Self-cues such as one's own name or face attract attention, reflecting a bias for stimuli connected to self to be prioritized in cognition. Recent evidence suggests that even external voices can elicit this self-prioritization effect; in a voice-label matching task, external voices assigned to the Self-identity label 'you' elicited faster responses than those assigned to 'friend' or 'stranger' (Payne et al., Br. J. Psychology, 112, 585-610). However, it is not clear whether external voices assigned to Self are prioritized over participants' own voices. We explore this issue in two experiments. In Exp 1 (N = 35), a voice-label matching task comprising three external voices confirmed that reaction time and accuracy are improved when an external voice cue is assigned to Self rather than Friend or Stranger. In Exp 2 (N = 90), one of the voice cues was replaced with a recording of the participant's own voice. Reaction time and accuracy showed a consistent advantage for the participant's own-voice, even when it was assigned to the 'friend' or 'stranger' identity. These findings show that external voices can elicit self-prioritization effects if associated with Self, but they are not prioritized above individuals' own voices. This has implications for external voice production technology, suggesting own-voice imitation may be beneficial.
诸如自己的名字或面孔之类的自我线索会吸引注意力，这反映出在认知过程中对与自我相关的刺激进行优先处理的一种偏向。最近的证据表明，即使是外部声音也能引发这种自我优先效应；在一项语音标签匹配任务中，被分配到自我身份标签“你”的外部声音比被分配到“朋友”或“陌生人”的外部声音引发的反应更快（佩恩等人，《英国心理学杂志》，第112卷，第585 - 610页）。然而，尚不清楚分配给自我的外部声音是否比参与者自己的声音更具优先性。我们通过两个实验来探究这个问题。在实验1（N = 35）中，一个包含三种外部声音的语音标签匹配任务证实，当外部语音线索被分配给自我而非朋友或陌生人时，反应时间和准确性会得到提高。在实验2（N = 90）中，其中一个语音线索被替换为参与者自己声音的录音。即使参与者自己的声音被分配到“朋友”或“陌生人”身份，反应时间和准确性仍显示出一致的优势。这些发现表明，如果外部声音与自我相关联，它们可以引发自我优先效应，但它们并不比个人自己的声音更具优先性。这对外部语音生成技术具有启示意义，表明模仿自己的声音可能是有益的。
