Enriching the understanding of glottalic consonant production: Vertical larynx movement in Hausa ejectives and implosives

Abstract

Ejectives and implosives are understood to have laryngeal activity distinct from their pulmonic counterparts. However, while correlations of vertical larynx movement (VLM) with tone and intraoral pressure are known, little articulatory data exists regarding VLM in glottalic consonants. This study examines the degree and timing of VLM in a Hausa speaker’s productions, using real-time MRI of the vocal tract. We use a novel centroid tracking technique developed to quantify VLM. Findings indicate that the onset of VLM is tightly coordinated with oral closure achievement for glottalic stops. For ejectives, larynx raising is faster than in plosives and is especially large for ejective fricatives, which require maintenance of sufficient air flow for turbulence. Additionally, contrary to previous descriptions, implosives and voiced plosives do not differ in degree of larynx lowering. Instead, they contrast in timing of the VLM with the oral …
