Siraya language
Siraya is a Formosan language spoken until the end of the 19th century by the indigenous Siraya people of Taiwan, derived from Proto-Siraya. Some scholars believe Taivoan and Makatao are two dialects of Siraya, but now more evidence shows that they should be classified as separate languages.
