为了确定晚发性标准牙牙学语是否可以作为判断听力障碍风险的标准，我们从94名听力正常的婴儿和37名重度至重度听力障碍的婴儿中纵向获取了发声样本。家长们被要求报告孩子开始咿呀学语的情况（如“da,'' ''na,'' ''bee,'' ''yaya”等结构良好的音节的产生）。在实验室录音中收集了婴儿发出标准音节的证据。听力正常的婴儿在11个月前（范围3 - 10个月，模式7个月）就能产生标准的发声；失聪的婴儿直到11个月或更大的时候才会产生标准音节，通常会一直持续到生命的第三年（范围，11到49个月；模式，24个月）。正常阶段开始年龄与听觉放大年龄的相关系数为0.68，说明早期识别和配戴助听器对婴幼儿语言学习有显著的益处。正常听力婴儿和听力障碍婴儿的典型咿呀学语的发病分布没有重叠，这一事实意味着，健康婴儿在11个月前不能发出标准音节，应被视为听力障碍的一个严重风险因素，一旦发现，应立即转诊进行听力学评估。
To determine whether late Onset of canonical babbling could be used as a criterion to determine risk of hearing impairment, we obtained vocalization samples longitudinally from 94 infants with normal hearing and 37 infants with severe to profound hearing impairment. Parents were instructed to report the onset of canonical babbling (the production of well-formed syllables such as ''da,'' ''na,'' ''bee,'' ''yaya''). Verification that the infants were producing canonical syllables was collected in laboratory audio recordings. Infants with normal hearing produced canonical vocalizations before 11 months of age (range, 3 to 10 months; mode, 7 months); infants who were deaf failed to produce canonical syllables until 11 months of age or older, often well into the third year of life (range, 11 to 49 months; mode, 24 months). The correlation between age at onset of the canonical stage and age at auditory amplification was 0.68, indicating that early identification and fitting of hearing aids is of significant benefit to infants learning language. The fact that there is no overlap in the distribution of the onset of canonical babbling between infants with normal hearing and infants with hearing impairment means that the failure of otherwise healthy infants to produce canonical syllables before 11 months of age should be considered a serious risk factor for hearing impairment and, when observed, should result in immediate referral for audiologic evaluation.
