由于说话者之间的差异，言语感知变得更加困难。因此，听者需要适应每个不同说话者的特定声音线索分布。将这种适应视为一种统计推断形式，我们探讨了听话者的先前期望在适应不熟悉的说话者中所起的作用。具体地说，我们测试了这样一种假设，即听者将更难适应其线索分布在说话者之间正常变化范围之外的说话者。我们还表明，基于对不同线索分布的适应模式，可以推断听者共享的先前期望。这为直接探测听者对说话者的先前期望提供了潜在的强大工具，而不依赖于许多不同说话者产生的语音，这些语音的收集和注释是昂贵的，并且仅间接地与听者的主观期望相关。
Speech perception is made much harder by variability between talkers. As a result, listeners need to adapt to each different talker’s particular acoustic cue distributions. Thinking of this adaptation as a form of statistical inference, we explore the role that listeners’ prior expectations play in adapting to an unfamiliar talker. Specifically, we test the hypothesis that listeners will have a harder time adapting to talkers whose cue distributions fall outside the range of normal variation across talkers. We also show that it is possible to infer listeners’ shared prior expectations based on patterns of adaptation to different cue distributions. This provides a potentially powerful tool for directly probing listeners’ prior expectations about talkers that does not rely on speech produced by many different talkers, which is costly to collect and annotate, and only indirectly related to listeners’ subjective expectations.
