Prosodic marking of focus in Nafsan

Languages use a variety of means to realise informational structure categories like topicalisation and focus. The interaction between prosody and focus realisation strategies was examined in Nafsan, a Southern Oceanic language of Vanuatu, in a series of tasks that were designed to explore prosodic realisation of informational and contrastive focus on nouns that were subjects or objects in mini-dialogues where word-order was manipulated. All speakers produced utterance-initial or utterance-final focal elements with a major pitch movement associated with the focused noun (subject or object). Focused nouns were also realised with a wider pitch and often realised in their own prosodic phrase compared to the same item in non-focal contexts. There was also significant syllable lengthening at the right edge of in-focus words. In utterance-initial contexts, post-focal material in Nafsan was almost always produced in a relatively compressed pitch range and there was evidence of de-phrasing of non-focal nouns regardless of utterance position, suggesting prosodic phrasing patterns similar to other languages with edge-marking prominence.
