“…Clinical studies might observe how treatment directed at the deletions/substitutions of SD/PSD versus treatment targeting the common and uncommon speech sound distortions of SE/PSE might increase intelligibility. Greater sensitivity to spatiotemporal differences in distortions (i.e., differences in place, manner, voicing, duration, and force) using contemporary signal processing modalities could be informative for explication and increased clinical efficacy in treatment designs (e.g., Hitchcock, McAllister Byun, Swartz, & Lazarus, 2017; McAllister & Ballard, 2018; McAllister Byun et al, 2017; McAllister Byun & Hitchcock, 2012; Preston, Leece, & Maas, 2016).…”

Although there is substantial rationale for a motor component in the speech of persons with Down syndrome (DS), there presently are no published estimates of the prevalence of subtypes of motor speech disorders in DS. The goal of this research is to provide initial estimates of the prevalence of types of speech disorders and motor speech disorders in adolescents with DS. Conversational speech samples from a convenience sample of 45 adolescents with DS, ages 10 to 20 years old, were analysed using perceptual and acoustic methods and measures in the Speech Disorders Classification System (SDCS). The SDCS cross-classified participants into five mutually exclusive speech classifications and five mutually exclusive motor speech classifications. For participants meeting criteria for Childhood Dysarthria or for Childhood Dysarthria concurrent with Childhood Apraxia of Speech, the SDCS provided information on participants’ percentile status on five subtypes of dysarthria. A total of 97.8% of participants met SDCS criteria for Speech Disorders and 97.8% met criteria for Motor Speech Disorders, including Childhood Dysarthria (37.8%), Speech Motor Delay (26.7%), Childhood Dysarthria and Childhood Apraxia of Speech (22.2%), and Childhood Apraxia of Speech (11.1%). Ataxia was the most prevalent dysarthria subtype. Nearly all participants with DS in the present sample had some type of speech and motor speech disorder, with implications for theory, assessment, prediction, and treatment. Specific to treatment, the present findings are interpreted as support for motor speech disorders as a primary explanatory construct to guide the selection and sequencing of treatment targets for persons with DS.

“…Alternative treatment approaches that can better address the needs of this population clearly merit exploration. Recent research suggests that speech therapy using visual biofeedback (VBF) can provide an alternative approach to the remediation of persistent speech sound disorders in a number of clinical populations (Hitchcock et al 2017). Research exploring VBF with individuals with DS is limited.…”

“…The external representation of an accurate speech target facilitates correction of an error pattern instead of relying on internal selfperception. These effects have been documented across various biofeedback technologies, including acoustic biofeedback, in which the client views a computer-generated acoustic representation (e.g., LPC spectrum 5,18 or spectrogram 1 ) of his/her speech; ultrasound biofeedback, 7,19 in which an ultrasound probe held beneath the chin generates an image of the client's tongue during speech; electropalatography, 20,21 which uses a pseudopalate to register and display areas of contact between the client's tongue and palate; and electromagnetic articulography, in which an animated 3D tongue avatar moves in real time with the client's own tongue. 22,23 The benefit of incorporating visual biofeedback as a dynamic, visual teaching modality is rapidly gaining recognition in the field of speech-language pathology.…”

“…For example, the least optimal biofeedback type for rhotic errors may be EPG, which shows information about lateral bracing of the tongue but yields little information about other more salient features of rhotic articulation. 21 Given the preliminary nature of this review and the disproportionate number of ultrasound participants compared with visual-acoustic and EPG, identification of an interaction suggesting a preferred biofeedback type was considered premature.…”

Speech Sound Disorder and Visual Biofeedback Intervention: A Preliminary Investigation of Treatment Intensity

A growing body of research suggests that cases of speech sound errors that have not responded to previous intervention can sometimes be eliminated through speech therapy incorporating visual biofeedback. Aside from considerations related to the specific biofeedback type, acquisition and generalization of a motor plan may be linked to treatment intensity. Several researchers have raised the possibility that inadequate dosage levels may present a significant barrier to success. Thus, the current study aimed to assess the relationship between treatment intensity and treatment outcomes. Twenty-nine articles reporting the use of visual biofeedback intervention for speech sound disorder were identified and coded for treatment intensity using the cumulative intervention index and outcomes using mean level difference scores. Findings reveal small but significant relationships between measures of treatment intensity and efficacy, which should be interpreted with caution given the preliminary nature of this review. Further research in this area is necessary, as inconsistencies in reporting intensity and outcomes across studies underscore the need for more systematic terminology and reporting methods.
