The purpose of this investigation was to determine the effect of speakers' attempts to disguise their voices on listeners' accuracy in judgments of height and weight. A total of six sentences were recorded by 26 speakers, 13 females and 13 males, under five conditions: in a normal manner (control condition) and in a manner in which they attempted to sound much taller and much shorter, as well as much heavier and much lighter than they actually were. Five master tapes were constructed, a control tape and four disguise tapes. Each tape contained a total of 156 sentences arranged in random order. A total of 40 judges, 20 in the height-estimation experiment and 20 in the weight-estimation experiment, participated in three sessions, one for each of the three master tapes (one control and two disguise tapes) in each experiment. They were asked to judge the height and weight of the speaker of each sentence and, using a seven-point confidence rating scale, to indicate the over-all confidence in their judgments at the end of each session. Although a majority of speakers yielded height and weight estimates consistent with the intended disguise conditions, the differences in listeners' estimates among all conditions were relatively small. Moreover, differences between speakers' actual heights and weights and listeners' height and weight estimates in the normal (control) condition were also relatively small. Implications of these findings and suggestions for future research are discussed.
本次调查的目的是确定说话者试图伪装自己声音对听众身高和体重判断准确性的影响。26名说话者（13名女性和13名男性）在五种条件下录制了总共六个句子：以正常方式（对照条件），以及试图让自己听起来比实际身高更高、更矮，比实际体重更重、更轻的方式。制作了五盘母带，一盘对照带和四盘伪装带。每盘磁带包含总共156个随机排列的句子。共有40名评委参与，20名参与身高估计实验，20名参与体重估计实验，他们参加了三个环节，每个实验中的三盘母带（一盘对照带和两盘伪装带）各进行一个环节。要求他们判断每个句子中说话者的身高和体重，并使用七点置信度评分量表，在每个环节结束时表明对自己判断的总体信心。尽管大多数说话者的身高和体重估计与预期的伪装条件一致，但所有条件下听众估计的差异相对较小。此外，在正常（对照）条件下，说话者的实际身高和体重与听众的身高和体重估计之间的差异也相对较小。讨论了这些发现的意义以及对未来研究的建议。
