本研究的目的是创建并验证一套新的句子列表，用于评估听力损失听众在成人材料因难度或内容而不合适的情况下的言语感知能力。我们的目的是生成大量具有相同难度的句子列表，用于评估不同时间和不同条件下的表现。最初的儿科- azbio句子语料库包括一位女性说话者记录的450个句子。听力正常的幼儿园和一年级学生均能成功复述语料库中的所有句子。每个句子的平均可理解性是通过人工耳蜗模拟处理每个句子，并计算15名听力正常的听众获得的平均正确率得分来估计的。在按平均正确率对句子进行排序后，320个句子被分配到16个相同难度的列表中。然后，通过将所有句子列表以一种新颖的随机顺序呈现给听力损失的成人和儿童，来验证列表等效性。最后的验证阶段检查了在研究或临床环境中测试的成人和儿科听众的单列表比较。模拟研究的结果允许创建16个列表，每个列表包含20个句子。每个列表的平均可理解度从78.4%到78.7%不等。当16名成人人工耳蜗使用者和9名儿童助听器和人工耳蜗使用者的结果在列表之间没有显着差异时，验证了列表等效性。二项分布模型用于解释在列表中观察到的固有变异性。该模型还用于生成一个和两个列表比较的95%置信区间。对78名成人人工耳蜗使用者的361例和36名儿童人工耳蜗使用者的48例的回顾性分析显示，该模型得出的95%置信区间捕获了94%的应答（385/409）。人工耳蜗模拟被证明是估计单个句子可理解性的有效方法，用于评估人工耳蜗使用者。此外，还验证了用于构建等效句子列表和估计材料固有变异性的方法。因此，AzBio儿童句子表是等效的，适用于评估听力损失儿童的言语理解能力，以及对AzBio句子表现接近最低水平的成年人。
The goal of this study was to create and validate a new set of sentence lists that could be used to evaluate the speech perception abilities of listeners with hearing loss in cases where adult materials are inappropriate due to difficulty level or content. Our intention was to generate a large number of sentence lists with an equivalent level of difficulty for the evaluation of performance over time and across conditions. The original Pediatric-AzBio sentence corpus included 450 sentences recorded from one female talker. All sentences included in the corpus were successfully repeated by kindergarten and first grade students with normal hearing. The mean intelligibility of each sentence was estimated by processing each sentence through a cochlear implant simulation and calculating the mean percent correct score achieved by 15 normal-hearing listeners. After sorting sentences by mean percent correct scores, 320 sentences were assigned to 16 lists of equivalent difficulty. List equivalency was then validated by presenting all sentence lists, in a novel random order, to adults and children with hearing loss. A final-validation stage examined single-list comparisons from adult and pediatric listeners tested in research or clinical settings. The results of the simulation study allowed for the creation of 16 lists of 20 sentences. The average intelligibility of each list ranged from 78.4% to 78.7%. List equivalency was then validated, when the results of 16 adult cochlear implant users and 9 pediatric hearing aid and cochlear implant users revealed no significant differences across lists. The binomial distribution model was used to account for the inherent variability observed in the lists. This model was also used to generate 95% confidence intervals for one and two list comparisons. A retrospective analysis of 361 instances from 78 adult cochlear implant users and 48 instances from 36 pediatric cochlear implant users revealed that the 95% confidence intervals derived from the model captured 94% of all responses (385/409). The cochlear implant simulation was shown to be an effective method for estimating the intelligibility of individual sentences for use in the evaluation of cochlear implant users. Further the method used for constructing equivalent sentence lists and estimating the inherent variability of the materials has also been validated. Thus, the AzBio Pediatric Sentence Lists are equivalent and appropriate for the assessment of speech understanding abilities of children with hearing loss as well as adults for whom performance on AzBio sentences is near the floor.
