Objetivo: realizar uma revisão bibliográfica sobre o atraso motor de fala não especificado, como ele é avaliado e ainda como se diferencia de outras desordens motoras da fala. Estratégia de pesquisa: Trata-se de uma revisão integrativa da literatura. Realizou-se a busca nas bases SciELO, PubMed, Medine e Scopus no mês de novembro de 2019. Para as quatro bases foram utilizados os seguintes construtos e descritores: “motor speech disorders” OR “childhood apraxia of speech” OR “childhood apraxia of speech cas” OR “developmental dyspraxia” OR “speech sound disorder” AND “speech motor control”, além da utilização de dois filtros: sujeitos até 18 anos e humanos. Critérios de seleção: Artigos publicados em português, inglês ou espanhol foram incluídos, sendo ou não de periódicos de acesso livre. Foram excluídos artigos que não estavam relacionados ao atraso motor de fala não especificado e estudos de revisão de literatura. Resultados: Foram encontrados56 artigos nas bases de dados, sendo 33 da base Scopus, 19 da PubMed, 3 da SciElo e 1 da Medline. Após análise e seleção pelos critérios de inclusão, foram selecionados 14 estudos. Posteriormente a leitura integral dos artigos, 8 estudos foram excluídos, pois não respondiam as perguntas norteadoras da pesquisa, obtendo-se um n de 6 estudos. Conclusão: Muitas crianças com atraso significativo na fala são diagnosticadas erroneamente, sendo o DMS-NOS a desordem de maior prevalência na infância.

Purpose Speech sound disorders and velopharyngeal dysfunction are frequent features of 22q11.2 deletion syndrome (22q). We report the first estimate of the prevalence of motor speech disorders (MSDs) in youth with 22q. Method Seventeen children and adolescents with 22q completed an assessment protocol that included a conversational speech sample. Data reduction included phonetic transcription, perceptual speech ratings, prosody-voice coding, and acoustic analyses. Data analyses included 3 motor speech measures and a cross-classification analytic. Prevalence estimates of speech and MSDs in youth with 22q were compared with estimates in speakers with other complex neurodevelopmental disorders: Down syndrome, fragile X syndrome, and galactosemia. Results Results indicated that 58.8% of the participants with 22q met criteria for speech delay, and 82.4% of the participants met criteria for MSDs, including 29.4% with speech motor delay, 29.4% with childhood dysarthria, 11.8% with childhood apraxia of speech, and 11.8% with concurrent childhood dysarthria and childhood apraxia of speech. MSDs were not significantly associated with velopharyngeal dysfunction. Conclusions In summary, 82.4% of the participants with 22q met criteria for 1 of 4 MSDs, predominantly speech motor delay and childhood dysarthria. Cross-validation of the present findings would support viewing MSDs as a core phenotypic feature of 22q.

The purpose of this paper is to outline a history and a possible future of speech science as a discipline. Two major and sometimes opposing views of speech science are discussed. One view is inspired by Stetson's work, and holds that study of speech movements is most likely to reveal the essentials of speech motor control. The other view regards the speech acoustic signal as part of the control mechanism; in this view, movements and the signals produced by them are intertwined as part of the control mechanism. The importance of understanding these two views of speech science is in the application of speech science skills to clinical disorders of speech motor control. The paper uses motor speech disorders as an example of how the two views can be joined empirically and theoretically for a maximally productive application of speech science to an understanding of disorders of speech motor control.

Purpose The goal of this article (PM I) is to describe the rationale for and development of the Pause Marker (PM), a single-sign diagnostic marker proposed to discriminate early or persistent childhood apraxia of speech from speech delay. Method The authors describe and prioritize 7 criteria with which to evaluate the research and clinical utility of a diagnostic marker for childhood apraxia of speech, including evaluation of the present proposal. An overview is given of the Speech Disorders Classification System, including extensions completed in the same approximately 3-year period in which the PM was developed. Results The finalized Speech Disorders Classification System includes a nosology and cross-classification procedures for childhood and persistent speech disorders and motor speech disorders (Shriberg, Strand, & Mabie, 2017). A PM is developed that provides procedural and scoring information, and citations to papers and technical reports that include audio exemplars of the PM and reference data used to standardize PM scores are provided. Conclusions The PM described here is an acoustic-aided perceptual sign that quantifies one aspect of speech precision in the linguistic domain of phrasing. This diagnostic marker can be used to discriminate early or persistent childhood apraxia of speech from speech delay.

