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)

Analysis of longitudinal data from four Mexican-American children to explore two aspects of the acquisition of Spanish word stress indicates that children approach such learning unbiased toward any particular stress type. Children's attention to phonetic or semantic aspects of normatively unstressed syllables leads them to shift stress to that…

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)

Distinctive feature specification and representation in phonological acquisition are examined in 30 children in the context of underspecification theory. Three questions were addressed: which features do children use to categorize segmental information; do the defining features of a category shift as the phonological system advances; and which…

Fourteen two-year-olds were presented with minimal word pairs in a new and efficient experimental perception paradigm. Data provide a view of relative difficulty of various minimal phonological contrasts for children. (CHK)

Discusses the possibility that early linguistic experience affects infant speech perception and that this effect may be of practical consequence in later language learning. (EKN)

Examination of the phonological acquisition of a young girl whose parents spoke two Cantonese dialects indicated that she acquired neither parents' dialect, supporting the claim that children use all available input in acquiring language rather than limiting themselves to a primary language model.

Presents details of the linguistic modification in speech to children in the Mayan language, Quiche. Evaluates 17 features commonly cited for speech to children and notes seven additional features for Quiche: whispering, initial-syllable deletion, BT formed for verbs, a verbal suffix, more fixed word order, more imperatives, and a special…

Examines the relationship between phonetic substitution patterns in child speech and sound change patterns in dialects of adult language, basing an explanation of these phenomena on acoustic data and language universals. (AM)

Focuses on the influence of language specific properties in the acquisition of locative expressions. Some of the claims from literature on the acquisition of locative expressions are discussed and data from the acquisition of Warlpiri are presented and discussed in terms of these claims.

Analysis of the babbling of five infants indicated that between 14 and 40 percent of utterances recurred in particular contexts with a greater than expected frequency, suggesting that babbling is not entirely random but contains consistent sound-meaning relationships that are not adult-modeled. (Author/CB)

Examination of the transition to purposive use of intonation with single words for two infants revealed that both clearly used rising tones to ask questions by 1.5 years of age and demonstrated widespread and gradual grammatical use of intonation. (Author/CB)

Cross-cultural investigation of the influence of target-language in infant babbling analyzed 1047 vowels produced by 10-month-olds (N=20) from French, English, Cantonese, and Arabic language backgrounds. Results revealed differences among infants across language backgrounds, with the differences paralleling those found in adult speech in the…

Phonetic and phonological analysis of spontaneous speech of six 2-year-old monolingual Puerto Rican Spanish-learning children revealed several sound usage patterns similar to those found in English and other language-learning children, supporting the claim that certain universal patterns exist in phonological development.
