Exploiting these advances to empower hearing-impaired and deaf persons with knowledge is a challenge as much as it is a need. Here, we present a part of our work in a national project to develop an environment for automatic translation from Arabic to Saudi Sign Language using 3D animations. One of the main objectives of this project is to develop a bilingual parallel corpus for automatic translation purposes; avatar-based 3D animations are also supposed to be built. These linguistic resources will be used for supporting development of ICT applications for deaf community. Due to the complexity of this task, the corpus is being developed progressively. In this paper, we present a first part of the corpus by working on a specific topic from the Islamic sphere.

The final aim is the prosodic generation for an Arabic Text-To-Speech (TTS) synthesis system. Several authors have already identified on isolated word corpora the effects of speakers, word structure, sound nature and Arabic dialects. In our work hypothesis is to verify these effects for standard Arabic on continuous speech. Firstly a continuous speech corpora is defined and recorded. Then, two automatic tools —the SYNTHAR+ grapheme-phoneme system and the MBROLIGN alignment— are used to label the speech database recorded. Finally several contextually analysis of phonetic unit duration are conducted. Our studies on continuous speech confirm the results already obtained on isolated words –both the consonantal and final pause context effect and the consonantal gemination effect on the vowel duration. We will report also on the effect of the syllabic number on the speech rate. Introduction The curren...

Ces ressources interviennent à la fois pour l’analyse et la synthèse de la langue arabe. Après un rappel du modèle morphologique retenu, les principales règles phonologiques -transformation, suppression, génération- seront décrites. En effet, ces diverses connaissances phonologiques entrent dans le processus de génération automatique de la langue arabe à partir des racines —entités lexicales de bases des dictionnaires— et des schèmes générateurs. Le modèle morphologique basé sur les notions de postfixe(s) + base + antéfixe(s) sera également rappelé. Ensuite le processus de génération sera décrit. La génération d'un mot se compose de différentes étapes clairement identifiées qui utilisent des règles phonologiques pertinentes. Notre travail a consisté à identifier ses règles, à les formaliser et enfin à les associer dan...
