Squeeze

The glottis closes too tightly; the air gets stuck and the voice sounds squeezed and effortful.

In One Sentence

Glottal closure is too tight — the airflow gets pinched, and the voice sounds squeezed, tight, and effortful.

How to Read It

Watch the Airflow Balance (NAQ) chart. If the needle keeps sitting in the lower red "squeeze zone" (NAQ < 0.1), the glottis is pressed too tightly.

Note (register gating): when the student profile has the second passaggio filled in, this symptom is no longer judged above it (the third passaggio cannot physically squeeze — Justin 2026).

Why Does This Happen?

CauseDescription
Extrinsic compensationThe folds can't close enough on their own, so the larynx "helps" by squeezing
Over-strong contractionThe two folds press together hard and pinch the airflow
Breath-holding habitSealing the glottis before onset, then forcing air through

How to Improve

  • Sigh on "hah——": release the closure first and feel the air flow freely
  • Lip bubbles: "brrr" to balance air and closure
  • Straw phonation: lowers subglottal pressure and prevents breath-holding
