Siau (also called Sangir Siau or Bahasa Siau) is an Austronesian language of the Sangiric branch spoken by approximately 85,000 people on Siau Island and surrounding islets in the Siau Tagulandang Biaro Islands Regency of North Sulawesi Province, Indonesia. The language has a long history of Bible translation: the earliest New Testament was translated by Dutch Reformed pastor F.A. Kelling in the 1880s and published in 1883 by the British and Foreign Bible Society, with a revision following in 1901. The Today's Siau Version (TSV) is a more recent, contemporary-language New Testament produced to give the community access to scripture in a form more natural to modern Siau speakers. It is distributed as an audio Bible through Faith Comes By Hearing's Bible.is platform in both dramatic and standard audio formats, extending scripture access to a predominantly oral audience across the island communities of the Sangihe archipelago.
