Abstract

Many languages use phonation types for phonemic or allophonic distinctions. This study examines the acoustic structure of the phonetic space for vowel phonations across languages. Our sample of eleven languages includes languages with contrastive modal, breathy, creaky, lax, tense, harsh, and/or pharyngealized phonations, and languages with allophonic nonmodal phonation on particular tones. In compiling and analyzing this sample we address related issues such as contrast vs. allophony, phonetic similarity across languages, and understanding complex contrasts of several multidimensional phonetic categories via data reduction. Based on extensive acoustic analysis, all of the languages' phonations were mapped into a single phonetic space, which exhibits dispersion (languages with more categories use more of the space). The space is largely two-dimensional, with dimensions that can be interpreted phonetically (e.g. dimension 2 is like a traditional breathy-to-creaky continuum) and also can be related back to the acoustic measures that structure them, thus indicating which acoustic measures are most important across languages.
