Voice projection exercises

By the SLT info editorial team · Last updated 2026-10-24

Projection is not shouting. It is making your voice carry efficiently, with good breath support, open resonance and clear articulation, so you can be heard without strain.

What projection really is

Shouting pushes more pressure through a tight throat. Projection gets more sound for less effort: the breath is steady, the throat stays open, the sound is shaped in the mouth, and the words are crisp. That is why a trained teacher or actor can fill a room all day without losing their voice.

1. Set up your posture

2. Build breath support

Good support means a low, relaxed breath and a steady release, not a big, tense gulp.

  1. Rest a hand on your lower ribs and belly. Breathe in quietly through the nose or mouth and feel the lower ribs and belly widen.
  2. Release the air slowly on a gentle “sss” for as long as you can keep it even. Aim for a steady ten seconds and build gradually.
  3. Repeat with “zzz” so the voice is switched on.

3. A five-minute warm-up

ExerciseHowTime
Gentle hummingHum “mm” on a comfortable pitch; feel a buzz at the lips.30 s
Lip trillsBlow air through loose lips so they flutter; slide up and down in pitch.1 min
Straw phonationVoice gently through a narrow straw (a coffee stirrer or drinking straw); glide up and down.1 min
Sirens on “ng”Glide from low to high and back on “ng” as in “sing”, keeping effort light.1 min
ArticulationSay “red leather, yellow leather” or “unique New York” slowly, then faster, with clear consonants.1 min
Read aloudRead a paragraph at your intended speaking volume, then one notch louder.30 s

Exercises that partly close the vocal tract, such as straw phonation, lip trills and humming, are widely used because they make the voice easier to produce while keeping the throat comfortable (Titze, 2006). Stop if anything hurts.

4. Shape the sound

5. Protect your voice

When to get help. If your voice is hoarse for more than about four weeks, hurts to use, tires quickly or keeps losing its range, see your doctor. A speech and language therapist with voice training can build a programme for you.
