Understanding Voice Disorders Through Vocal Fold Movement

Towards Precision Assessment of Dysphonic Speech: From Vocal Fold Physiology to Perception

['FUNDING_R01'] · MICHIGAN STATE UNIVERSITY · NIH-11175409

This project aims to better understand how vocal folds move and how that affects voice quality, especially for people with voice disorders.

What this research studies

We don't fully understand how vocal folds vibrate and how that impacts the sound of your voice, especially when you speak in full sentences. This project wants to find out how vocal fold movements during speech, like starting and stopping sounds, relate to how a voice disorder is perceived. Researchers will use advanced measurements to look at the tiny movements of the vocal folds when people make specific sounds. The goal is to connect these physical movements to how voice quality is heard, both in healthy voices and those with disorders. This work could lead to better ways to diagnose and treat voice problems.

Who could benefit from this research

Good fit: Patients experiencing voice disorders, particularly those with dysphonia, might be ideal candidates for future studies building on this foundational work.

Not a fit: Patients whose conditions are unrelated to vocal fold vibration or voice quality perception would likely not receive direct benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to more precise ways to diagnose voice disorders and develop more effective treatments tailored to individual patients.

How similar studies have performed: While aspects of vocal fold behavior have been studied, this project takes a novel approach by focusing on connected speech and linking precise physiological measures to perceived voice quality.
