OBJECTIVES
Recent research on the signal value of masculine physical characteristics in men has focused on the possibility that such characteristics are valid cues of physical strength. However, evidence that sexually dimorphic vocal characteristics are correlated with physical strength is equivocal. Consequently, we undertook a further test for possible relationships between physical strength and masculine vocal characteristics.
METHODS
We tested the putative relationships between White UK (N = 115) and Chinese (N = 106) participants' handgrip strength (a widely used proxy for general upper-body strength) and five sexually dimorphic acoustic properties of voices: fundamental frequency (F0), fundamental frequency's SD (F0-SD), formant dispersion (Df), formant position (Pf), and estimated vocal-tract length (VTL).
RESULTS
Analyses revealed no clear evidence that stronger individuals had more masculine voices.
CONCLUSIONS
Our results do not support the hypothesis that masculine vocal characteristics are a valid cue of physical strength.
目的
近期有关男性生理特征信号价值的研究集中于这样一种可能性，即这些特征是身体力量的有效线索。然而，有关性别二态性声音特征与身体力量相关的证据尚无定论。因此，我们进一步测试了身体力量与男性声音特征之间可能存在的关系。
方法
我们测试了英国白人（N=115）和中国人（N=106）参与者的握力（一种广泛用于代表上肢整体力量的指标）与声音的五个性别二态性声学特征之间的潜在关系：基频（F0）、基频标准差（F0-SD）、声道色散（Df）、声道位置（Pf）和估计的声道长度（VTL）。
结果
分析并未明确表明更强壮的个体具有更男性化的声音。
结论
我们的结果不支持这样一种假设，即男性化的声音特征是身体力量的有效线索。
