Acoustic analysis of voice, speech, and breath sounds in subglottic stenosis
Status: Recruiting
This study is about understanding how subglottic stenosis (narrowing within the airway) affects voice, speech, and breathing sounds. Changes in airflow from airway narrowing can alter how the voice sounds, how speech is timed, and how breaths are taken during speaking. By using advanced, noninvasive sound analysis, we hope to identify patterns that may help detect airway narrowing earlier and track improvement after treatment.
