University of Wisconsin, Madison
365 participants

INTERVENTIONAL
Conditions
Summary
The goal of this clinical trial is to create a vocal health database of people aged 4-65 with no diagnosed voice pathology. The main question it aims to answer is: * what is the best way to assess pediatric voices; and, * what are the differences between healthy and dysphonic pediatric voices? Participants will complete one 60 minute session involving one of three types of aerodynamic interruption.

Interventions
Participants will produce a sustained vowel into a mouthpiece (with nose-clip) connected to a PVC tube, with a balloon valve
Incomplete airflow interruption uses a Y-shaped device. The participant produces a sustained /a/ into a mouthpiece and air filter connected to the tube. The tube splits into two tubes distally.
Participant phonates through a mouthpiece into a PVC tube that splits into two paths. One path is connected to an open balloon valve. When the balloon is inflated and blocks the path, air is redirected into the other path which is gated by a one-way valve.
