Biography.
Virginia Yip received her B.A. in linguistics at the University of Texas at Austin and, in 1989, her Ph.D. from the University of Southern California. 
She is the author of "Interlanguage and Learnability: from Chinese to English" (Benjamins) and co-author of a series of works on Cantonese grammar published by Routledge: "Cantonese: A Comprehensive Grammar" (which has been translated into Japanese), "Basic Cantonese," and "Intermediate Cantonese".
She and her team have created the Hong Kong Bilingual Child Language Corpus, the first longitudinal bilingual corpus in which Cantonese is represented along with English, and the largest multimedia bilingual corpus in the Child Language Data Exchange System (CHILDES) based at Carnegie Mellon University.
Yip is married to linguist Stephen Matthews from the University of Hong Kong. They have three bilingual children: a son and two daughters.
The Hong Kong Bilingual Child Language Corpus.
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.
