OBJECTIVES
The main purpose of the present study was to compare the consonant error patterns of Dutch prelingually deaf CI children with prelingually hearing-impaired hearing aid (HA) children. The authors hypothesized that subjects using conventional hearing aids would have poorer consonant production skills. Additionally, the impact of the age at implantation (CI) and the degree of hearing loss (HA) was determined.
METHODOLOGY
This is a comparative study of 29 prelingually deaf CI children (m.a. 9;0 y) and 32 prelingually hearing-impaired HA children (m.a. 9;11 y) who received their first hearing aid before the age of 2 years. Nineteen CI children were implanted before the age of 5 years. Nine HA children had thresholds above 90dB (range: 91-105dB), 15 between 70 and 90dB (range: 72-90dB) and 8 below 70dB (range: 58-68dB). Speech samples of all the children were elicited by means of a picture naming test and were video-recorded for further phonetic and phonological analysis.
RESULTS
Considerably more phonetic and phonologic errors were observed in the HA children with thresholds above 70dB (range: 72-105dB). No notable differences could be found between deaf CI children and HA children with thresholds below 70dB. Even children implanted after the age of 5 years showed significantly fewer phonetic and phonological errors than HA children.
CONCLUSION
The consonant production of implanted children is more adequate than the consonant production of HA children with a hearing loss of 70dB or more. In addition, the results also indicate that even after the age of 5 years, implantation can still have an advantageous effect on a child's consonant production.
目的
本研究的主要目的是比较荷兰语先天性耳聋的人工耳蜗植入儿童与先天性听力受损的助听器儿童的辅音错误模式。作者假设使用传统助听器的受试者辅音发音技能较差。此外，还确定了植入年龄（人工耳蜗植入）和听力损失程度（助听器）的影响。
方法
这是一项对29名先天性耳聋的人工耳蜗植入儿童（平均年龄9岁0个月）和32名先天性听力受损的助听器儿童（平均年龄9岁11个月）的比较研究，这些儿童在2岁之前首次佩戴助听器。19名人工耳蜗植入儿童在5岁之前接受植入。9名助听器儿童的听阈高于90dB（范围：91 - 105dB），15名在70至90dB之间（范围：72 - 90dB），8名低于70dB（范围：58 - 68dB）。所有儿童的语音样本通过图片命名测试获取，并进行视频录制以便进一步进行语音和音系分析。
结果
在听阈高于70dB（范围：72 - 105dB）的助听器儿童中观察到明显更多的语音和音系错误。在耳聋的人工耳蜗植入儿童和听阈低于70dB的助听器儿童之间未发现显著差异。即使是5岁之后接受植入的儿童，其语音和音系错误也明显少于助听器儿童。
结论
人工耳蜗植入儿童的辅音发音比听力损失70dB或更高的助听器儿童更准确。此外，结果还表明，即使在5岁之后，植入仍然可以对儿童的辅音发音产生有利影响。
