Analysis of speech samples from British female adults (N=8) revealed that the subjects increased vocal pitch when addressing young children, but not as much as previously studied North American subjects did. Pitch increases were more commonly observed in free speech than in reading-aloud conditions. (23 references) (Author/CB)

Describe studies in which day-long recordings were made of nine-year-old children's spontaneous speech. Results indicate that: (1) children aged five to 15 speak some 20,000 words of discourse per day in about two to three hours of pure speaking time; (2) they have an active vocabulary of some 3,000 word-form types. (SED)

Provides evidence that in producing voiceless stops in terms of voice-onset-time values, children first overshoot adult values and then only gradually draw back toward adult values. (Author/RL)

Longitudinal studies of the application of a paraphrasing model to 18- to 28-month-olds indicated that mean length of utterance was significantly correlated with realized and paraphrased frequencies of several linguistic items in the subjects' corpora. The model was productive for examining children's corpora of speech and the linguistic…

Data on four infants between the ages of 12 and 20 months were collected to answer two questions about children's communication behavior. (1) Is there a correspondence between communicative intentions expressed in gestures and vocal utterances? If both spring from common organismic tendencies, it should be possible to discern an "indicating"…

Twelve preschool nonstutterers and their mothers were matched with 12 stutterers and their mothers. Analysis of intervention demonstrated that mothers of stutterers talked significantly faster to all children. Stutterers spoke slower than nonstutterers and severe stutterers spoke slower than moderate stutterers. Results revealed an interactive and…

Discusses the variation and stability of mother speech patterns across individuals. Analyzes the functionally coded speech of 11 mothers and provides a typology of mother styles, based on the intentions of mothers to direct or converse with their children. (EKN)

Evidence of semantically based orderings of phrasal coordinations in child speech is explored. Speech samples from two children are analyzed to show that such sequences occur frequently, are internally consistent, and are part of children's active repertoire of referential and expressive acts at an early age. The samples were obtained from one…

Describes adjustments in speech patterns made by two- and three-year-olds when talking to their 14-month-old siblings and compares these changes with those made by mothers addressing their babies. Individual differences between the children indicate two types of influence on the adjustments made--pragmatic and emotional. (EKN)

Maternal directives to 10- and 18-month-old children were analyzed for verbal and nonverbal aspects. The findings emphasize the multimodal nature of mothers' messages and the way language occurs in an action context and not as isolated output. There was no indication that verbal output replaces nonverbal at this age, but the verbal and nonverbal…

A study was conducted to determine the relationship between maternal input to early language learners and language acquisition and to answer the following questions: (1) Does nursery language used with the child change after he begins to talk? (2) Is there reason to believe that the child's speech is influenced by or influences the mother's…

Vowel production of a 14-month-old girl was studied over a 6-month period. Sixty percent of the vowels were produced correctly. A complex pattern of vowel preferences and errors was partially related to prespeech babbling preferences and strongly related to word structure variables (monosyllabic versus disyllabic). (Author/JDD)

Ten mothers and 20 children, aged 5 and 10 years, were examined to determine the time at which velopharyngeal port opening began in /dVn/ syllables and velopharyngeal port closing reached completion in /nVd/ syllables. Adults and children nasalized most vowels in the /dVn/ context and the /nVd context. (Author/JDD)

The ability of young children to communicate at the time they produce their first words was studied, with particular reference to the question of whether children are able to modify their requests depending on the adult's response. The subjects were four children ranging in age from 15 to 18 months; the data were their requests of adults coded…

A study investigated the hypothesis that children are sensitive to functors in language and only omit them due to factors specific to speech production and after having analyzed them as separate morphemes. This hypothesis was tested as an alternative to two existing hypotheses concerning children's selective listening for content words and for…
