Lingua Libre aims to make up for this lack of support by placing itself at the service of linguistic communities wishing to insert and promote their language into the digital space by exploring alternative means of communication to the written word, in the hope that this will free up online communication in a growing number of languages. This objective favours by its very nature regional minority languages that are poorly endowed in terms of oral or signed language, but also benefits more endowed languages that wish to highlight their oral and visual aspects. To fulfil its mission, Lingua Libre offers an online solution for mass recording, leading to the publication of a collaborative multilingual audiovisual corpus under free licence, whose vocation is information through consultation, and revitalisation by triggering the contribution of new language communities on Lingua Libre and then outside.
