Emotions are often accompanied by vocalizations whose acoustic features provide information about the physiological state of the speaker. Here, we ask if perceiving these affective signals in one's own voice has an impact on one's own emotional state, and if it is necessary to identify these signals as self-originated for the emotional effect to occur. Participants had to deliberate out loud about how they would feel in various familiar emotional scenarios, while we covertly manipulated their voices in order to make them sound happy or sad. Perceiving the artificial affective signals in their own voice altered participants' judgements about how they would feel in these situations. Crucially, this effect disappeared when participants detected the vocal manipulation, either explicitly or implicitly. The original valence of the scenarios also modulated the vocal feedback effect. These results highlight the role of the exteroception of self-attributed affective signals in the emergence of emotional feelings.
情绪通常伴随着声音的表达，其声学特征提供了关于说话者生理状态的信息。在这里，我们想知道在自己的声音中感知到这些情感信号是否会影响自己的情绪状态，以及是否需要将这些信号识别为自我起源才能产生情感效应。参与者必须大声思考他们在各种熟悉的情绪场景中会有何感受，而我们则秘密地操纵他们的声音，以使他们的声音听起来高兴或悲伤。感知到自己声音中的人为情感信号改变了参与者对自己在这些情况下的感受的判断。至关重要的是，当参与者无论是明确地还是隐含地察觉到声音操纵时，这种影响就会消失。场景的原始效价也调节了声音反馈效应。这些结果突出了自我归因的情感信号的外感受在情感感受出现中的作用。
