Paul Boersma
University of Amsterdam
Paul Boersma received an MSc in physics from the University of Nijmegen in 1988 and a PhD in linguistics from the University of Amsterdam in 1998. Since 2005 he has been Professor of Phonetic Sciences at the University of Amsterdam.
His research focuses on modelling and simulating the acquisition, evolution and typology of the production and comprehension of phonology and phonetics. For this he developed a bidirectional model of phonology and phonetics (BiPhon) in which the speaker and listener travel the same morphological, phonological and phonetic levels of representation, which are connected by symmetric constraints that are weighted or ranked, or by symmetric neural network connections.
His further research involves the history of the Franconian tone systems. Boersma is also the designer and main author (with David Weenink) of Praat, the world’s most used computer program for the analysis and manipulation of speech.
