– Traitement de la parole et Dyslexie / Dyslexia and Speech Processing

Organisation / Contact: Fanny Meunier (BCL) / Bruno Di Cara (LAPCOS) {Les journées d’étude sont consacrées aux recherches sur l’utilisation de la corrélation inverse pour l’exploration de la perception de la parole.} Abstract Developmental dyslexia is a learning disability characterized primarily by an impaired ability to learn to read, although difficulties are not limited to reading and also affect speech perception. Dyslexia is associated with phonological processing deficits (Blomert, 2011; Del Tufo & Earle, 2020; Ramus et al., 2003; Ramus, 2014; Szenkovits & Ramus, 2005a) that do not only affect the early stages of development. Indeed, research has shown that adults with dyslexia perform poorly on tasks that focus on phonological processing. Nevertheless, these difficulties cannot be accounted for by low IQ level, poor education, or sensory or neurological deficits. As mentioned by Goswami et al. (2002), the phonological deficits in dyslexia may go beyond phonological awareness and phonological representation of words, and underly processes of extraction of suprasegmental information. Moreover, it has been clearly showed that dyslexics perform poorly when speech signal is presented in adverse conditions such as in noise. To explore these issues, the development and exploitation of new methods are fundamental. During this workshop we will discuss new methods of speech synthesis and adaptation of experimental paradigms, evaluating the possibility of testing the processing of different acoustic cues. In particular, we will elaborate on the reverse correlation approach and its relevance for identifying the processing of specific acoustic cues. This revcorr approach consists in introducing random fluctuations into a stimulus and measuring how specific patterns of fluctuations affect recognition. This method allows the investigation of several acoustic dimensions at the same time and the use of test stimuli that are preprocessed (as experimental stimuli) with minimal assumptions.
