There are no back vowels: The laryngeal articulator model

As an alternative to the high-low-front-back model of vowel specification, the laryngeal articulator model is proposed, based on a reinterpretation of how the vocal tract functions to produce laryngeal and pharyngeal sounds. Evidence drawn from numerous laryngoscopic studies demonstrates the scope of articulatory behaviours possible in the pharynx. For a broad sample of languages, lingual retraction is shown to accompany laryngeal/pharyngeal gestures, motivating the redistribution of vowel quality designations. The vocal tract is divided into two articulatory components: the laryngeal articulator and the oral articulator. The vowel chart is split into three sectors: front, raised, and retracted. Whereas front vowels can be qualified as close or open, so-called back vowels are re-designated as either raised or retracted, and the role of retraction as a function of the laryngeal constrictor mechanism is elaborated.
