Sónia Frota is a Professor of Experimental Linguistics, the Director of the Lisbon Baby Lab, the Scientific Coordinator for the Center of Linguistics at the University of Lisbon, and the Vice-President of the International Phonetics Association. Sónia’s research and publications focus on prosody in language, and on early speech perception and language development in typical and atypical populations. Her work seeks to understand the properties of prosodic systems (phrasing, intonation, and rhythm), the extent to which they vary across and within languages, and how they are acquired by infants and help to bootstrap the learning of language. With her colleagues at the Lisbon Baby Lab, she has developed a number of resources and tools for the screening of early language development, including the acquisition of prosody.
