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…

A study was conducted of the development of consonant clusters in the phonology of a native English-speaking child. His progress was studied over a year and a half period, in three one-month segments. His speech was recorded by tape and transcribed. Techniques used to elicit consonant clusters included real word imitation, imitation of nonsense…

Luo-speaking children in Kenya responded to a test using nonce forms in morphophonology. Morphophonological processes in the acquisition of Luo plurals and possessives presented different degrees of difficulty for the subjects, with the type of morphophonological alteration in a language likely to affect the rate and order of acquisition.…

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.

Previous studies have defined the earliest stage of child language to be the stage at which an uninitiated speaker of adult language can understand sentences spoken by the child. Upon the examination of the language of one child, aged 1 year and 7 months, it became evident that she could talk, even though it was equally evident that she didn't use…

The phonologies of three English-speaking children at approximately two years of age are examined. Two of the analyses are based on published studies; the third is based on observations and recordings made by the author. Summary statements on phonemic inventories and on correspondences with the adult model are presented. For the third case, fairly…

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…

This study of 10 intonation curves, representative of speech patterns in French, entails spectrographic analysis of the variations of fundamental frequency, intensity, and duration. Discriminatory auditory tests are based on semantic oppositions caused by single intonation contrasts. The seven distinctive classes called "intonemes" are: (1) minor…

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. (Author/CB)

Examined the pattern of deletion of final "/t/" and "/d/" in word final consonant clusters in 3- and 4-year-old children (n=16) and their degree of mastery of phonological and grammatical constraints. Results indicate that children as young as three had mastered the phonological constraints on (-t, d) deletion and that the…

Tests the universality hypothesis of language acquisition by asking young monolingual English and Japanese children to verify true affirmatives, false affirmatives, false negatives, and true negatives. The hypothesis was not supported in the case of Japanese-speaking children. A theory of cross-linguistic language acquisition is proposed.…

This document contains 21 reports on speech research relating to the following areas: phonology, speech development, speech perception, phonetics, short-term memory of tactile stimuli, reading, linguistic and paralinguistic interchange, computer processing of EMG (electromyographic) signals, pitch determination by adaptive autocorrelation method,…
