通过确定说话者的可懂度的连续体是假体的还是置换的，研究了直接幅度估计和间隔缩放程序用于评估听障成年人的言语可懂度的适当性。20名听力受损的谈话者的可懂度由20名听众使用直接幅度估计和20名听众使用间隔缩放。两组缩放数据相关的曲线的方式，是典型的假体连续，直接幅度估计比间隔缩放的语音清晰度更好的结构效度。
The appropriateness of direct magnitude estimation and interval scaling procedures for assessing the speech intelligibility of hearing-impaired adults was investigated by determining whether the continuum of the talkers' intelligibility was prothetic or metathetic. The intelligibility of 20 hearing-impaired talkers was scaled by 20 listeners using direct magnitude estimation and by 20 listeners using interval scaling. The two sets of scaling data were related in the curvilinear fashion that is typical of prothetic continua, indicating better construct validity for direct magnitude estimation than for interval scaling of speech intelligibility.
