The contribution of visual articulatory gestures and orthography to speech processing: Evidence from novel word learning.

Auditory speech appears to be linked to visual articulatory gestures and orthography through different mechanisms. Yet, both types of visual information have a strong influence on speech processing. The present study directly compared their contributions to speech processing using a novel word learning paradigm.

Orthography and second language word learning: Moving beyond "friend or foe?".

French participants learned English pseudowords either with the orthographic form displayed under the corresponding picture (Audio-Ortho) or without (Audio). In a naming task, pseudowords learned in the Audio-Ortho condition were produced faster and with fewer errors, providing a first piece of evidence that orthographic information facilitates the learning and on-line retrieval of productive vocabulary in a second language. Formant analyses, however, showed that productions from the Audio-Ortho condition were more French-like (i.

Dysarthria in individuals with Parkinson's disease: a protocol for a binational, cross-sectional, case-controlled study in French and European Portuguese (FraLusoPark).

Introduction: Individuals with Parkinson's disease (PD) have to deal with several aspects of voice and speech decline and thus alteration of communication ability during the course of the disease. Among these communication impairments, 3 major challenges include: (1) dysarthria, consisting of orofacial motor dysfunction and dysprosody, which is linked to the neurodegenerative processes; (2) effects of the pharmacological treatment, which vary according to the disease stage; and (3) particular speech modifications that may be language-specific, that is, dependent on the language spoken by the patients. The main objective of the FraLusoPark project is to provide a thorough evaluation of changes in PD speech as a result of pharmacological treatment and disease duration in 2 different languages (French vs European Portuguese).

An intonational cue to word segmentation in phonemically identical sequences.

We investigated the use of language-specific intonational cues to word segmentation in French. Participants listened to phonemically identical sequences such as /selafi/, C'est la fiche/l'affiche "It's the sheet/poster." We modified the f0 of the first vowel /a/ of the natural consonant-initial production la fiche, so that it was equal to that of the natural vowel-initial production l'affiche (resynth-consonant-equal condition), higher (resynth-consonant-higher condition), or lower (resynth-consonant-lower condition).
