“…Similarly, van den Bunt et al (2018a) found literate children who read more non-words per minute showed less variation in vowel production. Coughler et al (2021) found increased variability negatively correlated with the amount of compensation in TD children, whereas Ohashi and Ostry (2021) did not find variability correlated with the amount of compensation in children or adults.…”

“…In terms of magnitude and direction of manipulations, eight studies manipulated F1 and F2 values of vowels, and five studies manipulated F1 only. F1 was manipulated in various ways, including: increased by 25% ( Shiller and Rochon, 2014 ; van den Bunt et al, 2018a ), 175 Hz ( Shiller et al, 2010b ), or 340 Hz, or decreased by 230 Hz ( Coughler et al, 2021 ), or manipulated individually so the maximum perturbation represented a change from/ε/to/ae/ ( Ohashi and Ostry, 2021 ). One study manipulated the frequency centroid of fricatives (decreased by 3 semitones; Shiller et al, 2010a ).…”

“…Six studies explored variability of baseline vocal productions related to articulatory control ( Shiller et al, 2010a ; MacDonald et al, 2012 ; van den Bunt et al, 2018a ; van Brenk and Terband, 2020 ; Coughler et al, 2021 ; Ohashi and Ostry, 2021 ). Generally, children showed greater variability compared to adults ( Shiller et al, 2010a ; MacDonald et al, 2012 ; van Brenk and Terband, 2020 ; Ohashi and Ostry, 2021 ).…”

“…Five studies additionally examined perceptual abilities related to articulatory control (i.e., discrimination; Shiller et al, 2010a , b ; Shiller and Rochon, 2014 ; Terband et al, 2014 ; Coughler et al, 2021 ). Coughler et al (2021) found F1 discrimination thresholds did not significantly correlate with percent compensation in the positive or negative condition, or with language scores in TD children or children with a specific deficit in language. Shiller and Rochon (2014) found that productions following an experimental block of relevant (to the formant frequency shift) auditory-perceptual training resulted in enhanced compensatory responses in children.…”

“…Three studies collected articulation information, with two using the Goldman-Fristoe Test of Articulation 2 (GFTA-2; Shiller et al, 2010b ; Daliri et al, 2018 ). Five studies collected receptive and expressive language information with the most common test used being the Clinical Evaluation of Language Fundamentals (CELF; Russo et al, 2008 ; Shiller et al, 2010b ; Coughler et al, 2021 ). Five studies collected information about cognitive abilities with the most common test used being the Wechsler Abbreviated Scale of Intelligence (WASI; Russo et al, 2008 ; Daliri et al, 2018 ; Scheerer et al, 2020b ; Coughler et al, 2021 ).…”

PurposeThe ability to hear ourselves speak has been shown to play an important role in the development and maintenance of fluent and coherent speech. Despite this, little is known about the developing speech motor control system throughout childhood, in particular if and how vocal and articulatory control may differ throughout development. A scoping review was undertaken to identify and describe the full range of studies investigating responses to frequency altered auditory feedback in pediatric populations and their contributions to our understanding of the development of auditory feedback control and sensorimotor learning in childhood and adolescence.MethodRelevant studies were identified through a comprehensive search strategy of six academic databases for studies that included (a) real-time perturbation of frequency in auditory input, (b) an analysis of immediate effects on speech, and (c) participants aged 18 years or younger.ResultsTwenty-three articles met inclusion criteria. Across studies, there was a wide variety of designs, outcomes and measures used. Manipulations included fundamental frequency (9 studies), formant frequency (12), frequency centroid of fricatives (1), and both fundamental and formant frequencies (1). Study designs included contrasts across childhood, between children and adults, and between typical, pediatric clinical and adult populations. Measures primarily explored acoustic properties of speech responses (latency, magnitude, and variability). Some studies additionally examined the association of these acoustic responses with clinical measures (e.g., stuttering severity and reading ability), and neural measures using electrophysiology and magnetic resonance imaging.ConclusionFindings indicated that children above 4 years generally compensated in the opposite direction of the manipulation, however, in several cases not as effectively as adults. Overall, results varied greatly due to the broad range of manipulations and designs used, making generalization challenging. Differences found between age groups in the features of the compensatory vocal responses, latency of responses, vocal variability and perceptual abilities, suggest that maturational changes may be occurring in the speech motor control system, affecting the extent to which auditory feedback is used to modify internal sensorimotor representations. Varied findings suggest vocal control develops prior to articulatory control. Future studies with multiple outcome measures, manipulations, and more expansive age ranges are needed to elucidate findings.

Purpose: Previous studies have found that typically developing (TD) children were able to compensate and adapt to auditory feedback perturbations to a similar or larger degree compared to young adults, while children with speech sound disorder (SSD) were found to produce predominantly following responses. However, large individual differences lie underneath the group-level results. This study investigates possible mechanisms in responses to formant shifts by modeling parameters of feedback and feedforward control of speech production based on behavioral data. Method: SimpleDIVA was used to model an existing dataset of compensation/adaptation behavior to auditory feedback perturbations collected from three groups of Dutch speakers: 50 young adults, twenty-three 4- to 8-year-old children with TD speech, and seven 4- to 8-year-old children with SSD. Between-groups and individual within-group differences in model outcome measures representing auditory and somatosensory feedback control gain and feedforward learning rate were assessed. Results: Notable between-groups and within-group variation was found for all outcome measures. Data modeled for individual speakers yielded model fits with varying reliability. Auditory feedback control gain was negative in children with SSD and positive in both other groups. Somatosensory feedback control gain was negative for both groups of children and marginally negative for adults. Feedforward learning rate measures were highest in the children with TD speech followed by children with SSD, compared to adults. Conclusions: The SimpleDIVA model was able to account for responses to the perturbation of auditory feedback other than corrective, as negative auditory feedback control gains were associated with following responses to vowel shifts. These preliminary findings are suggestive of impaired auditory self-monitoring in children with complex SSD. Possible mechanisms underlying the nature of following responses are discussed.

Purpose This study investigates the development of sensorimotor relationships by examining adaptation to real-time perturbations of auditory feedback. Method Acoustic signals were recorded while preschoolers and adult speakers of Canadian French produced several utterances of the front rounded vowel /ø/ for which F2 was gradually shifted up to a maximum of 40%. Results The findings indicate that, although preschool-aged children produced overall similar responses to the perturbed feedback, they displayed significantly more trial-to-trial variability than adults. Furthermore, whereas the magnitude of the adaptation in adults was positively correlated with the slope of the perceptual categorical function, the amount of adaptation in children was linked to the variability of their productions in the baseline condition. These patterns suggest that the immature motor control observed in children, which contributes to increased variability in their speech production, plays a role in shaping adaptive behavior, as it allows children to explore articulatory/acoustic spaces and learn sensorimotor relationships.
