Participants

95% of deaf children are born of hearing parents, which is why signers are rarely native (and even more rarely second-generation native signers). Many signers learn LSFB in their first years of school (near-native signers). Others acquire LSFB as a daily language after the age of 7, or even when they were teenagers (late signers). The corpus represents these different profiles.

Other variables related to the signers that are equally present and comparable include regional, age and gender variations. The criteria used to select the pair of signers that would participate in a particular session are (in hierarchical order): linguistic profile, region, age and gender.
