Abstract
Voice quality is known to fluctuate in adults over relatively short periods of time. Quantifying the degree to which the normal and pathologic voice fluctuates can be applied in various ways for clinical evaluation and treatment purposes. Quantifying true fluctuations in voice quality depends on the reliability of the specific acoustic measure being used. Some acoustic measures may be more reliable than others in tracking these fluctuations. This article reviews the literature to date regarding voice quality fluctuations in adults over short periods of time (i.e., days and weeks). Recommendations for future research directions are also given.
