Precision view of how your voice works and sounds when speaking
Official title: Towards Precision Assessment of Dysphonic Speech: From Vocal Fold Physiology to Perception
Funded at Michigan State University · NIH-11379998 · Data updated 2026-11-12
A research project at Michigan State University will study how vocal folds move and how voice sounds are perceived during everyday speech, with the goal of improving diagnosis and treatment of voice disorders.

Who could benefit from this research
✓Could help
Individuals with voice disorders or perceptual voice concerns who can participate in speech tasks and voice measurements.
✕Less likely to help
People without voice concerns or those unable to participate in speech tasks may not directly benefit.
What this research studies
Researchers will measure detailed vocal fold activity and how it shapes voice quality during connected speech, using automated methods to capture onset, offset, and timing of vocal vibration in simple vowel-consonant-vowel sequences. They will connect these physiological measurements to how listeners perceive voice quality, aiming to create better diagnostic tools and targeted treatment options. The work brings together experts from several fields to build a framework that links vocal physiology and perception in realistic speech. The project emphasizes analyzing co-articulation effects and how phonatory changes relate to functional voice impairment.
Why it matters
Potential benefit: If successful, this work could lead to more precise diagnosis and personalized therapies for people with voice disorders.
How similar studies have gone: Similar approaches have shown promise in linking physiology and perception, but this project advances with automated measures and connected-speech contexts.
