Abstract

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.

脑瘫和构音障碍儿童的发声特点

目的：本研究旨在利用声乐发展阶段模型，调查脑瘫（CP）和构音障碍儿童的声乐特征：方法：对 39 名 4 岁左右患有脑性瘫痪和构音障碍的儿童的发声特点进行了分析。采用斯塔克早期发声发展评估-修订版进行感知编码分析，以检查发声的复杂性、波动性和辅音多样性：结果：儿童主要发出与声乐发展最早两个阶段相应的声音，其特点是发出类似元音的声音。他们对辅音特征的掌握有限，辅音多样性较低，发声频率也有不同程度的降低：我们的研究结果表明，CP 儿童因潜在的神经损伤而导致的肢体畸形会影响其言语运动的发展以及超越早期发声阶段的能力。这些研究结果突出表明，对于表现出类似发声特征的儿童，在超过预期发展时期后，考虑采用其他交流方式非常重要。

期刊介绍： Mission: JSLHR publishes peer-reviewed research and other scholarly articles on the normal and disordered processes in speech, language, hearing, and related areas such as cognition, oral-motor function, and swallowing. The journal is an international outlet for both basic research on communication processes and clinical research pertaining to screening, diagnosis, and management of communication disorders as well as the etiologies and characteristics of these disorders. JSLHR seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of communication sciences and disorders, including speech production and perception; anatomy and physiology of speech and voice; genetics, biomechanics, and other basic sciences pertaining to human communication; mastication and swallowing; speech disorders; voice disorders; development of speech, language, or hearing in children; normal language processes; language disorders; disorders of hearing and balance; psychoacoustics; and anatomy and physiology of hearing.
