性选择似乎塑造了包括人类在内的不同物种的声音信号。特别是低沉、有共鸣的发声可能会吸引配偶和/或恐吓同性竞争者。在人类男性中，这些适应功能的证据主要来自感知研究，在这些研究中，声学参数是使用专业软件操纵的。这种方法提供了严格的实验控制，但提供的生态有效性很小，特别是当目标声学参数随其他参数自然变化时。此外，这样的实验研究没有提供关于说话人的声学变量所暗示的信息--也就是为什么在两性和中间性环境中，对声音提示的关注可能更受青睐。我们使用160名男性说话者的具有高生态效度的语音记录和状况的生物标志物，包括基线皮质醇和睾酮水平、身体形态和力量，测试了一系列与说话者的知觉和潜在状况有关的预先登记的假设。我们发现男性的基本频率(Fo)与女性的吸引力知觉和男性的优势知觉之间存在负的曲线和负的线性关系。此外，皮质醇和睾酮在预测fo方面存在负交互作用，力量和体型测量负向预测共振峰频率(Pf)。对当前结果和之前两个样本的荟萃分析证实，只有皮质醇水平较低的男性才能预测睾酮水平。这项研究为在性别选择的背景下注意男性的声音特征提供了可能的进化功能的经验证据。
Sexual selection appears to have shaped the acoustic signals of diverse species, including humans. Deep, resonant vocalizations in particular may function in attracting mates and/or intimidating same-sex competitors. Evidence for these adaptive functions in human males derives predominantly from perception studies in which vocal acoustic parameters were manipulated using specialist software. This approach affords tight experimental control but provides little ecological validity, especially when the target acoustic parameters vary naturally with other parameters. Furthermore, such experimental studies provide no information about what acoustic variables indicate about the speaker—that is, why attention to vocal cues may be favored in intrasexual and intersexual contexts. Using voice recordings with high ecological validity from 160 male speakers and biomarkers of condition, including baseline cortisol and testosterone levels, body morphology and strength, we tested a series of pre-registered hypotheses relating to both perceptions and underlying condition of the speaker. We found negative curvilinear and negative linear relationships between male fundamental frequency (fo) and female perceptions of attractiveness and male perceptions of dominance. In addition, cortisol and testosterone negatively interacted in predicting fo, and strength and measures of body size negatively predicted formant frequencies (Pf). Meta-analyses of the present results and those from two previous samples confirmed that fonegatively predicted testosterone only among men with lower cortisol levels. This research offers empirical evidence of possible evolutionary functions for attention to men’s vocal characteristics in contexts of sexual selection.
