Research interests and research relations

Speech science is the main scientific interest of our group, the Speech Prosody Studies Group. Under this broad research term, we work mostly with the analysis and modelling of speech prosody (rhythm and intonation), especially the analysis and modelling of duration under a dynamical perspective (coupled oscillators). By studying and automatically generating the utterances' rhythmic structure, our group tries to understand how the stress patterns are formed and structured, and how they vary in different dialects and subjects. Durational contours are considered as gestalten whose building blocks are V-to-V units (unit from a vowel onset to the next one. Cf the p-center litterature). These studies aim at illuminating (1) how rhythm organises speech production, (2) how rhythm guides speech perception, (3) how rhythm is specified in dynamical, abstract terms, (4) how rhythm guides the phonetic implementation, and (5) how a model of coupled oscillators can pace the act of uttering. The relationship with the linguistic rhythm is worked on by analysing and modelling the stress patterns underlying phonological processes such as stress clash, secondary stress, and rhythmic restructuring under speech rate increase.
