Formosan languages
The Tsouic languages (also known as the Central Formosan languages) are three Formosan languages, Tsou proper and the Southern languages Kanakanavu and Saaroa. The Southern Tsouic languages of Kanakanavu and Saaroa have the smallest phonemic inventories out of all the Formosan languages, with each language having only 13 consonants and 4 vowels (Blust 2009:165). These two languages are highly endangered, as many Southern Tsouic speakers are shifting to Bunun and Mandarin Chinese.
