At the House Ear Institute, speech and language assessments are a regular part of the evaluation protocol for the cochlear implant clinical trials in children. The assessments are conducted preimplant and at specific postimplant intervals. Paired comparisons of the children's performance at pre- and post-implant intervals reveal significant improvements in both imitative and spontaneous speech production abilities. However, some differences between groups are noted. Children implanted at an early age demonstrate a greater number of significant improvements in speech production, while children using oral communication have better skills at all test intervals. In addition, significant improvements on three of the four receptive language measures and one of the four expressive language measures are demonstrated at the 6-mo postimplant test interval. A significant decrease in performance is noted for one receptive language measure. In a second study, the speech scores of control groups and postimplant groups of the same age (3, 4, or 5 yr) are compared. Implanted children score higher in all but one of 24 contrasts, and these differences are statistically significant in five of the comparisons.
在豪斯耳科研究所，言语和语言评估是儿童人工耳蜗临床试验评估方案的常规组成部分。这些评估在植入前和植入后的特定时间间隔进行。对儿童在植入前和植入后间隔期的表现进行配对比较，结果显示在模仿和自发言语产生能力方面都有显著改善。然而，各小组之间存在一些差异。幼年植入的儿童在言语产生方面有更多显著改善，而使用口语交流的儿童在所有测试间隔期都有更好的技能。此外，在植入后6个月的测试间隔期，四项接受性语言测量指标中的三项和四项表达性语言测量指标中的一项有显著改善。一项接受性语言测量指标的表现显著下降。在第二项研究中，比较了相同年龄（3岁、4岁或5岁）的对照组和植入后组的言语分数。植入儿童在24项对比中有23项得分更高，且在五项比较中这些差异具有统计学意义。
