Driver (1996) reported that the ventriloquist illusion can enhance selective listening of speech. Participants in his study listened to target and distractor words from a single loudspeaker while watching lip movements of the target words on a video monitor either above the loudspeaker or displaced to the left or right. He found that participants were more accurate in repeating the target words when the video was displaced from the loudspeaker than when the video was directly above the loudspeaker. Driver proposed that the ventriloquist illusion dragged the target sounds toward the location of the lip movements, freeing them from interference from the distractor words. However, successful attempts at replicating this finding are rare (we know of only three successful replications from 19 attempts). In five experiments, we found a weak advantage for selective listening from displaced lip movements only when there was a convincing ventriloquist illusion. We conclude that the ventriloquist illusion is necessary to confer the advantage for selective listening from displaced lip movements but that the phenomenon is a fleeting one at best.
司机（1996 年）报告说，腹语错觉可以增强对言语的选择性倾听。在他的研究中，参与者在单一扬声器上收听目标词和干扰词，同时在视频监视器上观看目标词的唇动，视频监视器位于扬声器上方或向左或向右移动。他发现，当视频从扬声器上移开时，参与者在重复目标词时更准确，而当视频直接在扬声器上方时则不准确。司机提出，腹语错觉将目标声音拖向唇动的位置，使它们免受干扰词的干扰。然而，成功复制这一发现的尝试很少（我们仅从 19 次尝试中知道三次成功的复制）。在五项实验中，我们发现，只有在存在令人信服的腹语错觉的情况下，从偏离的唇动中选择性倾听才具有微弱的优势。我们的结论是，腹语错觉是赋予从偏离的唇动中选择性倾听优势所必需的，但这种现象充其量只是短暂的。
