Abstract
The degree of closeness of the arytenoid cartilages (laryngeal adduction) plays an important role in vocal function and quality. In this paper, adduction for steady vowels was varied between voiced qualities of breathy (greater abduction) to normal to constricted (greater adduction). The superior view of the larynx of various subjects was videotaped and dimensions of laryngeal adduction were measured. The measurements were compared with values of the abduction quotient [1. R. Titze, J. Acoust. Soc. Am. 75, 570–580 (1984)] obtained from simultaneous recordings of the electroglottograph signal and with a measure of electroglottograph waveform width. The width measure strongly correlates with the abduction quotient. Results suggest that the adduction measures may be useful for clinical and research purposes. [Work supported by NIH.]
