Weera Ostapirat splits the Buyang language into two branches:
North : Ecun and Langjia
South: Yalang
Ostapirat also classifies Buyang and Qabiao together as Eastern Kra, while Paha is classified as Central Kra. Together, the two branches form one of the two primary Kra branches, namely Central-East Kra. The En language has also been recently included in Eastern Kra. Li divides the Buyang language as follows: Eastern
The Funing County dialects of Ecun 峨村, Dugan 度干, Zhelong 者龙, Nada 那达, Longna 龙纳, Maguan 马贯, Langjia 郎架, and Nianlang 念郎. These villages are known collectively as Buyang Bazhai 布央八寨, or "the eight Buyang villages." Together, they make up the largest group of Buyang speakers, numbering about 1,000 speakers collectively. Li further splits the Funing County Buyang dialects into 3 groups :
Central Pohe Township 坡荷乡, Napo County, western Guangxi. More than 300 speakers reside in Rongtun 荣屯村 and Gonghe 共合村 villages, while over 100 live in Shanhe 善合, Yong'an 永安, and Guoba 果巴 villages; also in Renhe village 仁合村. 400 speakers total.
Western
In Guangnan County, Yanglian has around 500 Paha speakers, and Anshe only has about 100 speakers left. 600 speakers total.
Languages closely related to Buyang include Qabiao, En, and also Paha if considered a separate language.
Phonology
Diachronic evolution of consonants
Pre-Buyang, the stage in the evolution of the language that can be reconstructed from internal evidence, appears to have had a slightly different phonemic inventory than the modern dialects: a voiced stop *ɢ paired with *q, as well as voiced *ɦ alongside *h, and a pair of sibilants *s, *z. In addition, it doesn't appear to have had a series of aspirated consonants, a condition still found in the Ecun dialect. Thus reconstructed pre-Buyang is more similar in its phonemic inventory to reconstructed Proto-Austronesian than is any modern dialect of Buyang.
