The videos and the annotations must be completed with information regarding the participants and their productions so that they can properly document LSFB and be used for research. This information is called corpus “metadata”. For confidentiality reasons, only information about the participants that is useful for consultation (age, gender and regional LSFB variation) are available to all users. If a participant would prefer that this information does not appear on the website, he/she can make a request to that end contact.
