Intonation modeling in cross-linguistic research
This chapter uses the analysis-by-synthesis technique in the framework of the PENTA model to find general patterns of F0 associated with the functions of boundary marking and prominence in two varieties of Portuguese. Both European and Brazilian Portuguese intonation patterns are investigated in two speaking styles, reading and storytelling, within the domain of the phonological word with four speakers per variety. Results show that, despite some individual differences, both varieties mark the terminal boundaries with sharp falling contours and realise non-terminal boundaries with rising contours in storytelling and rising and falling contours in reading. In both speaking styles prominence is realised by falling contours in EP against rising contours in BP reading and both directions in BP storytelling.
