Abstract
In the setting of a voice clinic, the voice may be assessed in a number of different ways. As a bare minimum, assessment should include stroboscopic examination, patient self-reported questionnaires, and clinician-reported perceptual evaluation. In addition, recordings of the voice may be analyzed using computer software: several different measures exist, but the most widely used are jitter, shimmer, and noise-to-harmonic ratio. There are, however, significant limitations of these measures, including access to the equipment, inter-test reliability of the measurements, and a lack of correlation with clinical improvement. Other mathematical techniques (nonlinear algorithms) may provide more robust measurements. A pragmatic approach to assessment in the voice clinic suggests that stroboscopic examination should be accompanied by patient-reported questionnaires and clinician-rated voice assessments.
