In collaboration with DeafNet Silent Work has developed two sign language dictionaries for the international Deaf community in Africa. Both dictionaries are in 24 parts, these are 24 categories such as’ food and drink’ or’ tailoring’. One dictionary is in American Sign Language and the other in Arabic Sign Language. Both books are adapted for African cultures and environments and subtitled in French and Arabic. This material is part of our comprehensive teaching method Langue Colorée.
