Stroboscopy for Computer Based Voice Analysis

We have developed a prototype voice analysis station which integrates a number of minimally invasivfor visualizing and quantifying those aspects of voice quality which are related to the functioningsource. As presently configured, this voice analysis station develops a unified- computer-based recowaveforms related to glottal airflow, subglottal air pressure, radiated acoustic pressure (microphonarea (EGG). This project has the goal of developing a new system of digital stroboscopy which couldvideo images of laryngeal vocal fold vibration that could be readily integrated into a computer- basand which offer several advantages not attainable with standard laryngostroboscopy. A prototype digibe developed and tested in Phase I. A practical version suitable for clinical use would be developedintegrated into a voice analysis station. Suggested voice testing protocols would also be developedtested.
