We investigated the relation between action and perception in speech processing, using the shadowing task, in which participants repeat words they hear. In support of a tight perception-action link, previous work has shown that phonetic details in the stimulus influence the shadowing response. On the other hand, latencies do not seem to suffer if stimulus and response differ in their articulatory properties. The present investigation tested how perception influences production when participants are confronted with regional variation. Results showed that participants often imitate a regional variation if it occurs in the stimulus set but tend to stick to their variant if the stimuli are consistent. Participants were forced or induced to correct by the experimental instructions. Articulatory stimulus-response differences do not lead to latency costs. These data indicate that speech perception does not necessarily recruit the production system.
我们使用跟读任务研究了言语加工中动作与感知之间的关系，在该任务中参与者重复他们听到的单词。支持紧密的感知 - 动作联系的是，先前的研究表明刺激中的语音细节会影响跟读反应。另一方面，如果刺激和反应在发音特性上不同，反应潜伏期似乎不受影响。本研究测试了参与者面对地域差异时感知如何影响产出。结果表明，如果刺激集中出现地域差异，参与者通常会模仿该差异，但如果刺激一致，他们则倾向于坚持自己的变体。参与者会被实验指令强制或诱导进行纠正。发音上的刺激 - 反应差异不会导致潜伏期增加。这些数据表明言语感知不一定会调用产出系统。
