Sign languages accept additionally developed alfresco schools, in communities with aerial incidences of deafness. Such languages accommodate Kata Kolok in Bali, the Adamorobe Assurance Accent in Ghana, the Urubú Assurance Accent in Brazil, several Mayan assurance languages, and bisected a dozen assurance languages of the acropolis tribes in Thailand, such as the Ban Khor Assurance Language.

These and added are all accepted isolates or baby bounded families, because abounding deafened communities are fabricated up of bodies who do not accept assurance language–speaking parents, and accept manifestly, as apparent by the accent itself, not adopted their assurance accent from added deafened communities during the generally recorded history of these languages.citation needed
