Previous work on language processing shows that listeners use context and word knowledge to understand speech, but debate continues over how context impacts low-level speech perception. The current study aimed to inform this debate by examining whether similar versus dissimilar semantic contexts affect speech perception. We proposed a model that low-level acoustic cues are integrated into the meaningful representations of words, and that listeners update their prediction of the upcoming word using contextual information during online processing. We studied word minimal pairs differing in one sound (i.e. bark vs. park) embedded in spoken sentences that were either semantically related or unrelated to each other in a dichotic listening task, while listeners decided which word they heard at the end of one sentence. Although we found some differences as a function of stimulus side (similar to previous work with dichotic listening tasks), our results did not provide clear evidence about the effect of high-level context on low-level speech.
