The vocalizations of seven normally hearing (NH) and seven severely hearing-impaired (HI) infants were compared to find out the influence of auditory feedback on preverbal utterances. It was tested whether there are general differences in vocalizations between NH and HI infants, and whether specific emotional states affect the vocal production of NH and HI infants in the same way. First, the acoustic structure of the three most common vocal types was analyzed; second, the composition of vocal sequences was examined. Vocal sequence composition turned out to be more affected by hearing impairment than the acoustic structure of single vocalizations. This result indicates that the acoustic structure of preverbal vocalizations is to a great extent predetermined, whereas the composition of vocal sequences is influenced by auditory input.
对七名听力正常（NH）的婴儿和七名重度听力受损（HI）的婴儿的发声进行了比较，以探究听觉反馈对言语前发声的影响。测试了NH和HI婴儿在发声方面是否存在总体差异，以及特定情绪状态是否以相同方式影响NH和HI婴儿的发声。首先，分析了三种最常见发声类型的声学结构；其次，检查了发声序列的组成。结果表明，与单个发声的声学结构相比，听力障碍对发声序列组成的影响更大。这一结果表明，言语前发声的声学结构在很大程度上是预先确定的，而发声序列的组成则受听觉输入的影响。
