该研究的目的是：1）比较2岁重听儿童（HH）与听力正常儿童（NH）的言语发声能力，2）确定HH儿童个体的风险来源，3）确定2岁时的言语发声技能是否可预测3岁时的言语发声技能。70名使用助听器的双侧轻度至重度听力损失儿童和37名年龄和SES匹配的NH儿童参加了研究。在2岁和3岁时评估儿童的语音产生能力。在两岁时，HH组表现出与NH组同龄人相当的元音产生能力，但辅音产生能力较弱。在HH组中，更好的结果与6个月大时的助听器配件，听力损失低于45 dB HL，词汇评分更高以及女性相关。2岁和3岁儿童的言语发声能力之间存在正相关。结合人口统计学、听力学和语言学变量对早期言语发声能力进行评估，可能有助于识别存在言语发声延迟风险的HH儿童。
The purpose of the study was to 1) compare the speech sound production abilities of 2-year-old children who are hard of hearing (HH) to children with normal hearing (NH), 2) identify sources of risk for individual children who are HH, and 3) determine whether speech sound production skills at age two were predictive of speech sound production skills at age three. Seventy children with bilateral, mild-to-severe hearing loss who use hearing aids and 37 age- and SES-matched children with NH participated. Children’s speech sound production abilities were assessed at 2 and 3 years of age. At age two, the HH group demonstrated vowel production abilities on par with their NH peers, but weaker consonant production abilities. Within the HH group, better outcomes were associated with hearing aid fittings by 6 months of age, hearing loss of less than 45 dB HL, stronger vocabulary scores, and being female. Positive relationships existed between children’s speech sound production abilities at 2 and 3 years of age. Assessment of early speech sound production abilities in combination with demographic, audiologic, and linguistic variables may be useful in identifying HH children who are at risk of delays in speech sound production.
