The laryngeal articulator's influence on voice quality and vowel quality

Monday 24 April 2017, 3.00PM to 4.30pm

Speaker: Dr. John Esling, Professor Emeritus at the University of Victoria

The movements of the laryngeal articulator are described with images from experimental phonetic studies of pharyngeals, glottal and epiglottal closure manoeuvres, multi-level laryngeal vibrations, and tonal register qualities originating from different postural settings of the vocal folds, ventricular folds, epilaryngeal tube, aryepiglottic folds, laryngeal cartilages, base of the tongue, and the pharyngeal airway. Laryngoscopic, cineradiographic, ultrasound, and magnetic resonance imaging illustrate the behaviour of the laryngeal constrictor mechanism performing various articulations. Lingual-laryngeal interactions form an important part of Esling's (2005) Laryngeal Articulator Model, which reshapes vowel space organization to reflect the laryngeal component of vowel articulation. Vowel quality is shown to interact with larynx state and with larynx height. We will examine the instrumental evidence to identify the nature of the articulatory changes involved when a series of laryngeal states are combined with vowel targets. Laryngeal conditions examined together with peripheral vowel production include: glottal stop, epiglottal stop, creaky voice, and raised larynx voice (pharyngealization). Findings indicate that a vowel cannot be identified solely on the basis of oral parameters and that vowels differ in the way they respond to particular laryngeal settings.
