Speech Features

Abstract Speech disorders occur commonly in individuals with Down syndrome (DS), although data regarding the auditory-perceptual speech features are limited. This descriptive study assessed 47 perceptual speech features during connected speech samples in 26 children with DS. The most severely affected speech features were: naturalness, imprecise consonants, hyponasality, speech rate, inappropriate silences, irregular vowels, prolonged intervals, overall loudness level, pitch level, aberrant oropharyngeal resonance, hoarse voice, reduced stress, and prolonged phonemes. These findings suggest that speech disorders in DS are due to distributed impairments involving voice, speech sound production, fluency, resonance, and prosody. These data contribute to the development of a profile of impairments in speakers with DS to guide future research and inform clinical assessment and treatment.

The Relationship

Purpose This study was intended to document speech recovery for 1 person with acquired apraxia of speech quantitatively and on the basis of her lived experience. Method The second author sustained a traumatic brain injury that resulted in acquired apraxia of speech. Over a 2-year period, she documented her recovery through 22 video-recorded monologues. We analyzed these monologues using a combination of auditory perceptual, acoustic, and qualitative methods. Results Recovery was evident for all quantitative variables examined. For speech sound production, the recovery was most prominent during the first 3 months, but slower improvement was evident for many months. Measures of speaking rate, fluency, and prosody changed more gradually throughout the entire period. A qualitative analysis of topics addressed in the monologues was consistent with the quantitative speech recovery and indicated a subjective dynamic relationship between accuracy and rate, an observation that several factors made speech sound production variable, and a persisting need for cognitive effort while speaking. Conclusions Speech features improved over an extended time, but the recovery trajectories differed, indicating dynamic reorganization of the underlying speech production system. The relationship among speech dimensions should be examined in other cases and in population samples. The combination of quantitative and qualitative analysis methods offers advantages for understanding clinically relevant aspects of recovery.

Over Time

The study of coarticulation—namely, the articulatory modification of a given speech sound arising from coproduction or overlap with neighboring sounds in the speech chain—has attracted the close attention of phonetic researchers for at least the last 60 years. Knowledge about coarticulatory patterns in speech should provide information about the planning mechanisms of consecutive consonants and vowels and the execution of coordinative articulatory structures during the production of those segmental units. Coarticulatory effects involve changes in articulatory displacement over time toward the left (anticipatory) or the right (carryover) of the trigger, and their typology and extent depend on the articulator under investigation (lip, velum, tongue, jaw, larynx) and the articulatory characteristics of the individual consonants and vowels, as well as nonsegmental factors such as speech rate, stress, and language. A challenge for studying coarticulation is that different speakers may use different coarticulatory mechanisms when producing a given phonemic sequence and they also use coarticulatory information differently for phonemic identification in perception. More knowledge about all these research issues should contribute to a deeper understanding of coarticulation deficits in speakers with speech disorders, how the ability to coarticulate develops from childhood to adulthood, and the extent to which the failure to compensate for coarticulatory effects may give rise to sound change.

Purpose Children with Down syndrome (DS) demonstrate speech sound disorders, which impact speech intelligibility in academic and social settings across the life span. The purpose of this technical report is to determine the effects of electropalatographic (EPG) therapy on speech productions for children with DS receiving school-based speech-language therapy services. EPG is a form of visual feedback that displays timing and location of the tongue's contact with the palate during productions of individual phonemes. Method Authors completed a comprehensive literature search to locate articles that investigated the treatment effects of EPG for children with DS. Using the PICO (population, intervention, control, and outcomes) format, we sought in the research to answer “Do children 3–18 years of age with Down syndrome (P), who receive EPG therapy (I) compared to same-age peers with Down syndrome who do not receive EPG therapy (C) show improvement on speech sound production (O)?” Results Three studies met the inclusion criteria and were critically appraised. Two studies were single-subject designs, and one study was a randomized controlled study. Results revealed that EPG therapy improved speech sound production of target phonemes (/s/, /ʃ/, /k/, and /g/) with no transfer to speech intelligibility. Conclusions The results may further the understanding of EPG therapy as a treatment approach, particularly in older individuals with DS receiving school-based speech-language therapy services. Prior to adopting EPG as a treatment approach, clinicians should consider treatment intensity and students' cognitive abilities. Additional research is needed on the long-term effects and generalization of EPG therapy.

