Very few published studies have reported auditory speech perception in Hindi children with pre-lingual hearing loss. The study is aimed at comparing the speech perception skills of Hindi speaking children with pre-lingual severe to profound hearing loss using hearing aids and cochlear implants. Forty-three 6 to 8-year old children were included as participants, of which 22 were bilateral behind-the-ear hearing aid (HA) users and 21 were unilateral cochlear implant (CI) users. Speech perception was assessed through a forced-choice, picture-pointing task using recorded stimuli presented at 70 dB HL in the sound field. The skills assessed include: (a) pattern perception, (b) bisyllabic word identification, (c) monosyllabic word identification, (d) sentence identification and (e) minimal pair identification. Children using CI consistently performed significantly better than those with HA on all tasks. For the skills assessed, best performance was seen in pattern perception and poorest performance was seen in monosyllabic word identification. One participant from the CI group obtained ceiling scores for pattern perception and bisyllabic word identification. There was no statistically significant difference in the performance of 6 to 7 and 7 to 8-year-old children for any of the tasks. Children fitted with CI have better access to the cues important for perception of speech and hence perform consistently better than those using hearing aids. Recorded speech perception test can be used with children using cochlear implants and hearing aids.
很少有已发表的研究报道过患有语前听力损失的印地语儿童的听觉言语感知情况。这项研究旨在比较使用助听器和人工耳蜗的患有语前重度至极重度听力损失的印地语儿童的言语感知技能。43名6至8岁的儿童被纳入研究作为参与者，其中22名是双耳耳背式助听器（HA）使用者，21名是单侧人工耳蜗（CI）使用者。言语感知通过在声场中以70 dB HL呈现的录制刺激进行的强制选择、图片指认任务来评估。评估的技能包括：（a）模式感知，（b）双音节词识别，（c）单音节词识别，（d）句子识别和（e）最小对立体识别。在所有任务中，使用人工耳蜗的儿童始终比使用助听器的儿童表现显著更好。对于所评估的技能，模式感知表现最佳，单音节词识别表现最差。人工耳蜗组的一名参与者在模式感知和双音节词识别方面获得了满分。6至7岁和7至8岁儿童在任何任务中的表现均无统计学上的显著差异。佩戴人工耳蜗的儿童能更好地获取对言语感知很重要的线索，因此表现始终优于使用助听器的儿童。录制的言语感知测试可用于使用人工耳蜗和助听器的儿童。
