Perception Control Multimodality Dynamics of Speech

Multidisciplinarity in cognitives sciences/language sciences

The heart of the PCMD team's research deals with studying the relationship between oral language and the cognitive processes that ensure its functioning. The cohesion of the team is based on the disciplinary complementarity of its members (affiliated to sections 07 (Information Sciences), 26 (Brain, Cognition and Behavior) and 34 (Language Sciences) of the French National Center of Scientific Research (CNRS); to sections 07 (Language Sciences), 16 (Psychology and Ergonomy), and 61 (Computing and Signal treatment) of the National Council of French Universities (CNU); and to Doctoral Schools EDISCE and LLSH at the Université Grenoble Alpes) around a common theoretical framework in cognitive sciences and language sciences, granting us autonomy for experimentation, data processing and modeling.

Research topics

A characteristic of the team is to study speech as anchored in the reality of the body that produces it, and located in a context of interaction with an interlocutor. All the projects developed in the team share this question: how anatomical/physiological, neurophysiological, linguistic and situational constraints affect or even structure the cognitive processes of production and perception of oral language and spoken communication in the broad sense, not only in adults, but also during development in children, and in children and adults with speech disorders (clinical phonetics).

These questions are addressed by combining experimental methods (behavioral recording including Babylab, motion capture, EMG, TMS, sensory disturbances, brain imaging, EEG, MEG, fMRI) with computational modeling (signal processing, control theory, Bayesian models , AI).

Research topics and projects of the team can be grouped in three 3 axes :

1. Sensorimotor Control of Speech
2. Cognitive Processes of Speech Encoding/Decoding
3. Communication in interaction

You will find below the most recent projects lead by members of the team along these three axes (with the mention of the members implied, their collaborators and the main funding agencies):
