The effect of sustained phonation at high and low pitch on vocal jitter and shimmer.
Looking for possible signs of vocal fatigue, acoustic waveform perturbation was measured in normal female subjects during sustained phonation at various fundamental frequencies (Fo). At none of the pitch levels a rise of the jitter or the shimmer was found after 25 min of vocalization. On the other hand, an effect of Fo was seen from the start: above the habitual speaking Fo of our subjects' voices there was a tendency for the jitter to be higher and for the shimmer to be lower.
