本研究重点关注 34 名语前聋儿童的长期言语感知表现，这些儿童接受了 Cochlear Corporation 制造的多通道人工耳蜗植入物。这些儿童根据接受人工耳蜗植入的年龄进行分组，并根据他们每天使用设备的时间进行表征。连接外部植入硬件后，每年对儿童进行各种言语感知测试。在言语感知能力的封闭测试中，5 岁之前植入的儿童与 5 岁之后植入的儿童相比，在表现上没有明显差异。与术前相比，所有儿童的表现均有所改善。在 36 个月的测试间隔和 48 个月的测试间隔中，与 5 岁之后植入的儿童相比，5 岁之前植入的儿童的开放式单词识别性能明显更好。用户状态（由植入物的日常使用量定义）显着影响除模式感知之外的所有语音感知性能指标。
This study focused on the long-term speech perception performances of 34 prelingually deafened children who received multichannel cochlear implants manufactured by Cochlear Corporation. The children were grouped by the age at which they received cochlear implants and were characterized by the amount of time they used their devices per day. A variety of speech perception tests were administered to the children at annual intervals Following the connection of the external implant hardware. No significant differences in performance are evident for children implanted before age 5 compared to children implanted after age 5 on closed-set tests of speech perception ability All children demonstrated an improvement in performance compared to the pre-operative condition. Open-set word recognition performance is significantly better for children implanted before age 5 compared to children implanted after age 5 at the 36-month test interval and the 48-month test interval. User status, defined by the amount of daily use of the implant, significantly affects all measures of speech perception performance except pattern perception.