Purpose In this study, the authors examined the treatment efficacy of a behavioral speech therapy protocol for adult cochlear implant recipients. Method The authors used a multiple-baseline, across-behaviors and -participants design to examine the effectiveness of a therapy program based on behavioral principles and methods to improve the production of target speech sounds in 3 adults with cochlear implants. The authors included probe items in a baseline protocol to assess generalization of target speech sounds to untrained exemplars. Pretest and posttest scores from the Arizona Articulation Proficiency Scale, Third Revision (Arizona–3; Fudala, 2000) and measurement of speech errors during spontaneous speech were compared, providing additional measures of target behavior generalization. Results The results of this study provided preliminary evidence supporting the overall effectiveness and efficiency of a behavioral speech therapy program in increasing percent correct speech sound production in adult cochlear implant recipients. The generalization of newly trained speech skills to untrained words and to spontaneous speech was demonstrated. Conclusion These preliminary findings support the application of behavioral speech therapy techniques for training speech sound production in adults with cochlear implants. Implications for future research and the development of aural rehabilitation programs for adult cochlear implant recipients are discussed.

Purpose The purpose of this study was to determine the extent to which school-age children with speech sound disorder (SSD) exhibit concomitant reading difficulties and examine the extent to which phonological processing and speech production abilities are associated with increased likelihood of reading risks. Method Data were obtained from 120 kindergarten, first-grade, and second-grade children who were in receipt of school-based speech therapy services. Children were categorized as being “at risk” for reading difficulties if standardized scores on a word decoding measure were 1 SD or more from the mean. The selected predictors of reading risk included children's rapid automatized naming ability, phonological awareness (PA), and accuracy of speech sound production. Results Descriptive results indicated that just over 25% of children receiving school-based speech therapy for an SSD exhibited concomitant deficits in word decoding and that those exhibiting risk at the beginning of the school year were likely to continue to be at risk at the end of the school year. Results from a hierarchical logistic regression suggested that, after accounting for children's age, general language abilities, and socioeconomic status, both PA and speech sound production abilities were significantly associated with the likelihood of being classified as at risk. Conclusions School-age children with SSD are at increased risk for reading difficulties that are likely to persist throughout an academic year. The severity of phonological deficits, reflected by PA and speech output, may be important indicators of subsequent reading problems.

Purpose We conducted a systematic review of the literature regarding adult telepractice services (screening, assessment, and treatment) from approximately 2014 to 2019. Method Thirty-one relevant studies were identified from a literature search, assessed for quality, and reported. Results Included studies illustrated feasibility, efficacy, diagnostic accuracy, and noninferiority of various speech-language pathology services across adult populations, including chronic aphasia, Parkinson's disease, dysphagia, and primary progressive aphasia. Technical aspects of the equipment and software used to deliver services were discussed. Some general themes were noted as areas for future research. Conclusion Overall, results of the review continue to support the use of telepractice as an appropriate service delivery model in speech-language pathology for adults. Strong research designs, including experimental control, across multiple well-described settings are still needed to definitively determine effectiveness of telepractice services.

Defiant Behavior

The Diagnostic and Statistical Manual of Mental Disorders, fifth edition characterizes oppositional defiant disorder (ODD) as reflecting pervasive patterns of irritable mood, defiant behavior, and/or vindictiveness. Youth with autism spectrum disorder (ASD) exhibit high rates of disruptive behaviors commonly associated with ODD, such as noncompliance, irritability, temper tantrums, and mood dysregulation. This chapter reviews the presentation of ODD in individuals with ASD, including current prevalence estimates, proposed etiology, validated assessment methods, and emerging best practices designed to treat challenging behaviors. Although there is a robust literature describing assessment and treatment procedures for disruptive behaviors in individuals with ASD, conceptualizing these hallmark behaviors within the framework of ODD is relatively novel and not without controversy. Discussion thus includes challenges around the applicability of the diagnostic criteria in this population and future research directions that may provide clarity on this issue.

Disorders of development include a range of problems first evidenced in childhood. Although most disorders have their origins in childhood, a few fully express themselves before early adulthood. This chapter describes the nature, assessment, and treatment of the more common disorders that are revealed in a clinically significant way during a child’s developing years. The disorders of development affect a range of functioning, from single skills deficits to more pervasive problems that negatively impact a child’s ability to function. Included is coverage of several disorders usually diagnosed first in infancy, childhood, or adolescence, including attention-deficit hyperactivity disorder, oppositional defiant disorder, conduct disorder, learning disorders, communication and related disorders, pervasive developmental disorders (including autistic disorder and Asperger disorder), and intellectual disabilities. Recommendations for future research on the potential for advancing knowledge regarding spectrums within some of these disorders, as well as recommendations for treatment, are outlined.
