Documenting isyarat lama Bali, an endangered sign language of Bali

We document two endangered signed languages: ISCENDO and ISLABALI. ISCENDO emerged in Indonesia's first deaf school (Cicendo) founded in Bandung, West Java in 1930. This critically endangered yet undocumented language is used by only 20-30 deaf people who attended the school in the 1950s and 1960s, before BISINDO (the national sign language) became prevalent. ISLABALI, used by older deaf signers across Bali, is severely endangered, as younger signers use a mix of BISINDO, SIBI (a sign system) and international sign languages acquired through contact with deaf tourists. Documentation is conducted by deaf and hearing Indonesians to build research capacity in-country.
