The Hong Kong Bilingual Child Language Corpus , which is reported in 2005 as the world's largest video-linked database of children becoming bilingual, created by Yip, and her husband, Stephen Matthews from The University of Hong Kong — features 170 hours of audio and video files of four families raising their children bilingually in Cantonese and English. The project, which includes transcripts and searchable video and audio segments, took 10 years to compile. This database has already been the data source for several undergraduate and graduate dissertations in Hong Kong, and it is the basis of a book, The "Bilingual Child", written by Yip and Matthews and  published by Cambridge University Press in 2007. The database focuses on children who are bilingual in English and Cantonese and who learned to speak two languages through the one-parent, one-language approach. Using that method, one parent speaks to the child in one language, and the other parent speaks to the child in another.
