This study's objective is to identify the vibratory phase characteristics and corresponding laryngeal configurations of a series of phonation types common in current phonetic usage. The phonation types examined are categorized auditorily following the articulatory framework established by Laver (1968, 1975, 1976, 1980), the general phonetic theory of Abercrombie (1967), and the systematic nomenclature for phonation types provided by Catford (1964). The primary phonation types in this taxonomy are compared laryngographically to determine their larynx waveform characteristics, based on the auditorily controlled performance of a single phonetically trained subject, and are described visually from laryngoscopic observation. This study is intended as a means of establishing a basis for further work in which a larger inventory of speakers of known background and a wider variety of possible phonatory combinations are examined. These preliminary comparisons suggest a set of relationships between phases of the vocal fold vibratory cycle and laryngeal configuration, expressed in terms of contrasting systems of stricture, and support a number of predictions that have been made in the literature on phonatory mechanisms.
