One difficulty in the physical observation of articulatory structures in the pharynx is the reliability of measurements for comparative purposes. The objective of the present approach is to review and explore techniques of identifying and measuring degrees of adjustment of the pharyngeal articulatory mechanism in the production of auditorily controlled settings. Anatomical landmarks are identified on computer images transferred from laryngoscopic videotapes, and measurements are taken of dimensions defined by the configuration of the pharyngeal articulators. Comparisons are taken across linguistically contrastive consonants and vowels, where the activity of the laryngeal sphincter accompanies tongue retraction and larynx raising, and implications are drawn for the measurement of voice quality settings. Measurements of the "tense," raised-larynx series of Yi (Nosu) are illustrated.
