Estimates of the prevalence of Speech and motor Speech Disorders in persons with complex neurodevelopmental Disorders.
Clinical linguistics & phonetics, 2019Co-Authors: Lawrence D. Shriberg, Edythe A. Strand, Kathy J. Jakielski, Heather L. MabieAbstract:Estimates of the prevalence of Speech and motor Speech Disorders in persons with complex neurodevelopmental Disorders (CND) can inform research in the biobehavioural origins and treatment of CND. The goal of this research was to use measures and analytics in a diagnostic classification system to estimate the prevalence of Speech and motor Speech Disorders in convenience samples of speakers with one of eight types of CND. Audio-recorded conversational Speech samples from 346 participants with one of eight types of CND were obtained from a database of participants recruited for genetic and behavioural studies of Speech sound Disorders (i.e., excluding dysfluency) during the past three decades. Data reduction methods for the Speech samples included narrow phonetic transcription, prosody-voice coding, and acoustic analyses. Standardized measures were used to cross-classify participants' Speech and motor Speech status. Compared to the 17.8% prevalence of four types of motor Speech Disorders reported in a study of 415 participants with idiopathic Speech Delay (SD), 47.7% of the present participants with CND met criteria for one of four motor Speech Disorders, including Speech Motor Delay (25.1%), Childhood Dysarthria (13.3%), Childhood Apraxia of Speech (4.3%), and concurrent Childhood Dysarthria and Childhood Apraxia of Speech (4.9%). Findings are interpreted to indicate a substantial prevalence of Speech Disorders, and notably, a substantial prevalence of motor Speech Disorders in persons with some types of CND. We suggest that diagnostic classification information from standardized motor Speech assessment protocols can contribute to research in the pathobiologies of CND.

Extensions to the Speech Disorders Classification System (SDCS)
Clinical linguistics & phonetics, 2010Co-Authors: Lawrence D. Shriberg, Edythe A. Strand, Nancy L Potter, Marios Fourakis, Sheryl D. Hall, Heather B. Karlsson, Heather L. Lohmeier, Jane L. Mcsweeny, Alison R. Scheer-cohen, Christie M. TilkensAbstract:This report describes three extensions to a classification system for paediatric Speech sound Disorders termed the Speech Disorders Classification System (SDCS). Part I describes a classification extension to the SDCS to differentiate motor Speech Disorders from Speech delay and to differentiate among three sub-types of motor Speech Disorders. Part II describes the Madison Speech Assessment Protocol (MSAP), an ∼ 2-hour battery of 25 measures that includes 15 Speech tests and tasks. Part III describes the Competence, Precision, and Stability Analytics (CPSA) framework, a current set of ∼ 90 perceptual- and acoustic-based indices of Speech, prosody, and voice used to quantify and classify sub-types of Speech Sound Disorders (SSD). A companion paper provides reliability estimates for the perceptual and acoustic data reduction methods used in the SDCS. The agreement estimates in the companion paper support the reliability of SDCS methods and illustrate the complementary roles of perceptual and acoustic methods in diagnostic analyses of SSD of unknown origin. Examples of research using the extensions to the SDCS described in the present report include diagnostic findings for a sample of youth with motor Speech Disorders associated with galactosemia, and a test of the hypothesis of apraxia of Speech in a group of children with autism spectrum Disorders. All SDCS methods and reference databases running in the PEPPER (Programs to Examine Phonetic and Phonologic Evaluation Records) environment will be disseminated without cost when complete.

“The Caterpillar”: A Novel Reading Passage for Assessment of Motor Speech Disorders
American journal of speech-language pathology, 2012Co-Authors: Rupal Patel, Kathryn Connaghan, Diana Franco, Erika Edsall, Dory Forgit, Laura Olsen, Lianna Ramage, Emily Tyler, Scott RussellAbstract:A review of the salient characteristics of motor Speech Disorders and common assessment protocols revealed the need for a novel reading passage tailored specifically to differentiate between and among the dysarthrias (DYSs) and apraxia of Speech (AOS). "The Caterpillar" passage was designed to provide a contemporary, easily read, contextual Speech sample with specific tasks (e.g., prosodic contrasts, words of increasing length and complexity) targeted to inform the assessment of motor Speech Disorders. Twenty-two adults, 15 with DYS or AOS and 7 healthy controls (HC), were recorded reading "The Caterpillar" passage to demonstrate its utility in examining motor Speech performance. Analysis of performance across a subset of segmental and prosodic variables illustrated that "The Caterpillar" passage showed promise for extracting individual profiles of impairment that could augment current assessment protocols and inform treatment planning in motor Speech Disorders.

