PURPOSE
The objective of this pilot study was to investigate the relationship between infant vocal characteristics and later speech motor impairment in children at risk for cerebral palsy (CP) to inform the early prediction of speech motor impairment.
METHOD
Vocal complexity, volubility, and consonant inventories of 13 infants at risk of CP were examined at approximately 12 months. We examined their association with later levels of speech motor impairment as measured by the Viking Speech Scale (VSS).
RESULTS
Children in our sample with greater speech motor impairment at age 4 years produced lower rates of developmentally complex vocalizations in infancy but showed no significant differences in vocal stage attainment, volubility, or consonant diversity.
CONCLUSIONS
Our results are in line with trends found in prior literature examining vocal characteristics of infants at risk for speech motor involvement. These results can inform data-driven hypotheses in future studies aimed at the early prediction of speech motor impairment through the study of infant vocal production.
目的
本初步研究的目的是调查脑瘫（CP）高危儿童的婴儿期发声特征与后期言语运动障碍之间的关系，为言语运动障碍的早期预测提供依据。
方法
在大约12个月时检查了13名CP高危婴儿的发声复杂性、流畅性和辅音清单。我们研究了它们与后来通过维京言语量表（VSS）测量的言语运动障碍水平之间的关联。
结果
我们样本中4岁时言语运动障碍较重的儿童在婴儿期产生发育性复杂发声的频率较低，但在发声阶段达到情况、流畅性或辅音多样性方面没有显著差异。
结论
我们的结果与先前研究言语运动受累高危婴儿发声特征的文献中发现的趋势一致。这些结果可为未来旨在通过研究婴儿发声来早期预测言语运动障碍的研究中基于数据的假设提供依据。
