Recently, NIH based programs such as a Bridge to Artificial Intelligence (Bridge2AI) have highlighted the use of artificial intelligence to identify acoustic biomarkers of disease. Therefore, the investigators hypothesize that progression of LTS scar can be quantified using acoustic measurements and machine learning. The goal of this clinical trial is to remotely monitor patient voice quality in an effort to determine if regularly performed voice recordings can be used as a diagnostic tool in order to predict the need for dilation procedures. The investigators feel that successful use of remote voice recording technology with algorithmic analysis will improve patient quality of life.",[85],"Idiopathic Subglottic Tracheal Stenosis",[87,88],"Tracheal Stenosis","Voice Quality","NOT_YET_RECRUITING","2025-08-01",{"date":92,"type":93},"2025-08-06","ACTUAL",{"date":95,"type":81},"2026-07-01",{"date":97,"type":81},"2028-12-01",{"name":5,"class":6},1]
