Scientific framework and objectives

The oral mode of human language, viz. speech, possesses particular temporal and spectral acoustic features. Determining the specific brain networks involved in language processing constitutes a major concern in studies dealing with human cognition. This context has favoured the emergence of the belief that human's brain is predisposed to process the 'primitive' components of language. We may indeed wonder if the brain has specialized networks of areas for the processing of human language and whether these neural chains respond only and/or specifically to human's voice and/or to its characteristics.

In order to explore the neural mechanisms and markers involved in speech perception, we are studying the effect of reverse speech on the cognitive processing of speech, and more particularly, what brain mechanisms are associated with loss of intelligibility and cognitive restoration.
