Checking action allows you to ____

• A. maintain constant airflow and pressure during speech by engaging inspiratory muscles
• B. talk louder
• C. talk with the lowest subglottic pressure possible
• D. maintain constant airflow and pressure during speech by engaging expiratory muscles

Answer: (A)

Checking action is using the inspiratory muscles to restrain and regulate exhalation so that the amount of air leaving the lungs stays steady. This keeps both the airflow and the subglottal pressure relatively constant during speech, which helps phonation stay smooth and controlled. That’s why describing it as maintaining constant airflow and pressure during speech by engaging inspiratory muscles fits best. Using expiratory muscles would push air out more forcefully and disrupt the steady flow, and aiming for the lowest possible subglottic pressure isn’t the goal when you’re trying to keep airflow steady.
