To determine the effect of speakers' attempts to disguise their voices on listeners' accuracy in age judgments, 26 speakers, 13 females and 13 males, recorded six sentences under three conditions: (a) in a normal manner, actually were, and (c) in a manner in which they attempted to sound much older than they actually were. Three master tapes were constructed, one for each of the three conditions. A total of 20 judges, 10 females and 10 males, participated in three sessions, one for each of the three master tapes. In each session they were asked to judge the age 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 age estimates consistent with the conditions of intended disguise, the differences in listeners' estimates among all three conditions were relatively small. Moreover, differences between speakers' actual ages and listeners' age estimates in the control condition were also small. Implications of the findings and suggestions for research are discussed.
为了确定说话者试图伪装自己声音对听众年龄判断准确性的影响，26名说话者（13名女性和13名男性）在三种条件下录制了六个句子：（a）以正常方式，（b）实际年龄的方式，以及（c）试图听起来比实际年龄大得多的方式。制作了三盘母带，每种条件一盘。共有20名评判员（10名女性和10名男性）参加了三个环节，每个环节对应一盘母带。在每个环节中，要求他们判断每个句子说话者的年龄，并使用七点置信度评分量表在每个环节结束时表明他们对自己判断的总体置信度。尽管大多数说话者的年龄估计与预期伪装条件一致，但所有三种条件下听众估计的差异相对较小。此外，在对照条件下，说话者的实际年龄与听众年龄估计之间的差异也很小。讨论了研究结果的意义和研究建议。
