摘要
目的本研究旨在调查儿童语言障碍(CAS)患儿与典型发育(TD)患儿相比的声学时空变异性。多项运动学研究已证实,与非言语障碍儿童相比,CAS 儿童的时空变异性更高。迄今为止,很少有研究使用声学信号对 CAS 的时空变异性进行调查。方法:数据来自参加在线研究的 10 名 CAS 儿童和 10 名 TD 儿童,他们的年龄从 5;0 到 11;2(岁;月)不等。所有患有 CAS 的儿童均已确诊,并在至少两项任务中表现出至少五种 CAS 特征,这些特征由两名精通 CAS 的语言病理学家独立确认。儿童重复 "给鲍比买只小狗"(BBAP)和 "妈妈抚摸小狗"(MPP)句子各 10 次。根据振幅包络线计算出的声时空指数 (STI) 用于研究声时空变异性。通过回归分析,我们分析了 STI 值的组间差异,同时对年龄和性别进行了控制。与 TD 儿童相比,MPP 显示 CAS 儿童的声学 STI 值明显更高。年龄和性别没有明显影响。这项研究为越来越多的实证数据增添了新的内容,这些数据表明,与 TD 儿童相比,CAS 儿童的语音时空控制更加多变。除了产生更多变化的语音外,CAS 儿童形成无语音错误的语音的能力也不稳定。这些发现还证明了利用远程数据收集来研究声学时空变异性的可行性,这样就可以招募更多的低发病率人群样本。补充材料https://doi.org/10.23641/asha.26814883。
Acoustic Analysis of Spatiotemporal Variability in Children With Childhood Apraxia of Speech.
PURPOSE
The purpose of this study was to investigate acoustic spatiotemporal variability in children with childhood apraxia of speech (CAS) compared to children with typical development (TD). Increased spatiotemporal variability in children with CAS relative to nonapraxic peers has been documented in multiple kinematic studies. To date, few studies have investigated spatiotemporal variability in CAS using an acoustic signal.
METHOD
Data were drawn from 10 children with CAS and 10 children with TD, ranging in age from 5;0 to 11;2 (years;months), who participated in an online study. All children with CAS had a verified diagnosis and showed at least five CAS features across at least two tasks, independently confirmed by two speech-language pathologists with expertise in CAS. Children repeated the sentences "Buy Bobby a puppy" (BBAP) and "Mom pets the puppy" (MPP) 10 times each. The acoustic spatiotemporal index (STI), calculated from the amplitude envelope, was used to investigate acoustic spatiotemporal variability. Using a regression analysis, we analyzed group differences in STI values while controlling for age and gender.
RESULTS
Children with CAS did not produce enough usable tokens of BBAP to analyze. MPP revealed significantly higher acoustic STI values in children with CAS compared to children with TD. No significant effects were observed for age or gender. Acoustic data collected online without the use of specialized equipment yielded high-quality audio data from which amplitude envelope tracing could be reliably accomplished.
CONCLUSIONS
This study adds to a growing body of empirical data indicating that children with CAS produce speech with more variable spatiotemporal control compared to children with TD. In addition to producing more variable speech, children with CAS were less consistently able to form productions free of phonetic errors. These findings also demonstrate the feasibility of using remote data collection to investigate acoustic spatiotemporal variability, which allows for the recruitment of larger samples of low-incidence populations.

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.
