Bilingual infants have astonishing learning capabilities that allow them to learn the sound properties of two different languages in the first year of life. This project investigates how infants discover and distinguish two languages in their speech environment. The research will study how speech sounds infants hear at home guide their discovery of two languages. The project takes an interdisciplinary approach, aiming to collect and analyse bilingual infant-directed speech, test infants’ reliance on sound cues, and use computational models to simulate the learning of two languages from speech.
In the PhD subproject, you will work with Dutch-English bilingual families to collect and analyse a corpus of bilingual infant-directed speech. You will also study bilingual infants’ language discrimination skills using headturn-preference experiments. You will work in an interdisciplinary team with researchers from linguistics, psychology, and artificial intelligence. Assistance from student assistants in data collection and/or processing will be provided, and you will develop academic teaching skills during the project. The project will be carried out at the Institute for Language Sciences (ILS), Utrecht University, the Netherlands.
Your tasks include:
Completion and defence of an article-based PhD thesis within four years (including studying relevant literature and writing articles)
Presenting intermediate research results at workshops and conferences regularly
Publication of peer-reviewed articles in established international journals
Participation in training programmes and expert meetings organised for the project group
