisters for actors

Tongue twisters demand precision at speed, which is why actors have used them for generations. These are traditional, so you’ll hear small variations.

• “Red leather, yellow leather.” Repeat it five times without blurring the l and the r.
• “Unique New York.” Said fast, the sounds start to smear, so keep each word distinct.
• “Peter Piper picked a peck of pickled peppers.” Every p wakes up your lips.
• “She sells seashells by the seashore.” Keep the s and the sh apart.
• “The lips, the teeth, the tip of the tongue.” A classic for the front of the mouth.

Go slowly first and overarticulate, almost in slow motion. When a twister comes out clean three times in a row, speed up, and slow down again the moment you trip. Clarity is the goal, because a fast, sloppy twister trains the wrong habit. Record yourself on your phone to catch the syllables you drop. Then play with intention and say it as a secret, a threat or a pickup line.

How to project your voice without yelling

Yelling pushes sound out of your throat. Projection, instead, lets breath and resonance carry your voice across the room.

Pick a spot on the back wall and talk to it as if the person you need to convince were sitting there. Intention organizes the voice better than any note to be “louder.” Take your breath before the line and reach the last word with air to spare, since that’s where many lines die.

Crisp consonants carry meaning, so a clear t, d or p reaches the back row without extra volume. Open your mouth, too, since a clenched jaw shrinks the space the sound comes out of. To practice, count to ten while you back away from a partner. They raise a hand when they stop understanding you, and that’s your working distance.

Where these vocal warm-ups come from

Many of these exercises echo the work of a few influential voice teachers.

Kristin Linklater, who taught voice for years in New York, wrote Freeing the Natural Voice (1976). Her approach frees the voice you already have by releasing habitual tension, rather than adding technique. Cicely Berry became voice director of the Royal Shakespeare Company in 1969. Her Voice and the Actor (1973) pairs breathing and voice exercises with work on poems and dramatic text.

Arthur Lessac first published The Use and Training of the Human Voice in 1960. His training works with what he called consonant, tonal and structural energy, so you feel speech as well as hear it. Patsy Rodenburg, longtime head of voice at London’s Guildhall School of Music and Drama, wrote The Right to Speak (1992). In The Second Circle (2008), she describes three circles of energy. In the first you pull inward, and in the third you push out at everyone. The second is where you give and receive with the person in front of you.

Common vocal warm-up mistakes

The biggest one is warming up only your mouth. Rattling off tongue twisters without releasing your neck or waking up your breath is like stretching your fingers before a run.

Another is pushing from your throat to sound louder or deeper, with your neck tight. If your throat tightens or feels scratchy afterward, bring the volume down and go back to the breath. You don’t need extremes either, so skip the squeaky top notes and the gravelly lows. Finally, avoid the rushed version in the car. A short routine done well beats a long one done halfway.

How to protect your voice

Vocal warm-ups help, but voice care happens all day. The National Institute on Deafness and Other Communication Disorders (NIDCD) estimates that 17.9 million U.S. adults report problems with their voice. Its guide to taking care of your voice lists singers, teachers and public speakers among those who make great demands on their voices.

Its advice is simple. Drink plenty of water, especially when you exercise, and balance coffee or alcohol with extra water. Take “vocal naps,” short stretches of silence during the day. In winter or in a dry climate, run a humidifier (the guide recommends 30 percent humidity). Don’t smoke, and avoid secondhand smoke, which irritates the vocal folds. Cancer of the vocal folds also shows up most often in people who smoke. Spicy food, for its part, can push stomach acid up into your throat.

How you use your voice matters just as much. Get enough rest, because physical fatigue takes a toll on your voice. Avoid the extremes of your range, such as screaming or whispering, and try not to talk over noise. Support your voice with deep breaths instead of relying on your throat alone. In a classroom or a big room, consider a light microphone. And when your voice is hoarse or tired, the guide says to avoid speaking or singing, so skip the warm-up that day.

When to see a doctor

The same guide lists warning signs.

• Your voice has turned hoarse or raspy.
• You can’t hit some high notes you used to.
• Your voice suddenly sounds deeper.
• Your throat often feels raw, achy or strained.
• Talking takes effort.
• You keep clearing your throat.

For timing, the NIDCD page on hoarseness is specific. See your doctor if you’ve been hoarse for more than three weeks, especially if you haven’t had a cold or the flu. Also see a doctor if you cough up blood, have trouble swallowing or breathing, or feel a lump in your neck. The same goes for pain when you speak or swallow, or losing your voice completely for more than a few days. If your voice suddenly disappears while you’re yelling, see a doctor right away, because it can mean a burst blood vessel in a vocal fold.

According to the NIDCD, an otolaryngologist (an ear, nose and throat doctor, or ENT) is the doctor who can best diagnose a voice disorder. Your ENT may refer you to a speech-language pathologist to work on how you use your voice. This guide is training advice and doesn’t replace that visit.

Frequently asked questions

What are vocal warm-ups?

They’re short exercises that prepare your voice before you use it hard. They work on breath, resonance and articulation, so you’re easy to understand without straining your throat.

How long should you warm up your voice?

About 15 minutes covers a full routine like the one above. Short on time? Keep the breathing, a minute of humming and one tongue twister, and finish shortly before you go on.

How can I improve my diction?

Practice daily and listen back. Do the exaggerated vowels and tongue twisters slowly, record yourself and notice which syllables disappear. Reading aloud for a few minutes a day helps too. If you want someone to correct you, take a voice and speech class. Our guide on whether you need acting school can help you weigh your options.

Do vocal warm-ups help with public speaking?

Yes. Teachers, presenters and anyone who speaks in meetings use their voice as a work tool. A five-minute version, with breath, humming and one tongue twister, helps you walk in with your voice awake. If nerves are the bigger problem, read our guide to stage fright.

When should I see a doctor about my voice?

See a doctor if hoarseness lasts more than three weeks, if it hurts to speak or swallow, or if you lose your voice completely for more than a few days. Start with an ENT.
