成年人声道参数与身高的相关性
Correlations between vocal tract parameters and body heights in adult humans

为了评估成年人声道与身高的关系，该文采用声反射技术测量了19~30岁之间的109位男性和105位女性的声道形态数据，对声道的长度、体积和比例等8个声道参数与身高之间的相关性进行了研究。研究发现，成年人的声道参数存在显著的性别差异：男性的声道比女性的更长、更大；在咽腔和口腔的比例上，男性的咽腔相对更长、更大。声道与身高之间的关系存在一定的性别差异：男女被试的咽腔长度、咽腔体积、声道长度和声道体积等均与身高存在显著正相关；但整体上，女性声道参数与身高的相关程度高于男性，只有女性声道长度与身高的相关程度达到中度水平，其他均为低度水平。该结果对声纹鉴定领域中通过语音判断未知说话人的身高提供了一定的理论支持。
Abstract：The relationship between the adult speaker's vocal tract (VT) and their height was assessed using acoustic reflections to measure the VT morphometric data of 109 male subjects and 105 female subjects, aged 19-30 years. The heights were correlated with eight VT parameters, including VT length, volume and proportions. Significant gender differences for all eight VT parameters were found with the VTs of males being longer and larger than those of females. The pharynxes of males are relatively longer and larger parts of the oral cavity. Some gender differences were also found for correlations between the VT parameters and height. Specifically, both genders had significant positive correlations between the pharyngeal length, pharyngeal volume, VT length, VT volume and height with the correlations for females generally stronger than those for males. Only the female subjects' VT lengths showed moderate correlations with height, while all of the other correlations are quite weak. These findings provide theoretical support for estimating an unknown speaker's height based on their voice in forensic phonetics.
