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.

情绪通常伴随着发声，其声学特征提供有关说话者生理状态的信息。在这里，我们询问在自己的声音中感知这些情感信号是否会对自己的情绪状态产生影响，以及是否有必要将这些信号识别为自我产生的情绪影响。参与者必须大声思考他们在各种熟悉的情感场景中的感受，而我们则暗中操纵他们的声音，以使他们听起来快乐或悲伤。感知他们自己声音中的人工情感信号改变了参与者对他们在这些情况下的感受的判断。至关重要的是，当参与者明确或隐含地检测到声音操纵时，这种效果就会消失。. 这些结果突出了自我归因情感信号的外感受在情绪感受的出现中的作用。
