Results In 60 patients with organic diseases of vocal cords, all the acoustic parameters were significantly increased and the spectrograph showed irregularity,breakage or lack of harmonic waves and formants, and increase of noise. In 50 cases with functional voice disorder, the shimmer and NNE were significantly increased but the jitter was usually normal. The spectrograph showed pathologic changes of harmonic waves and formants in middle and high frequencies.
