L’étude de la prosodie des langues vocales repose en partie sur la mesure des paramètres de durée, d’intensité et de fréquence sonores. Les langues des signes, quant à elles, empruntent le canal visuogestuel et mobilisent des articulateurs manuels et non manuels (buste, tête, éléments du visage). Notre étude a pour objectif d’établir des outils permettant de comparer, au niveau prosodique, la traduction en français de séquences poétiques et la version originale en langue des signes française (LSF). Nous avons recueilli des données vidéo augmentées de capture de mouvement – qui offrent plusieurs pistes d’exploration des paramètres prosodiques pour la LSF – ainsi que des données audio des traductions en français – qui révèlent les stratégies des interprètes pour interpréter la variation prosodique.

This paper presents the rationale, objectives and advances of an on-going project (the DesPho-APaDy project funded by the French National Agency of Research) which aims to provide a systematic and quantified description of French dysarthric speech, over a large population of patients and three dysarthria types (related to the parkinson's disease, the Amyotrophic Lateral Sclerosis disease, and a pure cerebellar alteration). The two French corpora of dysarthric patients, from which the speech data have been selected for analysis purposes, are firstly described. Secondly, this paper discusses and outlines the requirement of a structured and organized computerized platform in order to store, organize and make accessible (for selected and protected usage) dysarthric speech corpora and associated patients’ clinical information (mostly disseminated in different locations: labs, hospitals, …). The design of both a computer database and a multi-field query interface is proposed for the clinical context. Finally, advances of the project related to the selection of the population used for the dysarthria analysis, the preprocessing of the speech files, their orthographic transcription and their automatic alignment are also presented.
