Siouan languages
Authors who call the entire family "Siouan" distinguish the two branches as "Western Siouan" and "Eastern Siouan" or as "Siouan-proper" and "Catawban". Others restrict the name "Siouan" to the western branch and use the name "Siouan–Catawban" for the entire family. Generally, however, the name "Siouan" is used without distinction.
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.
