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.
