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)

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…

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)

The present investigation examines three hypotheses concerning the development of temporal coordination of consonant clusters in the speech of children at four age levels. Results reveal that five and seven-year-olds can be separated from older children and adults on the basis of absolute duration of consonants. (CHK)

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 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)

The phonotactic development of one child is traced from age 3;9 to 5;3. Data are presented in a table indicating both the child's phonological equivalent of adult consonant sequences and the range distinguished by the child at a given stage. (CHK)

Results are reported of a study of voice onset time characteristics of stops in initial clusters in American English words produced by children and adults. (Author/RM)

Describes English-speaking children's acquisition of voice onset time. The study evaluated two hypotheses, one predicting that children would control the vowel duration contrast earlier than the consonantal one and one predicting that they would control the contrast represented on the segmental level of linguistic description earlier than the…

Compares frequencies of cooccurrences in infant babbling between phonetic and contextual categories to expected frequencies, and considers deviations to be patterns in babbling. Results are provided of an examination of utterances of three Canadian-English and three Parisian-French infants whose babblings were transcribed and categorized according…
