SOME PHYSIOLOGICAL PARAMETERS FOR PROSODIC DESCRIPTION,
Abstract
The objective of the study is to investigate the physiological parameters of voice production in regard to the problem of the description of the prosodic aspect of spoken language. The parameters considered include the length, thickness, and medial compression of the true vocal folds, the tension of the vocalis muscle, the resistance of the glottis to the flow of air, the subglottic pressure, the volume velocity of glottal airflow, and the motions of the laryngeal cartilages. In a study of the mechanics of the laryngeal cartilage system, the degrees of freedom of the cartilage motions are isolated and employed to describe the motions mathematically. It is shown how four quantities which are measurable in a laryngoscopic view depend on the degrees of freedom. The resulting equations are solved to show that it should be possible to evaluate the degrees of freedom from the laryngoscopically measurable dimensions. The relations between the degrees of freedom and changes in the lengths of the intrinsic laryngeal muscles are outlined. An experimental study was conducted to investigate the behavior of some of the physiological parameters of voice production during prosodic variations in the voice. (Author)
