Phonological and phonetic properties of nasal substitution in Sasak and Javanese

Abstract

Austronesian languages such as Sasak and Javanese have a pattern of morphological nasal substitution, where nasals alternate with homorganic oral obstruents—except that [s] is described as alternating with [ɲ], not with [n]. This appears to be an abstract morphophonological relation between [s] and [ɲ] where other parts of the paradigm have a concrete homorganic relation. Articulatory ultrasound data were collected of productions of [t, n, ʨ, ɲ], along with [s] and its nasal counterpart from two languages, from 10 Sasak and 8 Javanese speakers. Comparisons of lingual contours using a root mean square analysis were evaluated with linear mixed-effects regression models, a method that proves reliable for testing questions of phonological neutralization. In both languages, [t, n, s] exhibit a high degree of articulatory similarity, whereas postalveolar [ʨ] and its nasal counterpart [ɲ] exhibited less similarity. The nasal counterpart of [s] was identical in articulation to [ɲ]. This indicates an abstract, rather than concrete, relationship between [s] and its morphophonological nasal counterpart, with the two sounds not sharing articulatory place in either Sasak or Javanese.
