Research Area

We investigate how young infants become interested in speech that surround them, and learn to be the speaker of that language. In particular, we focus on the role of 'prosody' (i.e., intonation, rhythm and other suprasegmental characteristics of the speech) in language acquisition. We study how infants become attuned to the prosodic characteristics of their ambient language, and how acquiring it would affect other domains of language development.