Assessment of adult Speech Disorders: current situation and needs in French-speaking clinical practice
Logopedics Phoniatrics Vocology, 2021Co-Authors: Timothy Pommée, Mathieu Balaguer, Julie Mauclair, Julien Pinquier, Virginie WoisardAbstract:Introduction: Speech assessment methods used in clinical practice are varied and mainly perceptual and motor. Reliable assessment of Speech Disorders is essential for the tailoring of the patient's treatment plan. Objective: To describe current clinical practices and identify the shortcomings and needs reported by French-speaking clinicians regarding the assessment of Speech Disorders in adult patients. Methods: Data were collected using an online questionnaire for French-speaking Speech and language pathologists (SLPs) in Belgium, France, Switzerland, Luxembourg, and Maghreb. Forty-nine questions were grouped into six domains: participant data, educational and occupational background, experience with Speech Disorders, patient population, tools and tasks for Speech assessment, and possible lacks regarding the current assessment of Speech Disorders. Results: Responses from 119 clinicians were included in the analyses. SLPs generally use " a la carte" assessment with a large variety of tasks and Speech samples. About one quarter of them do not use existing assessment batteries. Those who do mostly use them partially. Pseudo-words are rarely used and are absent from standardized batteries, in contrast to the major use of words and sentences. Perceptual evaluation largely prevails (mainly overall ratings of Speech "intelligibility", "severity," and "comprehensibility" and percent-correct phonemes), whereas the recording equipment for acoustic measures is not standardized and only scarcely described by the SLPs. The most commonly used questionnaire to assess the functional impact of the Speech disorder is the Voice Handicap Index; one quarter of the SLPs does not use any questionnaire. Overall, the available tools are considered only moderately satisfactory. The main reported shortcomings are a lack of objectivity and reproducibility of Speech measures; exhaustiveness and consideration of specific Speech parameters (prosody, Speech rate, and nasality); practicality of the assessment tools. Conclusion: This study highlights a lack of standardization of the Speech assessment in French-speaking adults and the need to offer new reliable tools for an optimized, accurate Speech assessment. The automation of these tools would allow for rapid, reproducible, and accurate measures.

Factors influencing intelligibility and severity of chronic Speech Disorders of patients treated for oral or oropharyngeal cancer
European Archives of Oto-Rhino-Laryngology, 2019Co-Authors: Mathieu Balaguer, Aline Boisguerin, Anaïs Galtier, Nadège Gaillard, Michèle Puech, Virginie WoisardAbstract:Purpose Oral or oropharyngeal tumors degrade patients' Speech quality because of their location. The treatment of these cancers also affects the functional outcomes, depending on type (surgery, radiotherapy, chemotherapy), volume resection (according the size of the tumor) or on the anatomical area treated, and the post-treatment delay. The aim of this work is to determine the factors influencing the chronic Speech Disorders (in terms of intelligibility and severity) of patients treated for an oral or oropharyngeal cancer. Methods Speech-perceptive assessment was led by a panel of six expert Speech therapists, on a task of a description of a picture, presented to 87 patients. Clinical and treatment data were gathered by examining medical files. Results Intelligibility and severity scores in our population were 6.06 (interquartile range 4.2-8) and 7.61 (interquartile range 6.8-9.5) on a maximum of 10. After adjusting for age and anatomical region involved, multivariate analysis showed a principal impact of surgery on both intelligibility and severity, while the size of the tumor significantly affected the intel-ligibility score [− 143; 95% CI (− 2.21, − 0.65)]. These results are consistent with the definitions of intelligibility and severity of Speech Disorders. Conclusions The lack of information on the impact of tumor location, however, requires more work to contribute to reducing impact on the quality of life of patients.

Free sorting task of Speech Disorders by expert and non expert listeners
Revue de Laryngologie Otologie Rhinologie, 2012Co-Authors: Virginie Woisard, Pascal Gaillard, Danielle DuezAbstract:Understood the strategies underlying the perception of Speech motor Disorders (SMD) is useful for the management of people with this kind of Disorders. Our hypothesis was that intelligibility of Speech is a dramatic decision factor for the classification of Speech production independently of the type of listeners. Two types of listeners: 15 experts (logopedists and phoniatricians), and 15 non experts (students in the field of heath care without any experience) participated at this study performing a free sorting task of 33 stimuli. The stimuli are a sentence readed by 13 control subjects and 20 subjects with a SMD of several kinds of etiologies. The methodology used for the analysis is the visualization of proximity trees by a sorting mathematical algorithm and the analysis of the free commentaries as a discourse. The results confirm that the degree of alteration of intelligibility is the main factor distributed in the sorts, but the reference to the "normality" is an other strong criteria and this notion is frequently associated with a description of the stimuli at a level of voice more than a level of Speech. These results lead to a new hypothesis of a classification of perception of Speech included a Speech Disorders, determined at an extremity by a comparison with a "prototype of normality" and at the other extremity by the characteristic of "intelligibility or understandibility" reinforcing some concepts of Speech rehabilitation.

The prevalence of Speech disorder in primary school students in Yazd-Iran.
Acta medica Iranica, 2011Co-Authors: Sedighah Akhavan Karbasi, Razieh Fallah, Motaharah GolestanAbstract:Communication disorder is a widespread disabling problems and associated with adverse, long term outcome that impact on individuals, families and academic achievement of children in the school years and affect vocational choices later in adulthood. The aim of this study was to determine prevalence of Speech Disorders specifically stuttering, voice, and Speech-sound Disorders in primary school students in Iran-Yazd. In a descriptive study, 7881 primary school students in Yazd evaluated in view from of Speech Disorders with use of direct and face to face assessment technique in 2005. The prevalence of total Speech Disorders was 14.8% among whom 13.8% had Speech-sound disorder, 1.2% stuttering and 0.47% voice disorder. The prevalence of Speech Disorders was higher than in males (16.7%) as compared to females (12.7%). Pattern of prevalence of the three Speech Disorders was significantly different according to gender, parental education and by number of family member. There was no significant difference across Speech Disorders and birth order, religion and paternal consanguinity. These prevalence figures are higher than more studies that using parent or teacher reports.
