Abstract

Background and Aim: Consonant development plays a significant role in speech intelligibility which is impaired in children with profound hearing loss. Cochlear implant (CI) can facilitate the development of language comprehension and sound production in children with severe to profound sensorineural hearing loss. This study aimed to compare consonant production skills in children with CI and normal-hearing (NH) children aged 3–5 years. Methods: In this cross-sectional study, participants were 20 children with CI and 20 age- matched NH children. The consonant production skills were assessed using the speech intelligibility test in Persian. Results: There were significant differences between CI and NH children (p<0.05), where the highest percentage of correct production in both groups was related to the manner of articulation of stop and nasal consonants. NH children showed less accuracy only in /r/ and /ʧ/, while children with CI were less accurate in /q/, /x/, /ʤ/, /l/, /j/, and /r/. Conclusion: Children with CI have lower scores compared to age-matched NH peers, but they have similar consonant production skills. Keywords: Cochlear implant; consonant production; consonant accuracy

3-5岁植入人工耳蜗儿童与听力正常儿童辅音生成技能的比较

背景与目的:辅音发育在重度听力损失儿童的言语清晰度中起着重要的作用。人工耳蜗可以促进重度至重度感音神经性听力损失儿童语言理解和声音产生的发展。本研究旨在比较3-5岁CI患儿与正常听力患儿的辅音生成能力。方法:在这项横断面研究中，参与者是20名CI儿童和20名年龄匹配的NH儿童。使用波斯语语音清晰度测试评估辅音生成技能。结果:CI组与NH组之间存在显著性差异(p<0.05)，两组的正确产音率最高与顿音和鼻辅音的发音方式有关。NH患儿仅在/r/和/ ug /中表现出较低的准确性，而CI患儿在/q/、/x/、/ /、/l/、/j/和/r/中表现出较低的准确性。结论:CI患儿得分较同龄NH患儿低，但具有相近的辅音生成技能。关键词:人工耳蜗;辅音生产;辅音的准确性
