Ta’Oi (Ta’Oih, Ta Oi) is a Katuic dialect chain of Salavan and Sekong provinces in Laos, and in Thừa Thiên-Huế province in Vietnam (Sidwell 2005:12).


Sidwell (2005) lists the following varieties of Ta’Oi, which is a name applied to speakers of various related dialects.

  • Ta’Oi proper
  • Ong/Ir/Talan
  • Chatong is spoken about 50 to 100 km northeast of Sekong. It has been recorded only by Theraphan L-Thongkum.
  • Kriang (Ngkriang, Ngeq) is spoken by up to 4,000 people living in villages between Tatheng and Sekong, such as Ban Chakamngai.
  • Kataang (Katang) is a dialect that has been documented by Michel Ferlus, Gerard Diffloth, and other linguists. It is not to be confused with the Bru dialect of Katang.[3]
