Research topics developed by the group
By using diverse experimental settings we explore the relations between acoustic- and articulatory-prosodic parameters to describe the prosody of L1 and L2 speech. We have been using devices such as Resp Track (for capturing chest and belly expansions) and Marrys cap (for capturing jaw movement) in our investigations. Prosodic modelling is done mostly in the domains of rhythm and intonation couched in dynamical systems theory.
Acoustic and articulatory parameters are used to characterize the segmental and suprasegmental phonetic inventory of Brazilian Portuguese, covering aspects such as vowel and consonant production, voice quality, and the interaction between phonation and articulation across different speaker groups and regional varieties.
Acoustic- and articulatory-prosodic parameters in the dimensions of melody, timing, intensity and voice quality are used to describe atypical speech of some pathological conditions (Parkinson's disease, dysarthria).
Acoustic- and articulatory-prosodic parameters in the dimensions of melody, timing, intensity and voice quality are used to describe the prosodic phonetics of Brazilian Portuguese in diverse speaking styles such as poetry declamation, speech of professionals of voice, the speech of teachers and journalists in radio and TV.
Acoustic- and articulatory-prosodic parameters in the dimensions of melody, timing, intensity and voice quality are used to map the variability of prosody within and across speakers in different experimental settings.
Acoustic and articulatory-prosodic parameters in the dimensions of melody, timing, intensity and voice quality are used to describe the prosodic phonetics of Brazilian Portuguese in distinct forensic-simulated conditions.
