Speech discrimination testing was completed on 30 adults with varying degrees of sensorineural hearing impairment. Tape recordings of four talkers' utterances of CID W-22 word lists served as the stimulus materials. Listeners' responses were scored independently by three experienced judges. For 26 of the 30 subjects, the difference between the lowest and highest word-discrimination score was 8% or greater. Variations in scores could not be attributed to a single talker but were spread across all talkers. A moderate negative correlation was found between each listener's average word-discrimination score and amount of variability among his or her individual scores. The statistical analysis indicated that talker differences were responsible for only a small portion of the variability in scores and suggested that a factor of greater importance is the talker-listener interaction.
对30名患有不同程度感音神经性听力障碍的成年人进行了言语辨别测试。以四名说话者朗读CID W - 22单词列表的录音作为刺激材料。三名经验丰富的评判员对听众的反应进行独立评分。在30名受试者中，有26名受试者的最低和最高单词辨别分数之差为8%或更高。分数的差异并非归因于某一个说话者，而是分布在所有说话者身上。在每个听众的平均单词辨别分数与其个人分数的变异性之间发现了适度的负相关。统计分析表明，说话者差异仅占分数变异性的一小部分，并表明更重要的因素是说话者与听众之间的互动。
