自我认知对于成功的社会沟通是不可或缺的，是当前社会神经科学研究的重点。自我的身体方面最典型地表现在面部和声音上。与大量关于自我面孔识别的研究相比，自我语音识别（SVR）尚未受到重视。越来越多的证据表明，基频（F0）和形成峰结构是其他声音识别（OVR）的关键声学线索。然而，很少有人知道，以及如何，声音线索被用于SVR而不是OVR。为了解决这个问题，我们独立地操纵了录制声音的F0和formant信息，并调查了它们对SVR和OVR的贡献。研究人员向日本参与者展示了录制好的声音刺激，并要求他们识别说话者——要么是他们自己，要么是他们的同伴。6组5名同性同伴参与了这项研究。在完全保留波形信息和仅保留低于第三波形（F3）的频率的条件下，随着F0的调制，SVR的精度显著下降，结果与OVR相当。而在只保留高于F3的频率时，在F0调制范围内，SVR的精度显著高于OVR， F0对SVR和OVR的精度几乎没有影响。我们的研究结果表明，尽管SVR和OVR都涉及F0和形成峰信息，但SVR的优势只有在缺乏语音可理解性的主要形成峰信息时才会表现出来。这些发现暗示了自我声音表征的稳健性，可能是由于听觉熟悉和其他因素，如与运动/发音表征的关联。
Self-recognition, being indispensable for successful social communication, has become a major focus in current social neuroscience. The physical aspects of the self are most typically manifested in the face and voice. Compared with the wealth of studies on self-face recognition, self-voice recognition (SVR) has not gained much attention. Converging evidence has suggested that the fundamental frequency (F0) and formant structures serve as the key acoustic cues for other-voice recognition (OVR). However, little is known about which, and how, acoustic cues are utilized for SVR as opposed to OVR. To address this question, we independently manipulated the F0 and formant information of recorded voices and investigated their contributions to SVR and OVR. Japanese participants were presented with recorded vocal stimuli and were asked to identify the speaker—either themselves or one of their peers. Six groups of 5 peers of the same sex participated in the study. Under conditions where the formant information was fully preserved and where only the frequencies lower than the third formant (F3) were retained, accuracies of SVR deteriorated significantly with the modulation of the F0, and the results were comparable for OVR. By contrast, under a condition where only the frequencies higher than F3 were retained, the accuracy of SVR was significantly higher than that of OVR throughout the range of F0 modulations, and the F0 scarcely affected the accuracies of SVR and OVR. Our results indicate that while both F0 and formant information are involved in SVR, as well as in OVR, the advantage of SVR is manifested only when major formant information for speech intelligibility is absent. These findings imply the robustness of self-voice representation, possibly by virtue of auditory familiarity and other factors such as its association with motor/articulatory representation.
