Vocal warm-ups: a 5-minute routine before you speak or sing

Five minutes of the right exercises makes your first sentence sound like your best voice instead of your just-woke-up voice. Here is the routine, a 2-minute emergency version, and what singers should add.

Why warm up your voice before speaking?

A vocal warm-up coordinates breath, vocal folds and articulators before you need them. Without one, your first minutes of talking often sound croaky, breathy or tight, because the muscles of the throat, jaw and tongue are still cold and the breath is shallow. With one, you start in the voice you normally reach after twenty minutes of conversation.

The research on warm-ups for speakers is thinner than for singers, but one part is well grounded. Exercises that partly close the mouth, like humming, lip trills and phonating through a straw, are called semi-occluded vocal tract exercises. Voice scientist Ingo Titze's analysis showed why they help: the partial closure raises air pressure above the vocal folds, which lets the voice run more efficiently and with less forceful collision of the folds (Titze, 2006, Journal of Speech, Language, and Hearing Research). That is why every good routine below leans on them.

A warm-up also helps with nerves. Slow breathing and familiar sounds give your body something to do besides worry. If anxiety is the bigger problem, see our guide to overcoming the fear of public speaking.

The 5-minute vocal warm-up routine

Do these six steps in order, at a comfortable, moderate volume. The table is the quick reference; details for each step follow.

1. Body (45 seconds)

1. Roll your shoulders back five times, then let them drop.
2. Tilt one ear toward the shoulder for 10 seconds, then the other.
3. Put your fingertips on the jaw hinge just in front of your ears, let the jaw hang open and massage gently for 10 seconds.
4. Take a real yawn and sigh out on a relaxed "haaa," sliding from a middle pitch down to a low one. Twice.

2. Breath (45 seconds)

Put a hand on your belly. Breathe in through your nose for four counts so the hand moves out, then hiss "sss" for eight counts or more, keeping the hiss perfectly even. Do three rounds. You are setting up the low, steady airflow everything else runs on.

3. Straw, lip trills and humming (1 minute)

• Straw phonation (20 seconds). Hum a comfortable note through an ordinary drinking straw, then slide it up and down. Your cheeks stay flat and the sound feels almost effortless.
• Lip trills (20 seconds). Blow through loosely closed lips so they flutter like a motorboat, adding voice and gliding through a few notes. If your lips will not trill, press the corners of your mouth lightly with your fingertips.
• Humming (20 seconds). Hum "mmm" with lips closed and teeth apart until you feel a buzz on your lips, then open into "mmm-ah, mmm-oh, mmm-ee."

4. Sirens (45 seconds)

Glide on "ng" (the end of "sing") or on "oo" from the bottom of your comfortable range to the top and back, like a slow siren. Do five, keeping the volume light. You should feel no squeeze or crack at the top; if you do, stop lower. Speakers only need the middle of the range; singers can go wider.

5. Articulation (1 minute)

Say "puh-tuh-kuh" ten times, then "buh-duh-guh" ten times, starting slowly and speeding up while every sound stays crisp. Finish with two tongue twisters, slow then faster. "Red leather, yellow leather" and "The tip of the tongue, the teeth, the lips" are good defaults; there are 60 more, sorted by sound, in our list of tongue twisters for diction.

6. Speech run-through (45 seconds)

Say the first two or three sentences you will actually use, out loud, at the volume the situation needs. For a room, aim at the back wall without pushing from the throat; the technique is in how to project your voice.

The 2-minute emergency warm-up

When you have two minutes before a call, interview or toast, keep the steps that do the most work: release, breath, a semi-occluded exercise and your first line. Everything here can be done quietly.

1. Release (15 seconds). Drop the shoulders, let the jaw hang and move it gently side to side.
2. Breathe (20 seconds). Two slow breaths, in through the nose, out through the mouth on a long, even exhale.
3. Hum or trill (40 seconds). Three slow slides from low to high and back on a hum, a lip trill or through a straw. Humming with closed lips is close to silent in an open office.
4. One twister (15 seconds). "Red leather, yellow leather," three times, slow then faster.
5. First line (30 seconds). Say your opening sentence out loud twice at the pace and volume you will use.

Vocal warm-ups for singers

Singers need everything above plus range, agility and dynamic control. Add five to ten minutes after the sirens, always starting in the middle of your range and moving outward rather than opening with your highest notes.

1. Five-note scales on a lip trill or straw (2 minutes). "Do-re-mi-fa-sol-fa-mi-re-do," moving up a semitone each time, then back down.
2. Hum into vowels (1 minute). Hum a note, then open to "ah" without losing the buzz: "mmm-ah." Repeat on several pitches.
3. Arpeggios on "mee-may-mah-moh-moo" (2 minutes). Keep the tone even as the vowels change.
4. Light staccato (1 minute). Short, bouncy "ha-ha-ha" on a 1-3-5 pattern for clean onsets and breath support.
5. Swell on one note (1 minute). On a comfortable pitch, go soft, a little louder, then soft again over eight counts without the pitch drifting.
6. Half-voice run (2 minutes). Sing a phrase from your actual song at half volume before singing it full out.

What to avoid before you speak or sing

Avoid anything that dries, irritates or overloads the vocal folds right before you need them. The National Institute on Deafness and Other Communication Disorders recommends staying well hydrated, resting your voice and avoiding the extremes of your range such as screaming or whispering (NIDCD).

• Throat clearing. Each forceful clear bangs the vocal folds together, and the habit feeds itself. Swallow, sip water or hum gently instead. The NIDCD lists frequent throat clearing as one of the signs of a voice problem.
• Whispering to "save" your voice. Whispering is not the rest it feels like, and it is one of the extremes the NIDCD advises against. If you need vocal rest, be quiet.
• Shouting or warming up loud. A warm-up is easy and moderate. Belting or yelling first thing tires the voice before you start.
• Starting with your extremes. Begin in the middle of your range and expand. Going straight for your highest or lowest notes is how voices crack.
• Dry air and dehydration. Drink water through the day, not just a gulp before you start, and balance caffeine or alcohol with extra water.

The dairy question, honestly. The idea that milk creates mucus is mostly a myth. A review of the evidence concluded that milk does not increase mucus production, and in one line of studies people reported the same thick-throat feeling after a soy drink with a similar texture (Wüthrich et al., 2005, Journal of the American College of Nutrition). The coating sensation is real for some people, though. If you feel it, skip dairy for an hour or two before you perform; otherwise there is nothing to worry about.

How to know your warm-up is working

Your voice should feel easier after the warm-up than before it, never tired. The simplest test is to record the same two sentences before and after and compare: a warmed-up voice usually sounds steadier, more resonant and less creaky on the first words.

Voceris measures stability, resonance and vocal fry on each recording, which makes that before-and-after comparison concrete rather than a feeling.

A warm-up prepares your voice for today; it does not train it for the long term. For drills that build breath support, resonance and range over weeks, see our voice exercises for speaking.

When to see a professional

A warm-up should never hurt. If it feels harder over time, if your voice tires after a short talk, or if you have pain, a lost range or hoarseness lasting more than two or three weeks, see a doctor or an ear, nose and throat specialist. A speech-language pathologist can then help you use your voice in a healthier way.
