Characterization of upper esophageal sphincter pressures relative to vocal acoustics

This is the authors' abstract. We don't add key points for this paper.

We identified relationships between upper esophageal sphincter (UES) pressures and vocal acoustics during phonation in vocally healthy individuals, potentially reflecting the influence of strength of vocal fold adduction and other phonatory factors on vocal acoustics. This methodology could lead to the development of a clinical and research tool that could provide insight into the strength of vocal fold adduction, a critical factor influencing voice quality that has historically been difficult to assess.
