The LENA recording system is a reliable tool for estimating word counts, even for bilingual input.
As a group, the English‐French bilingual infants segmented in both of their native languages. However, exploratory analyses suggest that exposure to language mixing may play a role in bilingual infants’ segmentation skills.
These findings show that bilingual infants have a distinct challenge in segmenting words in both their native languages. Further research exploring early word segmentation will advance our understanding of bilingual acquisition and expand our fundamental knowledge of language and cognitive development.
