Swedish lexical word accents have been repeatedly said to have a low functional load. Even so, the language has kept these tones ever since they emerged probably over a thousand years ago. This article proposes that the primary function of word accents is for listeners to be able to predict upcoming morphological structures and narrow down the lexical competition rather than being lexically distinctive. Psycho- and neurophysiological evidence for the predictive function of word accents is discussed. A novel analysis displays that word accents have a facilitative role in word processing. Specifically, a correlation is revealed between how much incorrect word accents hinder listeners' processing and how much they reduce response times when correct. Finally, a dual-route model of the predictive use of word accents with distinct neural substrates is put forth.
瑞典语词汇重音一直被反复提及功能负荷较低。即便如此，自大约一千多年前这些声调出现以来，该语言一直保留着它们。本文提出，词汇重音的主要功能是让听众能够预测即将出现的形态结构并缩小词汇竞争范围，而非具有词汇区分性。文中讨论了支持词汇重音预测功能的心理和神经生理学证据。一项新的分析表明，词汇重音在词汇处理中具有促进作用。具体而言，揭示了不正确的词汇重音对听众处理的阻碍程度与正确时缩短反应时间的程度之间的相关性。最后，提出了一个具有不同神经基质的词汇重音预测性使用的双通道模型。
