We describe an illusion in which a stranger's voice, when presented as the auditory concomitant of a participant's own speech, is perceived as a modified version of their own voice. When the congruence between utterance and feedback breaks down, the illusion is also broken. Compared to a baseline condition in which participants heard their own voice as feedback, hearing a stranger's voice induced robust changes in the fundamental frequency (F0) of their production. Moreover, the shift in F0 appears to be feedback dependent, since shift patterns depended reliably on the relationship between the participant's own F0 and the stranger-voice F0. The shift in F0 was evident both when the illusion was present and after it was broken, suggesting that auditory feedback from production may be used separately for self-recognition and for vocal motor control. Our findings indicate that self-recognition of voices, like other body attributes, is malleable and context dependent.
我们描述了一种错觉，即当一个陌生人的声音作为参与者自己说话的伴随听觉呈现时，会被感知为他们自己声音的一种变体。当话语和反馈之间的一致性被打破时，这种错觉也会被打破。与参与者听到自己的声音作为反馈的基线条件相比，听到陌生人的声音会导致他们产生的基频 (F0) 发生强烈变化。此外，F0 的变化似乎依赖于反馈，因为变化模式可靠地依赖于参与者自身 F0 和陌生人声音 F0 之间的关系。当错觉存在和消失时，F0 的变化都很明显，这表明来自产生的听觉反馈可能分别用于自我识别和声音运动控制。我们的研究结果表明，与其他身体属性一样，声音的自我识别是可塑的，并且依赖于环境。
