The existence of word stress in Indonesian languages has been controversial. Recent acoustic analyses of Papuan Malay suggest that this language has word stress, counter to other studies and unlike closely related languages. The current study further investigates Papuan Malay by means of lexical (non-acoustic) analyses of two different aspects of word stress. In particular, this paper reports two distribution analyses of a word corpus, 1) investigating the extent to which stress patterns may help word recognition and 2) exploring the phonological factors that predict the distribution of stress patterns. The facilitating role of stress patterns in word recognition was investigated in a lexical analysis of word embeddings. The results show that Papuan Malay word stress (potentially) helps to disambiguate words. As for stress predictors, a random forest analysis investigated the effect of multiple morpho-phonological factors on stress placement. It was found that the mid vowels /ɛ/ and /ɔ/ play a central role in stress placement, refining the conclusions of previous work that mainly focused on /ɛ/. The current study confirms that non-acoustic research on stress can complement acoustic research in important ways. Crucially, the combined findings on stress in Papuan Malay so far give rise to an integrated perspective to word stress, in which phonetic, phonological and cognitive factors are considered.
印尼语中是否存在重音一直存在争议。最近对巴布亚马来语的声学分析表明，该语言存在重音，与其他研究相反，也与密切相关的语言不同。本研究通过对重音的两个不同方面的词汇（非声学）分析进一步研究了巴布亚马来语。具体来说，本文报告了对词库的两个分布分析，1）研究重音模式在多大程度上有助于单词识别，以及 2）探索预测重音模式分布的音系因素。在词嵌入的词汇分析中，研究了重音模式在单词识别中的促进作用。结果表明，巴布亚马来语的重音（可能）有助于区分单词。至于重音预测器，随机森林分析研究了多个形态音位因素对重音位置的影响。结果发现，中元音/ɛ/和/ɔ/在重音位置中起着核心作用，这完善了之前主要集中在/ɛ/上的工作的结论。目前的研究证实，重音的非声学研究可以在重要方面补充声学研究。至关重要的是，迄今为止，关于巴布亚马来语重音的综合研究结果提出了一个综合的重音视角，其中考虑了语音、音系和认知因素。
