“…For recording sufficient numbers of repetitions from the youngest participants, the optimal procedure was found to be repeating after the child's carer. While different elicitation methods have been used in some previous studies of young children's speech production, including those using ultrasound (e.g., Song et al, 2013;Lin and Demuth, 2015;McAllister Byun et al, 2016), in the present study repeating after the carer was the most natural behaviour for young children involved in playing a game together with the carer. All CV syllable tokens by the 3-and 5-year-old participants included in across-group comparison were perceptually correct realisations, which ensured comparability with older children's productions.…”

“…For 3-and 5-year-olds, the ultrasound transducer was instead hand-held by the experimenter (see other ultrasound studies of young children's speech using hand-held recordings, e.g., Song et al, 2013;Lin and Demuth, 2015;Magloughlin, 2016). It was possible to use the same measures in this study for quantifying tongue shape in both stabilised and hand-held ultrasound data, because the measures have previously been shown to produce the same results for these 2 types of data (Zharkova et al, 2015a).…”

Background/Aims: There is growing evidence that coarticulation development is protracted and segment-specific, and yet very little information is available on the changes in the extent of coarticulation across different phonemes throughout childhood. This study describes lingual coarticulatory patterns in 6 age groups of Scottish English-speaking children between 3 and 13 years old. Methods: Vowelon-consonant anticipatory coarticulation was analysed using ultrasound imaging data on tongue shape from 4 consonants that differ in the degree of constraint, i.e., the extent of articulatory demand, on the tongue. Results: Consonant-specific age-related patterns are reported, with consonants that have more demands on the tongue reaching adolescent-like levels of coarticulation in older age groups. Within-speaker variability in tongue shape decreases with increasing age. Conclusion: Reduced coarticulation in the youngest age group may be due to insufficient tongue differentiation. Immature patterns for lingual consonants in 5- to 11-year-olds are explained by the goal of producing the consonant target overriding the goal of coarticulating the consonant with the following vowel.

“…[ 41 ], observing that F2 height increased with age in toddlers acquiring /ɹ/, suggested that some child speakers lack the articulatory skill necessary to lower F3 to adult-like levels, and instead rely on decreased F3—F2 distance to mark the rhotic category. At the same time, young children produce /l/ with an unusually high F2 because of their use of light /l/ instead of the articulatorily more complex dark /l/ (see detailed discussion in Lin and Demuth [ 42 ]). If these production-oriented factors do play a prominent role in determining F2 height in both /ɹ/ and /l/, it could mask any influence of perception, accounting for Idemaru and Holt's [ 40 ] failure to find a systematic relationship between perception and production of the F2 cue.…”

It is known that some adult listeners have more sharply defined perceptual categories than others, and listeners with more precise auditory targets are also more precise in their production of contrasts. There is additionally evidence that children who have not yet mastered production of a contrast show diminished performance on perceptual measures of the same contrast. To date, however, few studies have investigated developmental perception-production relations using the fine-grained measures typical of adult studies. Existing evidence suggests that perception and production can be closely connected in development, but this relationship may break down as perception and articulation mature at different rates. This study evaluated perception and production of the English /r-w/ contrast in 40 typically-developing children aged 9–14. Perceptual sensitivity was measured with a logistic function fitted over responses in a forced-choice identification task using two synthetic 10-step continua from rake to wake. Participants also produced rhotic and non-rhotic words. Across participants, there was a significant correlation between perceptual acuity and rhoticity in production, although this effect was only observed for one of two continua tested. These results provide preliminary evidence compatible with the hypothesis that children with a more refined auditory target for a sound also produce that sound more accurately.

“…As such, our study remains rather descriptive and exploratory, which would require more refined research on the individual cases of exceptions to have a better understanding the interactions among the acoustic, phonetic, phonological, and semantic factors in the learning process in both domains of perception and production. In this regard, studying positional asymmetry and the relationship between perception and production in second language acquisition may also benefit from studies of the same nature in the domain of first language acquisition to have a better understanding of the physiological, articulatory, and perceptual factors as well as language-universal and language-specific properties in phonetic learning (e.g., Lin and Demuth, 2015 ).…”

The present study investigated how syllable structure differences between the first Language (L1) and the second language (L2) affect L2 consonant perception and production at syllable-initial and syllable-final positions. The participants were Mandarin-speaking college students who studied English as a second language. Monosyllabic English words were used in the perception test. Production was recorded from each Chinese subject and rated for accentedness by two native speakers of English. Consistent with previous studies, significant positional asymmetry effects were found across speech sound categories in terms of voicing, place of articulation, and manner of articulation. Furthermore, significant correlations between perception and accentedness ratings were found at the syllable onset position but not for the coda. Many exceptions were also found, which could not be solely accounted for by differences in L1–L2 syllabic structures. The results show a strong effect of language experience at the syllable level, which joins force with acoustic, phonetic, and phonemic properties of individual consonants in influencing positional asymmetry in both domains of L2 segmental perception and production. The complexities and exceptions call for further systematic studies on the interactions between syllable structure universals and native language interference with refined theoretical models to specify the links between perception and production in second language acquisition.

Children's Acquisition of English Onset and Coda /l/: Articulatory Evidence

Abstract: The disparity in the production and perception of children's singleton onset /l/s is linked to both physiological and phonological development. Suggestions are made for future research to tease these factors apart.
