Western Siouan languages
The Western Siouan languages, also called Siouan proper or simply Siouan, are a large language family native to North America. They are closely related to the Catawban languages, sometimes called Eastern Siouan, and together with them constitute the Siouan (Siouan–Catawban) language family.
Siraya language
Several Siraya communities have been involved in a Sirayan cultural and language revitalization movement for more than a decade. Through linguistic research and language teaching, the natives are 'awaking' their mother tongue that has been 'dormant' for a century. Today a group of Siraya children in Xinhua District of Tainan particularly in Kou-pei and Chiou Chen Lin area are able to speak and sing in the Siraya language.
