Dynamic vibratory patterns of normal adults during steady phonation obtained with high-speed digital kymography (DKG) are presented. Steady phonation consists of quasiperiodic harmonics configured in a tilted shape with robust peaks and no spectral smearing. A range of asymmetry between the left and right vocal folds (VF) vibration is also seen in normal voices.
