当听一个连续说话的人说话时，识别语音的速度比听混合说话的人更快。谈话者适应的促进是否依赖于听者对谈话者连续性的期望？在这里，我们测量了对单词进行快速识别任务时的反应时间。在两种情况下，我们通过改变说话人在单词对内的连续性概率来操纵听众对听到同一说话人的期望：同一说话人的试验概率高，不同说话人的试验概率低，反之亦然。无论听者对说话者连续性的期望如何，在同一说话者的实验中，单词识别速度更快。在后续实验中，我们测量了听者在三种情况下对一个说话者所说的两对单词的反应时间，这些情况操纵了人们对这个单词本身是否会被重复的预期。在这里，只有预期的单词重复会导致更快的反应时间。这些结果表明，说话者适应是一个前馈过程，在语音感知过程中自动发生。
Recognizing speech is faster when listening to speech from a single continuous talker than mixed talkers. Does facilitation from talker adaptation depend on listeners’ expectations about talker continuity? Here, we measured response times during a speeded word identification task for pairs of words. We manipulated listeners’ expectations about hearing the same talker by varying the probability of talker continuity within word pairs across two conditions: high probability of same-talker trials with rare different-talker trials or vice-versa. Word recognition was faster for sametalker trials, regardless of listeners’ expectations about talker continuity. In a follow-up experiment, we measured listeners’ response times to pairs of words spoken by one talker in three conditions that manipulated expectations about whether the word itself would be repeated. Here, only expected word repetitions led to faster response times. These results suggest that talker adaptation is a feed-forward process, occurring automatically during speech perception.
