Perceptual representations of phonemes are flexible and adapt rapidly to accommodate idiosyncratic articulation in the speech of a particular talker. This letter addresses whether such adjustments remain stable over time and under exposure to other talkers. During exposure to a story, listeners learned to interpret an ambiguous sound as [f] or [s]. Perceptual adjustments measured after 12 h were as robust as those measured immediately after learning. Equivalent effects were found when listeners heard speech from other talkers in the 12 h interval, and when they had the opportunity to consolidate learning during sleep.
音素的感知表征具有灵活性，能够迅速适应特定说话者语音中的特殊发音方式。本文探讨了这种调整在一段时间内以及在接触其他说话者的情况下是否保持稳定。在听一个故事的过程中，听众学会将一个模糊的声音解释为[f]或[s]。12小时后测量的感知调整与学习后立即测量的调整一样强烈。当听众在12小时间隔内听到其他说话者的语音时，以及当他们有机会在睡眠中巩固学习时，都发现了类似的效果。
