在谈话中，我们自己的话和别人的话是一个接一个的。周围环境对言语感知的影响有很好的记录，但是，尽管我们自己的声音无处不在，我们自己的言语是否也影响我们对其他说话者的感知还不清楚。这项研究通过6个实验研究了由我们自己的语音引起的语境效应，特别是针对速率归一化（即，相对于周围语音速率感知语音段）。实验1发现，听力预先记录的快速或缓慢的上下文句子改变了模糊元音的感知，复制早期的工作。实验2表明，在目标呈现之前以快或慢的速度说话也会改变目标感知，尽管先前的语速的影响被降低。实验3表明，沉默的谈话（即，内部语音）在快或慢的速度并没有调节他人的感知，这表明在实验2中的自我产生的语音速率的影响，通过监测外部语音信号。实验4表明，当参与者播放自己的（快/慢）的语音，没有减少前面的语音速率的影响，观察，这表明语音生产的额外任务可能是负责实验2中减少的效果。最后，实验5和6用新的参与者样本重复实验2和3。两者合计，这些结果表明，在语音产生的变化可能会导致语音感知的变化，从而进行我们的理解在对话环境中的口语交际的影响。
In conversation, our own speech and that of others follow each other in rapid succession. Effects of the surrounding context on speech perception are well documented but, despite the ubiquity of the sound of our own voice, it is unknown whether our own speech also influences our perception of other talkers. This study investigated context effects induced by our own speech through 6 experiments, specifically targeting rate normalization (i.e., perceiving phonetic segments relative to surrounding speech rate). Experiment 1 revealed that hearing prerecorded fast or slow context sentences altered the perception of ambiguous vowels, replicating earlier work. Experiment 2 demonstrated that talking at a fast or slow rate prior to target presentation also altered target perception, though the effect of preceding speech rate was reduced. Experiment 3 showed that silent talking (i.e., inner speech) at fast or slow rates did not modulate the perception of others, suggesting that the effect of self-produced speech rate in Experiment 2 arose through monitoring of the external speech signal. Experiment 4 demonstrated that, when participants were played back their own (fast/slow) speech, no reduction of the effect of preceding speech rate was observed, suggesting that the additional task of speech production may be responsible for the reduced effect in Experiment 2. Finally, Experiments 5 and 6 replicate Experiments 2 and 3 with new participant samples. Taken together, these results suggest that variation in speech production may induce variation in speech perception, thus carrying implications for our understanding of spoken communication in dialogue settings.
