This study examines the ability of listeners to judge speaker height and weight from speech samples. Although previous investigations indicate that listeners are consistent in estimating body characteristics, it is not known which speech signal parameters are being used by the listeners for such estimates. Therefore, a series of listening tests was carried out in which male and female listeners judged the height and weight from male and female speakers reading isolated words and two text paragraphs. Both speaker sex and listener sex turned out to be important factors: Significant correlations between estimated height/weight and actual height/weight were found only for male speakers. The majority of these estimates came from the male listeners. Neither male nor female listeners, however, were able to estimate female speaker height or weight. Regression analysis involving F0, formant frequencies, energy below 1 kHz, and speech rate showed no significant correlations between these parameters and actually measured speaker height and weight, the only exception being a significant correlation between male speaker weight and speech rate. Furthermore, regression data suggested that the listeners (correctly) used speech rate information in judging male speaker weight, whereas low F0 and formant frequency values (wrongly) were taken to indicate large speaker body dimensions.
本研究考察了听众根据语音样本判断说话者身高和体重的能力。尽管先前的调查表明听众在估计身体特征方面具有一致性，但尚不清楚听众用于此类估计的是哪些语音信号参数。因此，进行了一系列听力测试，让男性和女性听众根据男性和女性说话者朗读单个单词和两段文本的语音来判断身高和体重。结果发现，说话者性别和听众性别都是重要因素：仅在男性说话者中，估计身高/体重与实际身高/体重之间存在显著相关性。这些估计大多来自男性听众。然而，无论是男性听众还是女性听众，都无法估计女性说话者的身高或体重。涉及基频（F0）、共振峰频率、1千赫兹以下能量和语速的回归分析表明，这些参数与实际测量的说话者身高和体重之间没有显著相关性，唯一的例外是男性说话者体重与语速之间存在显著相关性。此外，回归数据表明，听众（正确地）在判断男性说话者体重时使用了语速信息，而低基频和共振峰频率值（错误地）被认为表明说话者身材高大。