Purpose The study of speech motor control has led to great advancements in the current understanding of childhood apraxia of speech (CAS). There remains a significant need to bridge the gap between theory and practice to fully understand the clinical implications of past research. Method This review article reviews the speech motor control research in CAS and discusses how these works have offered key information about the underlying motor deficits (Grigos et al., 2015; Terband et al., 2019), the influence of structured practice on speech performance (Case & Grigos, 2016; Grigos & Case, 2018), and the role of task complexity (Case, 2019; Case & Grigos, 2016; Grigos & Case, 2018). We highlight salient points from this existing literature and clinical implications to the assessment and treatment of CAS. Conclusion The study of speech motor control has shed light on a number of key factors related to CAS. Even within perceptually accurate speech, children with CAS display differences in movement patterning and timing control. Assessment must aim to more directly tax speech motor skills to obtain a thorough and accurate illustration of production deficits. Intervention is challenged with the task of not only improving production accuracy but also facilitating more efficient motor planning and programming. Motor-based intervention that applies motor learning principles and introduces variability across motor, phonetic, and prosodic contexts is believed to achieve this goal, though research is needed to better understand changes in speech motor control with treatment.

Core Features

Purpose Childhood apraxia of speech (CAS) is a speech disorder that many generalist speech-language pathologists feel underqualified to treat. For children with CAS, this may result in ad hoc interventions resulting in slower progress. Research evidence for various CAS treatments is primarily limited to single-case experimental design studies; however, two treatments (Rapid Syllable Transition Treatment [ReST] and the Nuffield Dyspraxia Programme, Third Edition) have been compared in a single randomized controlled trial. Conclusion This tutorial describes one of those treatments: ReST which was designed to address the three consensus core features of CAS simultaneously: consistency and accuracy of sounds, sequencing, and prosody. The treatment uses nonwords to help children build and store accurate motor plans and programs using principles of motor learning. Treatment data are described, and commonly reported clinical issues are discussed. Recommendations for which children may be suitable for ReST and for evidence-based practice are described.

Abstract This review visualizes the knowledge domain of motor speech disorders (MSDs) in linguistics between 2000 and 2019 by means of scientometric methods. With topic searches, the study collected 869 bibliographic records and 20, 411 references from Web of Science Core Collection (WoSCC) of Thomson Reuter. The clustered and visualized document co-citation network of the MSDs knowledge domain in CiteSpace identifies 15 research foci in different periods, including apraxia of speech, acoustics, children, technology, aphemia, childhood apraxia of speech, primary progressive aphasia, speech motor delay, Parkinson’s disease, amyotrophic lateral sclerosis, rhythm, foreign accent syndrome, phonation, phonological awareness, dose and speech perception. Revolving around linguistics, these foci could be divided into studies on speech characteristics of MSDs in terms of phonology and phonetics, remedies for MSDs in terms of neurolinguistics and acoustic phonetics, dysarthria secondary to neurological diseases based on pathological linguistics, subtypes of apraxia of speech, methods of MSDs based on auditory phonetics and a newly recognized subtype of MSDs. Meanwhile, the emerging trends of MSDs in linguistics are detected by the analysis of reference citation bursts, suggesting growing research in remedies for MSDs with the focus on assessments and effectiveness of treatments, speech characteristics and indexes of dysarthria secondary to neurological diseases and assistance to diagnose apraxia of speech. To sum up, the review has indicated that the acoustic measures to assess MSDs and acoustic remedies for dysarthria may not only be the past foci but also be future trends.

Speech sound disorders (SSDs) are commonly viewed as involving impaired articulation and/or phonological skills. Speech language pathologists working with individuals with (SSDs) assess the articulation of speech sounds and the coordination of articulatory structures with other components of the speech mechanism, including the phonatory, respiratory, and resonatory subsystems. The sound system of the language and the rules that govern how phonemes are combined are equally critical for clinicians to explore. While the terms “articulation” and “phonology” provide clinicians with a framework for classification, children who are broadly identified with (SSDs) may also display characteristics of a motor speech impairment, which can obscure the decision making process with respect to both diagnosis and treatment. One such motor speech disorder is childhood apraxia of speech (CAS). The focus of this paper is to discuss motor speech deficits in children and to review research that aims to distinguish motor speech patterns in children with (SSDs) with and without CAS. We will also address the relationship between emerging speech motor and linguistic skills.
