Vocal fold vibration patterns and modes of phonation

Journal/Book: Folia Phoniatr Logop. 1995; 47: 218-28 1021-7762.

Abstract: Voice source characteristics of some different modes of phonation as produced by a trained voice are combined with an analysis of the same singer's vocal fold vibrations as recorded by a digital high-speed imaging technique. Considerable differences between modes are found with regard to the waveform and amplitude of vocal fold vibration. The results support the assumption that the physiological input parameter underlying differences in mode of phonation is glottal adduction.
