Modeling and imaging of the vocal fold vibration for voice health

Modeling and imaging of the vocal fold vibration for voice health 

It is common to detect voice problems when repetitive high voice loads occur, since vocal folds experience damage at high cumulative loads. The degradation that affects the vibrations of the vocal folds can be identified by means of a high-speed camera; overloading of the vocal tract leads to abrasion of the tissue, and consequently, to superficial changes and modification of the normal oscillatory pattern.

In this project biomechanical models of pathological vocal vibrations, including models of degradation and recovery of tissues, are investigated. High-speed movies of unhealthy larynges are intended to be used as a research tool to improve the existing models for irregular or disordered voice and analyze the sensitivity of the model to the input parameters.

The project is expected to generate objective clinical methods to analyze high-speed movies of vocal vibrations, in order to identify subjects with functional voice problems.
