The purpose of the present study was to investigate the consonant recognition of Mandarin-speaking children with cochlear implants (CIs) and hearing aids (HAs) and to determine if they reach a level of consonant recognition similar to that of normal-hearing (NH) children.
Little information is available in the literature regarding the consonant perception abilities of prelingually deafened young children with either CIs or HAs. No studies have compared Mandarin-Chinese consonant contrast recognition in CI and HA children.
Forty-one prelingually deafened children with CIs, 26 prelingually deafened children with HAs, and 30 NH children participated in this study. The 3 groups were matched for chronologic age (3-5 yr). The hearing-impaired groups were matched for age at fitting of the devices, duration of device use, and aided hearing threshold. All subjects completed a computerized Mandarin consonant phonetic contrast perception test.
CI and HA children scored, on average, approximately 8 percentage points below the mean NH group performance on the consonant contrast recognition. Approximately 40% of the CI and HA children had not reached a performance level of the NH group. No significant differences in the consonant recognition scores were found between the CI and HA groups. Age of implantation was correlated with consonant contrast recognition in the CI group.
When age at fitting of the devices, duration of device use, and aided thresholds are matched at the group level, consonant recognition is similar between the CI and HA children after 2 years of device use. Early implantation tends to yield better consonant contrast recognition in the young children with CIs. However, a large amount of variance in performance was not accounted for by the demographic variables studied.
本研究的目的是调查植入人工耳蜗（CI）和助听器（HA）的普通话儿童的辅音识别能力，并确定他们是否达到了正常听力（NH）儿童的辅音识别水平。
关于使用 CI 或 HA 的语前聋幼儿的辅音感知能力，文献中提供的信息很少。没有研究比较过 CI 和 HA 儿童的普通话辅音对比识别。
本研究纳入了 41 名语前聋 CI 儿童、26 名语前聋 HA 儿童和 30 名 NH 儿童。这 3 组儿童的年龄（3-5 岁）相匹配。听力受损组根据设备佩戴年龄、设备使用时间和助听听阈进行匹配。所有受试者均完成了普通话辅音语音对比感知测试。
CI 和 HA 儿童的平均得分比 NH 组低约 8 个百分点，在辅音对比识别方面。大约 40%的 CI 和 HA 儿童的表现没有达到 NH 组的水平。CI 和 HA 组之间的辅音识别得分无显著差异。植入年龄与 CI 组的辅音对比识别相关。
当设备佩戴年龄、设备使用时间和助听听阈在组水平上匹配时，在使用设备 2 年后，CI 和 HA 儿童的辅音识别能力相似。早期植入有助于提高 CI 儿童的辅音对比识别能力。然而，表现的大量差异无法用研究的人口统计学变量来解释。
