 Sinehub is creating a digital platform hosting the content of the project, cell language grammars, an address of cell language structures, tools for cell language assessment, and an archive of elderly signers' interviews. Our research project aims at promoting the recognition of cell languages and contributing to a better understanding of the linguistic properties. Sinehub will have a direct impact on the implementation of policies for cell language and signers, as well as on the social perception and understanding of deaf communities. In most countries, deaf communities are marginalized within hearing societies. The language and culture is largely unknown and subject to false misconceptions and prejudices. In some countries, the national language is still lacking official recognition as a minority language. As a consequence, these deaf communities still do not benefit from their rights accorded to linguistic minorities. The project will have an impact on different aspects of the life of both hearing and deaf people. It will raise awareness within the hearing community of the linguistic and cultural presence of a largely ignored group. And it will mark a step forward in the fight for the recognition of the rights granted to linguistic minorities, which will greatly affect their political, educational, and social life. Specifically, Sinehub will provide society with resources that are necessary to boost sign language acquisition, teaching, and learning, to improve the interpreting training, to visualize minorities within a minority, and to document, valorize, and disseminate the richness of their cultural and linguistic heritage.
