The present study investigates to what extent acoustic cues to word stress facilitate both offline and online word processing in Papuan Malay. Previous production research has shown acoustic evidence for word-stress patterns in this language, counter to earlier predictions. A discussion of the literature on word stress perception and word stress in Papuan Malay is provided and complemented with reports of three word recognition tasks. The first two presented sequences of acoustically manipulated syllable dyads to native listeners in an offline word recognition task. This was done in order to investigate the individual contribution of each of the acoustic cues (F0, duration, intensity, spectral tilt) to the perception of word stress. F0 appeared a relevant cue when stimuli were embedded in a phrase, not in isolation. A follow-up reaction time experiment (online processing) investigated to what extent word recognition was facilitated when either an acoustically weak or an acoustically strong syllable was the cue to identify a word. Reaction times were shorter for strong syllables than for weak syllables. The outcomes suggest that Papuan Malay has a form of perceptually relevant word stress, which is particularly salient for irregular (ultimate) stress rather than for regular (penultimate) stress.
本研究旨在探讨在巴布亚马来语中，音系线索在多大程度上促进离线和在线的单词处理。先前的产生研究已经为这种语言的词重音模式提供了声学证据，这与早期的预测相悖。本文提供了关于词重音感知和巴布亚马来语词重音的文献综述，并补充了三个单词识别任务的报告。前两个任务在离线单词识别任务中向本地听众呈现了经过声学处理的音节对序列，以调查每个声学线索（基频、时长、强度、频谱倾斜）对词重音感知的单独贡献。当刺激嵌入短语中而不是孤立时，基频似乎是一个相关的线索。后续的反应时实验（在线处理）则调查了在识别单词时，弱音节或强音节作为线索，在多大程度上促进了单词识别。强音节的反应时间比弱音节短。研究结果表明，巴布亚马来语有一种具有感知相关性的词重音，这种重音对于不规则（终极）重音尤其明显，而不是对于规则（前级）重音。
