ABSTRACT

This present research analyses the linguistic environmental setting in homes of children under the age of two years from different social groups and looks at the extent to which the speech from other children contributes to shaping that environment. The corpus includes recordings of spontaneous speech from middle-class households in residential urban areas, from lower socioeconomic classes in marginalized urban areas and from impoverished semi-rural areas. Beta regressions were used to estimate whether place of residence could explain the proportion of words from other children that were directed, as well as those that were not directed, towards the child under study. The results showed that children from impoverished semi-rural areas and children from residential areas hear a higher proportion of non-directed words than children from marginalized urban areas. However, when child-directed speech is considered, the two lower socioeconomic groups, urban and semi-rural, hear a higher proportion of words than their residential peers. These results reveal heterogeneity within social groups.

摘要

本研究分析了来自不同社会群体的两岁以下儿童在家中的语言环境，并研究了其他儿童的言语在多大程度上有助于塑造这种环境。语料库包括来自居住城市地区的中产阶级家庭，边缘化城市地区的较低社会经济阶层以及贫困的半农村地区的自发性语音记录。Beta回归用于估计居住地是否可以解释来自其他儿童的单词比例，以及针对非儿童单词的比例。结果表明，与边缘化城市地区的儿童相比，贫困的半农村地区的儿童和居住地区的儿童听到的非定向单词所占的比例更高。但是，考虑到以儿童为导向的语音时，城市和半农村地区这两个较低的社会经济群体所听到的单词比例要高于其居住的同龄人。这些结果揭示了社会群体内部的异质性。
