Listeners use linguistic information and real-world knowledge to predict upcoming spoken words. However, studies of predictive processing have focused on prediction under optimal listening conditions. We examined the effect of foreign-accented speech on predictive processing. Furthermore, we investigated whether accent-specific experience facilitates predictive processing. Using the visual world paradigm, we demonstrated that although the presence of an accent impedes predictive processing, it does not preclude it. We further showed that as listener experience increases, predictive processing for accented speech increases and begins to approximate the pattern seen for native speech. These results speak to the limitation of the processing resources that must be allocated, leading to a trade-off when listeners are faced with increased uncertainty and more effortful recognition due to a foreign accent.
听众利用语言信息和现实世界知识来预测即将出现的口语单词。然而，预测性加工的研究主要集中在最佳听力条件下的预测。我们研究了带有外国口音的语音对预测性加工的影响。此外，我们还调查了特定口音的经验是否有助于预测性加工。使用视觉世界范式，我们证明，虽然口音的存在会阻碍预测性加工，但并不会阻止它。我们进一步表明，随着听众经验的增加，对口音语音的预测性加工也会增加，并开始接近对母语语音的加工模式。这些结果表明了必须分配的加工资源的局限性，当听众面临由于外国口音而增加的不确定性和更费力的识别时，这会导致一种权衡。
