Analysis of Voice and Hearing (AVAH) Lab

Welcome to AVAH Lab!

The Analysis of Voice and Hearing Laboratory (AVAH Lab) at Michigan State University conducts interdisciplinary research on the biomechanics of voice and hearing. Our work focuses on understanding how vocal anatomy and function give rise to voice production — and how these mechanisms are disrupted in voice disorders, including neurogenic voice disorders.

We use high-speed videoendoscopy and artificial intelligence to develop automated, objective tools for assessing vocal fold dynamics in both healthy and disordered voices. A central thrust of our research is developing voice-based biomarkers of health, including applications in mental health assessment and laryngeal cancer detection.

AVAH Lab also investigates the biomechanics of the auditory system, using mathematical and computational modeling to understand sound transmission through the auditory system to understand voice perception.

By bridging communication sciences and disorders, engineering, and data-driven methods, we aim to advance objective approaches to voice assessment and voice-based evaluation of health conditions.
