This work presents a hybrid approach to sign language synthesis. This approach allows hand-tuning the phonetic description of the signs, focusing on the time aspect of the sign. Therefore, we keep the capacity of performing morphonological operations, like the notation-based approaches and improving the synthetic signing performance, like the hand-tuned animations approach.Our approach simplifies input message description using a new high level notation and storing sign phonetic descriptions in a relational database. The relational database allows more flexible sign phonetic descriptions; it also allows describing sign timing and the synchronization between sign phonemes. The new notation, named HLSML, focuses on message description; it is a gloss-based notation. HLSML introduces several tags that allow modifying the signs in the message defining dialect and mood variations (both defined in the relational database) and message timing (transition durations and pauses). We also propose a new avatar design that simplifies the development of the synthesizer and avoids any interference in the independence of the sign language phonemes during the animation.The obtained results show an increase of the sign recognition rate compared to other approaches. This improvement is based on the active role that the sign language experts have in the description of signs, allowed by the flexibility of the sign storage approach. The approach will simplify the description of synthesizable signed messages so the creation of multimedia signed contents will be easier.

“…To achieve device independence in gesture recognition, Yan [13] also prescribes mapping the gestural observations to higher level predicates that are often inspired by linguistics notations. Modeling character animations cognitively adopts similar notions of higher level gestural predicates ( [14][15][16]). Scalability in perception and in the level of details (local and global changes) is necessary to disambiguate signs and their meanings.…”

Abstract. The study of sign languages attempts to create a coherent model that binds the expressive nature of signs conveyed in gestures to a linguistic framework. Gesture modelling offers an alternative that provides device independence, scalability and flexibility for the annotation and modelling of linguistic phenomena. This paper presents the requirements and initial experiments to build an input method editor for sign languages. The objective is to design interfaces backed up by computational methods that can infer and use linguistic guidance to model sign language gestures. This in turn produces a linguistically annotated corpus of gesture animations.
