We describe a corpus of speech taking place between 30 Korean mother-child pairs, divided in three groups of Prelexical ( = 0;08), Early-Lexical ( = 1;02), and Advanced-Lexical ( = 2;03). In addition to the child-directed speech (CDS), this corpus includes two different formalities of adult-directed speech (ADS), i.e., family-directed ADS (ADS_Fam) and experimenter-directed ADS (ADS_Exp). Our analysis of the MLU in CDS, family-, and experimenter-directed ADS found significant differences between CDS and ADS_Fam, and between ADS_Fam and ADS_Exp, but not between CDS and ADS_Exp. Our finding suggests that researchers should pay more attention to controlling the level of formality in CDS and ADS when comparing the two registers for their speech characteristics. The corpus was transcribed in the CHAT format of the CHILDES system, so users can easily extract data related to verbal behavior in the mother-child interaction using the CLAN program of CHILDES.
我们描述了一个由30对韩国母婴对话组成的语料库，这些对话被分为三个组：前词汇组（=0;08）、早期词汇组（=1;02）和高级词汇组（=2;03）。除了儿童导向言语（CDS）外，该语料库还包括两种不同形式的成人导向言语（ADS），即家庭导向成人言语（ADS_Fam）和实验者导向成人言语（ADS_Exp）。我们对CDS、家庭导向和实验者导向的ADS中的平均语句长度（MLU）进行分析后发现，CDS与ADS_Fam之间、ADS_Fam与ADS_Exp之间存在显著差异，但CDS与ADS_Exp之间没有差异。我们的研究结果表明，在比较两种语域的言语特征时，研究人员应更加注意控制CDS和ADS中的正式程度。该语料库采用儿童语言数据交换系统（CHILDES）的CHAT格式进行转录，因此用户可以使用CHILDES的CLAN程序轻松提取与母婴互动中言语行为相关的数据。
