New techniques for recording and analyzing speech movements have the potential to radically change existing approaches to speech assessment and management. Advances in motion capture hardware and software are now enabling a critical mass of researchers to comprehensively investigate speech motor performance in healthy and disordered populations. Although this technology is currently almost exclusively used for research, promising clinical applications are now emerging. In this paper, I briefly discuss the technological progression of current technologies used to record speech movements. I also highlight research in the Speech and Feeding Disorders Lab that is exploring ways to leverage this technology to assist with the assessment and management of motor speech disorders.

This chapter reviews speech motor impairments resulting from neurologic disorders, that is, dysarthria and apraxia of speech. The architecture of the brain’s speech motor network is used as a framework to describe the symptom patterns of the most relevant syndromes and their underlying pathomechanisms, with a focus on some of the more controversial issues. The chapter’s final section discusses whether speech motor impairments should be understood as domain-general dysfunctions of respiratory, laryngeal, and vocal tract movements, or as disorders of a motor system specialized for vocal communication.

Speech Motor

Assessments for acquired motor-speech disorders that look at movements of the articulators would appear at first glance to be universal. This may be true for the most basic non-speech aspects of movement. We argue that assessments for speech motor control must be attuned to language-specific variables to be fully valid. We describe the rationale for, and development of a motor-speech-disorder screening test for Swahili speakers which includes impairment measures as well as measures of intelligibility and speech-voice naturalness. We further describe its initial validation in terms of content validity, feasibility of administration and scoring without requirements for lengthy training and technical expertise and application to groups of people with and without Parkinson’s disease in Tanzania. Results indicate that the protocol is ready to use in so far as it is acceptable to users (clinicians, patients), is feasible to use, shows good interrater reliability, and is capable of differentiating performance in healthy speakers and those whose speech is disordered. We highlight needs for further development, including issues around training, development of local norms for healthy speakers and for speakers with a variety of neurological disturbances, and extension of the tool to cover culturally valid assessment of impact of communication disorders.

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.

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.

Primary Problem

Twenty-five "experts" on neurogenic motor speech disorders participated in a tutorial exercise. Each was given information on M, a patient who had communication difficulties as the result of stroke, and asked to complete a questionnaire about his problem. The information included a detailed case description, an audiotape of M's speech obtained at 4, 9, 13, and 17 days post-stroke, and test results from the Western Aphasia Battery, the Token Test, and a battery for apraxia of speech. The experts were in excellent agreement on M's primary problem, although it was called by seven different names. The experts were in poor agreement on his secondary problem(s), e.g., the presence and type of aphasia and dysarthria. The results suggest that labeling is difficult, even for "experts." Furthermore, the practicing clinician needs to be sensitive to the likelihood of more than one coexisting problem.
