Control of vocal intensity: a comtuter-based system for the assessment and treatment of neurogenic voice disorders

Abstract

This article presents computer-based methods for the assessment and therapy of neurogenic voice disorders. Several tracking and aiming tasks provide objective measures of a dysarthric patient's ability to control the sound pressure level of his/her voice. These tasks can be used in experimental diagnostics aa well as in therapy. Moreover, the system contains options for the assessment of standard diagnostic parameters like maximum phonation time, maximum Ioudnes~, and average loudness of conversational speech.
