Evaluating the intelligibility of reverse speech


  Contact person
Melissa BARKAT-DEFRADAS , Fanny MEUNIER

Scientific framework and objectives

The perception of spoken language is a task we daily fulfil and it implies maximal involvement of the cognitive functions. Its intelligibility will vary according to the clarity of the signal and to the brain's ability to process that signal. Reverse speech is regarded as «degraded speech signal in its most drastic form» and it is generally used as a control condition in experiments intended to demonstrate that the human brain has a capacity to process language, for instance. However, previous experiments on the English language have revealed that human's perceptual system is actually able to process reverse speech to a certain extent.

The primary goal of this research is to gauge the ability of the cognitive system to retrieve the phonological and lexical information from sentences with temporally reversed segments.
