Provides a preliminary description of phonological tier development in Cantonese-speaking children. Data were analyzed for word, syllable, onset-rime, skeletal, and segmental tiers. Results suggest a developmental order in acquisition of hierarchical features. (Author/VWL)

One aspect of the phonology of a four-year-old child with Down's syndrome was explored: a phonological constraint ordered his consonants from those produced at the front of the mouth to those produced at the back of the mouth. The value of an analysis that recognizes phonological strategies and larger than phoneme units is discussed. (Author/SEW)

A non-English portion of the universal initial-cluster hierarchy is cognitively represented in English-speaking monolingual children and adolescents. Subjects in an experiment were asked to select frequency of non-English consonant clusters, and they were able to reconstruct the phonological hierarchy. (CK)

One English speaking child's phonological, semantic, and syntactical development from 15 to 21 months old is detailed in order to investigate the development of the mid vowel categories in English as reflected in spontaneous speech production. Prior research on this topic is summarized to reveal certain trends in the development of mid vowels.…

Reports on an experiment, conducted on ten children who misarticulated /s/, and designed to survey the effect of consonant context on misarticulation. Suggests that a context-sensitive model of phonetic performance is needed to account for variation in correct /s/ production. (Author/AM)

This is an investigation of the phonological units used by preschool children. Twenty-four English-speaking children aged 4;0 to 5;0 were given three experimental tasks which investigated their ability to segment initial consonant clusters into phoneme-length units: (1) in a segmentation task they gave the first sound of initial cluster words; (2)…

Reports on two studies on the acquisition by children of the voicing contrast in Mexican Spanish word-initial stops. The first was a longitudinal study. One analysis showed children unable to distinguish between voiced-voiceless stop cognate pairs at age 3;10. A spirantization analysis, however, more clearly revealed the children's phonological…

Reports on an experiment which sought to compare child and adult speech in terms of (1) stop productions evidencing devoicing during consonant closure, and (2) consonant closure evidencing voicing in the case of devoiced stops. (Author/AM)

Describes an unusual phonological pattern exhibited by a child aged two years that involves the production of word-final strident continuants in words whose adult forms contain these features in initial, rather than final, position (e.g., ops for soap). (13 references) (GLR)

Considers the much-debated markedness and structural status of word-initial /s/-sequences in English by examining the development of a 3.5-year-old male who has a phonological disorder. (Author/VWL)

The role of a strategy of reduplication in phonological acquisition and behavior was examined in terms of: (1) the relationship between adoption of this strategy and failure to produce nonreduplicated multisyllabic forms and final consonants, and (2) the role of reduplication in production constraints. (Author/AM)

A detailed analysis of a six-month period in a child's acquisition of phonetic and phonological capacities indicates that the apparent plateau of the second year is a site of intensive language learning, which is not reflected in the growth of vocabulary or mean length of utterance. (Author/EJS)

One-year-olds (N=11) showed no differences in comprehension of words containing consonants that they had never successfully produced (attempted), words with consonants easily produced (in), and words with consonants never before produced or attempted (out). Attempted and out words were less likely to be acquired in production than in words.…

Reports three studies concerning individual differences in children's use of consonants during early phonological development. The findings indicate that these differences fall within a predictable range, that the linguistic environment cannot account for several of them, and that they are partly due to variations in the choice of lexical items.…

Reports on a longitudinal study of the acquisition of the voicing contrast in American English word-initial stop consonants as measured by voice-onset time. The rate and nature of the developmental process are discussed in relation to two competing models of phonological acquisition and two hypotheses regarding the skills being learned. (Author/AM)
