The variable of “linguistic inputs” plays a critical role in language acquisition and language development. The present study examined this research question by conducting a detailed day-by-day language analysis on all the linguistic inputs perceived by a group of Chinese-English bilingual infants for three months. Through language recording and analysis, some estimates are obtained of the linguistic properties of the words as well as the language structures perceived by the infants. The preliminary findings provide a solid and realistic picture of the different categories and properties of the linguistic inputs spoken to and around the infants. Important implications from the present set of data for the study of bilingual language development will be discussed.
