Abstract
Purpose: Oral and speech motor abilities are key components of assessments of Cantonese speakers with speech sound disorder (SSD), especially childhood apraxia of speech (CAS). This study aims to investigate the oral and speech motor abilities of Cantonese preschool children with and without SSD using an adapted version of a popular English assessment protocol.
Method: A total of 104 Cantonese-speaking children, aged between 3 and 5 years, were assigned to three main groups: typical development (TD), non-CAS SSD, and CAS. They were tested using the Cantonese Oral and Speech Motor Assessment (COSMA), an adapted version of the Robbins and Klee protocol. Sixteen perceptual and acoustic measures were employed to evaluate oral and speech motor abilities in the children, and binary logistic regression models were constructed to assess the predictive values of these measures for broad SSD diagnosis, combining the CAS and non-CAS SSD groups.
Results: Statistically significant differences were observed among the TD, non-CAS SSD, and CAS groups on seven COSMA measures, including measures of oral structures, speech and nonspeech oral functions, and speech motor abilities. Age progression was found on five measures. Total structural score and multisyllabic word accuracy emerged as significant predictors of broad SSD diagnosis.
Conclusions: This study supports the preliminary success of the COSMA in differentiating Cantonese preschool children with and without broad SSD. The TD group's performance offers a reference for local clinical use. Future research should include diverse groups of children with various SSD types to enhance understanding of oral and speech motor skills among Cantonese speakers and related clinical issues.
期刊介绍：
Mission: AJSLP publishes peer-reviewed research and other scholarly articles on all aspects of clinical practice in speech-language pathology. The journal is an international outlet for clinical research pertaining to screening, detection, diagnosis, management, and outcomes of communication and swallowing disorders across the lifespan as well as the etiologies and characteristics of these disorders. Because of its clinical orientation, the journal disseminates research findings applicable to diverse aspects of clinical practice in speech-language pathology. AJSLP 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 speech-language pathology, including aphasia; apraxia of speech and childhood apraxia of speech; aural rehabilitation; augmentative and alternative communication; cognitive impairment; craniofacial disorders; dysarthria; fluency disorders; language disorders in children; speech sound disorders; swallowing, dysphagia, and feeding disorders; and voice disorders.
