Intelligibility of Reverse Speech in French: a Perceptual Study

We ran an experiment focusing on cognitive implication of reverse speech segments. Nine durations of reverse speech plus a nondistorted control condition have been considered (varying between 20 ms and 180 ms) in order to test the pattern of intelligibility degradation in French. We observed an overall strong negative correlation between the degree of intelligibility and the size of reverse speech windows. These results appear to be very comparable to those obtained in English by Greenberg and Arai (2001), at least on the slope of intelligibility performance decrease. However, intelligibility loss in French is delayed by 20 ms. Apart from con- firming the cognitive ability to restore reverse speech up to a certain point, our study revealed differences that could be interpreted as language specific.
