To compare young cochlear implant (CI) recipients' consonant production accuracy with that of age- and gender-matched peers who were typically developing (TD). In addition to examining initial consonants, the authors compiled new data regarding the accuracy of final consonants and the order of consonant acquisition.
Eleven young CI recipients with 24 months of CI experience and 11 age- and gender-matched TD peers produced target words in short sentences. Consonant production accuracy was examined for total scores, initial and final word positions, and three developmental sound classes: Early, Middle, and Late.
Initial consonants were produced with relatively greater accuracy than were final consonants by the TD and CI groups. Whereas initial consonants appeared to be acquired in a typical order, descriptive data suggest that this might not be the case for final consonants.
Although still delayed compared to age-matched peers, young CI recipients showed substantial progress in consonant acquisition. Their accuracy levels after 2 years of CI experience support the notion that implantation at a young age has added value for phonological development.
比较年轻的耳蜗植入（CI）接受者与年龄和性别匹配的典型发育（TD）同龄人在辅音产生准确性方面的差异。除了检查初始辅音外，作者还汇编了有关辅音准确性和辅音习得顺序的新数据。
11 名具有 24 个月 CI 经验的年轻 CI 接受者和 11 名年龄和性别匹配的 TD 同龄人在短句中生成目标词。辅音产生准确性分别检查总分数、初始和最终单词位置以及三个发育音类：早期、中期和晚期。
TD 和 CI 组的初始辅音比终末辅音产生的准确性相对更高。虽然初始辅音似乎按典型顺序习得，但描述性数据表明，终末辅音可能并非如此。
尽管与年龄匹配的同龄人相比仍然存在延迟，但年轻的 CI 接受者在辅音习得方面取得了实质性的进展。他们在接受 CI 治疗 2 年后的准确性水平支持了这样一种观点，即在年幼时植入有助于语音发展。
