“…Although feedback deficits have a long history of research in children with speech errors (see Figure 1), feedforward deficits have not been well studied in SD. As noted next, emerging studies using different measurement modalities and research designs posit feedforward deficits in CAS (e.g., Iuzzini-Seigel, Hogan, Guarino, & Green, 2015;Terband, Maassen, Guenther, & Brumberg 2014). For the descriptive-behavioral methods of the present study, it seems parsimonious to attribute the lack of groping and self-repairs in participants with SD to deficits in the specification of underlying phonological representations required to motivate such behaviors.…”

Purpose Previous articles in this supplement described rationale for and development of the pause marker (PM), a diagnostic marker of childhood apraxia of speech (CAS), and studies supporting its validity and reliability. The present article assesses the theoretical coherence of the PM with speech processing deficits in CAS. Method PM and other scores were obtained for 264 participants in 6 groups: CAS in idiopathic, neurogenetic, and complex neurodevelopmental disorders; adult-onset apraxia of speech (AAS) consequent to stroke and primary progressive apraxia of speech; and idiopathic speech delay. Results Participants with CAS and AAS had significantly lower scores than typically speaking reference participants and speech delay controls on measures posited to assess representational and transcoding processes. Representational deficits differed between CAS and AAS groups, with support for both underspecified linguistic representations and memory/access deficits in CAS, but for only the latter in AAS. CAS–AAS similarities in the age–sex standardized percentages of occurrence of the most frequent type of inappropriate pauses ( abrupt ) and significant differences in the standardized occurrence of appropriate pauses were consistent with speech processing findings. Conclusions Results support the hypotheses of core representational and transcoding speech processing deficits in CAS and theoretical coherence of the PM's pause-speech elements with these deficits.

“…As described presently, we posit that one "moment" of apraxia-a point in talking when pre-execution commands are not sufficient to continue speaking-includes an inappropriate pause due to transcoding deficits in both representational and motor speech processes. Although origins of such deficits in CAS and AAS differ in pathobiology, we take the position that the two forms of apraxia of speech share generally similar speech processes, with more recent emphasis in the developmental form of apraxia of speech also placed on the processing of feedforward information (e.g., Iuzzini-Seigel et al, 2015;Nijland, Maassen, & van der Meulen, 2003;Preston et al, 2014;Terband et al, 2009;Terband & Maassen, 2010).…”

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.

“…Thus, producing accurate speech sounds together with appropriate suprasegmental elements of speech should be a primary goal for CAS intervention. The core deficit in CAS is in planning and programming speech movements, resulting in increased reliance on external and internal feedback (Iuzzini-Seigel, Hogan, Guarino, & Green, 2015; Preston, Molfese et al, 2014; Terband, Maassen, Guenther, & Brumberg, 2009). Preston et al (2013) hypothesised that enhancing feedback during speech production through the visual domain with ultrasound imaging may enhance error detection and thus allow children with CAS to establish and update the motor commands necessary for proper feed-forward control of speech.…”

Limited acquisition and generalisation of rhotics with ultrasound visual feedback in childhood apraxia

Ultrasound visual feedback of the tongue is one treatment option for individuals with persisting speech sound errors. This study evaluated children's performance during acquisition and generalisation of American English rhotics using ultrasound feedback. Three children aged 10–13 with persisting speech sound errors associated with childhood apraxia of speech (CAS) were treated for 14 one-hour sessions. Two of the participants increased the accuracy of their rhotic production during practice trials within treatment sessions, but none demonstrated generalisation to untreated words. Lack of generalisation may be due to a failure to acquire the target with sufficient accuracy during treatment, or to co-existing linguistic weaknesses that are not addressed in a motor-based treatment. Results suggest a need to refine the intervention procedures for CAS and/or a need to identify appropriate candidates for intervention to optimise learning.
