“…Variations in coarticulation degree are represented along a continuum from large coarticulatory overlap between consonantal and vocalic gestures (i.e., more holistic organization) to instances involving coarticulatory resistance from the consonant (i.e., more segmental organization).

“…Participants' productions that did not match the model speaker's word were discarded from further analysis, except for those of 3-year-old children. Given that kinematic data from young children are highly relevant for clinical outcomes but still scarce (five 2-year-olds: Song et al, 2013; seventeen 3-year-olds: Noiray et al, 2018Noiray et al, , 2013, we opted for more flexibility in order to maximize quantification of anticipatory processes. We therefore used as many correctly produced CV syllables as possible, so words were kept as long as C 1 V corresponded to the model speaker and C 2 did not differ in place of articulation from the model word (e.g., /aɪnə ba:tə/ was kept for model /aɪnə ba:də/).…”

Purpose: This study examines the temporal organization of vocalic anticipation in German children from 3 to 7 years of age and adults. The main objective was to test for nonlinear processes in vocalic anticipation, which may result from the interaction between lingual gestural goals for individual vowels and those for their neighbors over time.Method: The technique of ultrasound imaging was employed to record tongue movement at 5 time points throughout short utterances of the form V1#CV2. Vocalic anticipation was examined with generalized additive modeling, an analytical approach allowing for the estimation of both linear and nonlinear influences on anticipatory processes. Results: Both adults and children exhibit nonlinear patterns of vocalic anticipation over time with the degree and extent of vocalic anticipation varying as a function of the individual consonants and vowels assembled. However, noticeable developmental discrepancies were found with vocalic anticipation being present earlier in children's utterances at 3-5 years of age in comparison to adults and, to some extent, 7-year-old children.Conclusions: A developmental transition towards more segmentally-specified coarticulatory organizations seems to occur from kindergarten to primary school to adulthood. In adults, nonlinear anticipatory patterns over time suggest a strong differentiation between the gestural goals for consecutive segments. In children, this differentiation is not yet mature: Vowels show greater prominence over time and seem activated more in phase with those of previous segments relative to adults.

“…Evidence for more coarticulation in children than in adults has been reported by some studies [9,[14][15][16][17], whereas evidence for less coarticulation in children has been reported by others [11,[18][19][20][21][22], and evidence for the same amount of coarticulation has been reported by some others [6,[23][24][25]. Interestingly, a recent study reported that German speaking children and adults had similar trends in the variation of the degree of coarticulation across consonants [26].…”

“…Concerning the V 1 CV 2 sequences, two metrics were used to compare tongue position and shape for each V 1 vowel (/a/ and /ε/) across V 2 contexts. First, based on previous work focusing on the development of anticipatory coarticulation ( [26], for instance), for each tongue contour, the (x,y) coordinates of the highest point of the contour were extracted. These values were z-scored in order to cancel the influence of vocal tract size differences between adults and children.…”

This study aimed to evaluate the role of motor control immaturity in the speech production characteristics of 4-year-old children, compared to adults. Specifically, two indices were examined: trial-to-trial variability, which is assumed to be linked to motor control accuracy, and anticipatory extra-syllabic vowel-to-vowel coarticulation, which is assumed to be linked to the comprehensiveness, maturity and efficiency of sensorimotor representations in the central nervous system. Method Acoustic and articulatory (ultrasound) data were recorded for 20 children and 10 adults, all native speakers of Canadian French, during the production of isolated vowels and vowelconsonant-vowel (V 1-C-V 2) sequences. Trial-to-trial variability was measured in isolated vowels. Extra-syllabic anticipatory coarticulation was assessed in V 1-C-V 2 sequences by measuring the patterns of variability of V 1 associated with variations in V 2. Acoustic data were reported for all subjects and articulatory data, for a subset of 6 children and 2 adults. Results Trial-to-trial variability was significantly larger in children. Systematic and significant anticipation of V 2 in V 1 was always found in adults, but was rare in children. Significant anticipation was observed in children only when V 1 was /a/, and only along the antero-posterior dimension, with a much smaller magnitude than in adults. A closer analysis of individual speakers revealed that some children showed adult-like anticipation along this dimension, whereas the majority did not. Conclusion The larger trial-to-trial variability and the lack of anticipatory behavior in most children-two phenomena that have been observed in several non-speech motor tasks-support the

“…The many advantages of ultrasound scanners (e.g., mobility, affordability, and non-invasiveness) have made it an increasingly popular tool in the field of speech production. Ultrasound is currently the most fruitful way to obtain quantitative lingual data from young children (e.g., Noiray et al, 2018;Noiray et al, 2013), sensitive populations (e.g., in participants with developmental apraxia of speech: Nijland et al, 2002), and in speakers living in remote areas: Whalen et al, 2011). However, ultrasound data present methodological challenges primarily due to the absence of physiological reference points.…”

In previous research, mutual information (MI) was employed to quantify the physical information shared between consecutive phonological segments, based on electromagnetic articulography data. In this study, MI is extended to quantifying coarticulatory resistance (CR) versus overlap in German using ultrasound imaging. Two measurements are tested as input to MI: (1) the highest point on the tongue body and (2) the first coefficient of the discrete Fourier transform (DFT) of the whole tongue contour. Both measures are used to examine changes in coarticulation between two time points during the syllable span: the consonant midpoint and the vowel onset. Results corroborate previous findings reporting differences in coarticulatory overlap in German and across languages. Further, results suggest that MI used with the highest point on the tongue body captures distinctions related both to place and manner of articulation, while the first DFT coefficient does not provide any additional information regarding global (whole tongue) as opposed to local (individual articulator) aspects of CR. However, both methods capture temporal distinctions in coarticulatory resistance between the two time points. Results are discussed with respect to the potential of MI measure to provide a way of unifying coarticulation quantification methods across data collection techniques.
