PURPOSE
This study aimed to investigate the vocal characteristics of children with cerebral palsy (CP) and anarthria using the stage model of vocal development.
METHOD
Vocal characteristics of 39 children with CP and anarthria around 4 years of age were analyzed from laboratory-based caregiver-child interactions. Perceptual coding analysis was conducted using the Stark Assessment of Early Vocal Development-Revised to examine vocal complexity, volubility, and consonant diversity.
RESULTS
Children predominately produced vocalizations corresponding to the two earliest stages of vocal development characterized by vowel-like utterances. They showed a limited attainment of consonantal features with low consonant diversity and variably low vocal rates.
CONCLUSIONS
Our results demonstrate that underlying neurological impairments resulting in an anarthric status in children with CP affect the progression of speech motor development and their ability to advance beyond early vocal stages. These findings highlight the importance of considering alternative communication modalities for children demonstrating similar vocal characteristics beyond expected periods of development.
目的
本研究旨在使用言语发展阶段模型探讨脑瘫伴无言语儿童的嗓音特征。
方法
从基于实验室的照顾者-儿童互动中分析 39 名年龄在 4 岁左右的脑瘫伴无言语儿童的嗓音特征。使用经修订的 Stark 早期言语发展评估来进行感知编码分析，以检查嗓音复杂性、流利度和辅音多样性。
结果
儿童主要产生类似于言语发展的前两个阶段的嗓音，表现为元音样发声。他们仅达到了少量的辅音特征，辅音多样性低，嗓音率也存在差异。
结论
我们的结果表明，脑瘫伴无言语儿童的神经发育障碍影响了言语运动发育的进展，使其无法超越早期嗓音阶段。这些发现强调了对于表现出类似嗓音特征且已超出预期发展阶段的儿童，考虑替代交流方式的重要性。
