I work on the cognitive processing of speech and language with focus on speech sound learning and category formation in adults and infants. I am interested in all areas of laboratory phonology and phonetics in general. My current projects aim to describe the development al trajectory of various types of vowel contrasts in Czech-learning infants, assessing the effects of pre-natal exposure in newborns and the effects of talker accent on speech sound learning in older infants. I use behavioural (e.g. looking paradigms), neurophysiological (ERPs) and computational methods (neural networks).

Our research features in a video on baby language, morning TV show and news report on native and second language speech learning.
