Variable linguistic environments require the ability to quickly update expectations and behavior including speech comprehension. This adaptive capacity is key to understanding how listeners successfully recognize speaker intentions in light of the ubiquitous variability in speech. The present study investigates how listeners' real-time sentence comprehension adapts to speaker-specific prosodic variability. In two forced choice mouse tracking experiments, listeners had to identify a visual referent guided by pre-recorded instructions. When exposed to a speaker that uses unconventional pitch accent placement, listeners discard intonational information for that speaker, but keep using intonation to resolve the referential ambiguity for another speaker that places pitch accents conventionally. These results show for the first time that intonationally guided sentence comprehension adapts in a speaker-sensitive way. The study further provides valuable first insights into the temporal unfolding of this adaptation process. Listeners first attribute unconventional patterns to the context, thus discarding the informational value of intonation for both speakers. After sufficient evidence, however, listeners start attributing unexpected patterns to only the unconventional speaker. Materials, data, and scripts can be retrieved here: http://osf.io/fdpg4

可变的语言环境要求能够快速更新期望和行为，包括语音理解。这种自适应能力是理解听众如何根据语音普遍存在的可变性成功识别说话者意图的关键。本研究调查了听众的实时句子理解如何适应说话者特定的韵律变异性。在两个强制选择鼠标跟踪实验中，听众不得不识别由预先记录的指令引导的视觉对象。当与使用非常规音高重音放置的说话者接触时，听众会丢弃该说话人的国家信息，但会继续使用语调来解决另一位通常按音高重音放置的说话人的参照歧义。这些结果首次表明，国际指导的句子理解以说话者敏感的方式适应。该研究进一步为这种适应过程的时间展开提供了有价值的初步见解。听众首先将非常规模式归因于上下文，从而放弃了两个讲话者的语调信息价值。但是，在获得足够的证据之后，听众才开始将意外的模式归因于非常规的说话者。可以在这里检索材料，数据和脚本：http://osf.io/fdpg4 因此放弃了两个说话者的语调信息价值。但是，在获得足够的证据之后，听众才开始将意外的模式归因于非常规的说话者。可以在这里检索材料，数据和脚本：http://osf.io/fdpg4 因此放弃了两个说话者的语调信息价值。但是，在获得足够的证据之后，听众才开始将意外的模式归因于非常规的说话者。可以在这里检索材料，数据和脚本：http://osf.io/fdpg4
