Lingua Libre SignIt add-on for Firefox is a demonstrator project which allows you to translate a (French) word into (French) sign language videos on any web page. When you read a text and come across a word you don't know, select that word, click on the SignIt icon: the sign in LSF and the definition of the word in French will appear on a window.

If a word is not available in LSF, we invite you to record it with our easy-to-use webapp on LinguaLibre. The definitions come from the French Wiktionary to which you can also contribute.

Mission Edit

Lingua Libre SignIt aims to increase awareness and mastery of signed languages among the general public.

We believe signed languages have general benefits for everyone. The general public can easily gain the ability to communicate on longer distances, through glass windows, in overwhelmingly noisy environments. It would be more inclusive for signers, non-verbal toddlers (see baby sign language), and provide an important safety-net against hearing loss which affects nearly all our elders, some adults and children. We believe universal and transgenerational designs helps individuals and society to be more resilient, inclusive, peaceful and efficient.

Most needed skills Edit

  • Fluent signer(s), willing share is point of view on this nascent project, video record hours. Our tool will allow native signers to record around 200+ words per hour, adding them to the Wikimedia Commons' database and SignIt. A decent dictionary >3000 words can be built in just 10 hours. Those activists are the most valuable resource.
  • Web and JS developers, willing to code, discuss, improve the extension.
  • Language or country-specific project manager, willing to set up and organize with sign language activists some low cost video recording sessions.

Please share this call in your country and let get in touch when some volunteers are available, emailing Yug or on wiki talk page.
