Abstract

The aims of this study were to a) investigate the precise changes in voice during two consecutive reading tasks, b) measure any changes to that same voice after oral hydration interventions following each task, and c) gain insight into the onset and progression of the fatigue as the individual spoke at their normal loudness and pitch throughout the experiment. Within a single experimental session, nine college-aged participants (3 male and 6 female) read aloud (in their normal loudness and pitch) during two 30-minute blocks with hydration and breaks in between. It was hypothesized that acoustic voice measures would decline from the beginning to the end of each reading session, and that drinking water would effect an immediate, transient change in voice that would be masked with continued sustained voice use.
