The perception of word stress cues in Papuan Malay: a typological perspective and experimental investigation.

Analyses of word prosody have shown that in some Indonesian languages listeners do not make use of word stress cues. The outcomes have contributed to the conclusion that these languages do not have word stress. The current study revisits this conclusion and investigates to what extent speakers of Papuan Malay, a language of Eastern Indonesia, use suprasegmental stress cues to recognize words. Acoustically, this language exhibits predictable word level prominence patterns, which could facilitate word recognition. However, the literature lacks a crucial perceptual verification and related languages in the Trade Malay family have been analysed as stressless. This could be indicative of either regional variation or different criteria to diagnose word stress. To investigate this issue, the current study reviews the literature on which criteria were decisive to diagnose (the absence of) word stress in Indonesian and Trade Malay. An acoustic analysis and a gating task investigate the usefulness of Papuan Malay stress cues for word recognition. Results show that Papuan Malay listeners are indeed able to use suprasegmental stress cues to identify words. The outcomes are discussed in a typological perspective to shed light on how production and perception studies contribute to stress diagnosis cross-linguistically.
