Speech perception involves both conceptual cues and perceptual cues. These, individually, have been shown to guide bilinguals’ speech perception; but their potential interaction has been ignored. Explicitly, bilinguals have been given perceptual cues that could be predicted by the conceptual cues. Therefore, to target the perceptual-conceptual interaction, we created a restricted range of perceptual cues that either matched, or mismatched, bilinguals’ conceptual predictions based on the language context. Specifically, we designed an active speech perception task that concurrently collected electrophysiological data from Spanish–English bilinguals and English monolinguals to address the extent to which this cue interaction uniquely affects bilinguals’ speech sound perception and allocation of attentional resources. Bilinguals’ larger MMN-N2b in the mismatched context aligns with the Predictive Coding Hypothesis to suggest that bilinguals use their diverse perceptual routines to best allocate cognitive resources to perceive speech.

匹配错配：双语者言语感知中知觉和概念线索之间的相互作用

言语感知包括概念线索和知觉线索。这些，单独地，已被证明可以指导双语者的言语感知；但它们潜在的相互作用被忽略了。明确地，双语者获得了可以通过概念线索预测的感知线索。因此，为了针对感知-概念交互，我们创建了有限范围的感知线索，这些线索要么匹配，要么不匹配，双语者基于语言上下文的概念预测。具体来说，我们设计了一个主动语音感知任务，同时从西班牙语-英语双语者和英语单语者收集电生理数据，以解决这种提示交互对双语者语音感知和注意力资源分配的独特影响的程度。
