Aims: Although IDS is typically described as slower than adult-directed speech (ADS), potential impacts of slower speech on language development have not been examined. We explored whether IDS speech rates in 42 mother-infant dyads at four time periods predicted children's language outcomes at two years. Method: We correlated IDS speech rate with…

In the period between sole use of single words and majority use of multiword utterances, children draw from their existing productive capability and conversational input to facilitate the eventual outcome of majority use of multiword utterances. During this period, children use word combinations that are not yet mature multiword utterances, termed…

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)

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)

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 undertaken to separate elements of maternal speech heavily influenced by the children's language levels from those representing the mothers' consistent style or strategy for "teaching" language. A striking similarity was found between speech mothers used with their daughters and that used with their daughters' friends. (MSE)

Words artificially isolated from 12 parents' speech to their children aged 1;10-3;0 were significantly less intelligible to adult listeners than words originally spoken to an adult. While parents did not adjust the clarity of words, their speech was more redundant in anticipation of the children's comprehension. Research implications are…
