Applies two fundamental principles of optimalist theory to yield predictions about cluster reduction patterns. (Author/VWL)

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)…

Acoustic studies have shown that phonetic context can have substantial effects on the cues associated with a given speech sound. The present study investigates whether or not modifications in the acoustic correlates of initial stops and fricatives due to the following vowel can affect phonemic decision processes. In the first of two experiments,…

The pronunciation of stop consonants in consonant-vowel-consonant words by 45 preschool children (15 with speech disorders) was evaluated. In the speech-disordered group, errors in initial position differed from those in final position. Voicing errors occurred most frequently in initial position, and glottal stop realizations in final position.…

Describes vocalizations of five 13-month-old infants. Data are reported on syllable shape, vowel-like and consonant-like production in context and time, periodic utterances, complex babbling sequences, recurrent phonetic forms, fundamental frequency, and intonation types. Results are consistent with data from other studies and support theory of…

Describes two experiments which examined the way in which kindergarteners, first graders, and adults spell syllables like /spa/,/sta/, and /ska/. The proportion of voiced spellings was found to decrease with reading level. The nonstandard spellings were fairly prevalent among children, but almost nonexistent among adults. (SED)

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…

This study examined perceptual and articulatory confusions among the fricatives /f, v, s, z/ and voiced and unvoiced "th" in preschool children. (These phonemes are among the most difficult for children to articulate.) Seventeen children from 3.3-5.1 years of age were tested on syllables formed by taking all combinations of the six…

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)
