Research thematics:

My research domain is the study of the auditory categorisation. The hypothesis is that we organize our perception by categorisation to teach and to organise our sound world. This categorisation is dynamic (it is not fixed by a training, but varies according to needs), cognitive driven, and the objective of action depends very directly on task, and of action goal.

My studies concern three types of auditory stimuli: speech, music and environmental sounds. They are principally based on the theory of prototype and typicality, developed by Rosch (1976) and taken back in France by Dubois (1991). With objective to answer this hypothesis, I collaborate on some studies in several domains:

  • studies with non-deaf and deaf people, children and adults, with cochlear implant, to understand their perception of environmental sounds.
  • studies to simulate specific deafness (for example presbyacousy) to preset auditory aids.
  • studies on the understanding (and the diference with intelligibility) of speech, and its applications in industrial domain.

The experimentation using the prototype categorization theory require experimental paradigms ad hoc. It is for it that I develop since 2003 experimental software TCL-LABX (

The research in audition also passes by adapted technological facilities, that is why I have the responsability of the "Cognition, Behaviour and Use" facilities (CCU) including a set in audition (audiometric cabin).
