本报告的研究对象是听觉功能不同的同卵（同卵）双胞胎男孩。听力正常的人；另一个双侧听力严重受损。这些男孩提供了一个难得的机会来研究听力损失对声音发育的影响，并合理控制环境和遗传因素。这份初步报告的重点是他们在8个月、12个月和15个月的抽样年龄的声音发展。在8个月的样本（第一次记录的机会）中，两个男孩在咿呀学语方面的声学-语音差异是明显的，在12个月和15个月的后续样本中，他们之间的一些差异变得更大。主要的差异是：(a)发声元素的形成模式；(b)摩擦音、闪音和颤音的出现频率；(c)音节类型直方图；(d)元音用法的变化。这些数据对早期识别有沟通障碍风险的婴儿和理解婴儿语音发展中的听觉运动过程具有重要意义。
The subjects of this report are identical (monozygotic) twin boys who differ in auditory function. One has normal hearing; the other has a profound hearing loss bilaterally. These boys offered a rare opportunity to study the effects of hearing loss on vocal development with reasonable control over environmental and genetic factors. This initial report focuses on their vocal development over the sampled ages of 8, 12, and 15 months. Acoustic-phonetic differences in the babbling of the two boys were evident in the 8-month sample (the first recording opportunity), and some differences between them became greater over the succeeding samples at 12 and 15 months. The major differences were in (a) the formant patterns of vocalic elements; (b) the frequency of occurrence of fricatives, affricates, and trills; (c) histograms of syllable type; and (d) variation in vowel usage. The data hold implications for the early identification of infants at risk for communication disorder and for the understanding of auditory-motor processes in phonetic development during infancy.
