Children's subjective judgments of speech clarity using the methods of paired comparisons and category rating were evaluated in this investigation. Eighty children with normal hearing between the ages of 4 and 8 years judged the clarity of sentences that were systematically bandpass-filtered using conditions that increased intelligibility as estimated by the Articulation Index. Subjects were classified into four age groups (4-, 5-, 6-, and 7-8-year age groups) with 20 subjects per group. With use of materials and training methods suitable for children, judgments were obtained via the two psychophysical procedures (10 subjects per age group for each procedure). Results indicated that children 5 years of age and older were able to make reliable clarity judgments using either procedure; however, the method of paired comparisons was more sensitive than category rating in detecting differences between the bandpass-filtered conditions.
本研究评估了儿童使用配对比较法和类别评定法对言语清晰度的主观判断。80名4至8岁听力正常的儿童对经过系统带通滤波的句子清晰度进行了判断，这些句子是在通过清晰度指数估计可懂度增加的条件下进行滤波的。受试者被分为四个年龄组（4岁、5岁、6岁和7 - 8岁年龄组），每组20名受试者。使用适合儿童的材料和训练方法，通过两种心理物理学程序（每个程序每个年龄组10名受试者）获得判断结果。结果表明，5岁及以上的儿童使用任何一种程序都能够做出可靠的清晰度判断；然而，在检测带通滤波条件之间的差异方面，配对比较法比类别评定法更敏感。
