Biao speakers are officially classified as ethnic Han by the Chinese government.[citation needed]
Classification
Like Lakkia, the genetic affiliation of the Biao language within the Kra–Dai family is uncertain, although it could be a sister of the Kam–Sui languages.[3][4] Hsiu (2014)[5] suggests that Biao could either subgroup with Lakkia, or form an independent branch of Kra–Dai on its own.
Sounds /m, ŋ/ may also occur as syllabic [m̩, ŋ̍].
/e/ only exists as a final with consonant ending in sequences /en, eŋ, ep, et, ek/. (Liang 2002: 36-42)
Tones
The tone categories and contour-tone values for three dialects of Biao are (Liang 2002: 53):

Dialects
There are three dialects of Biao (Hsiu 2014).[5] The Shidong dialect is documented in detail by Liang (2002). Additional data from the Yonggu and Dagang dialects are documented by Hsiu (2014). A sketch of Yonggu Biao phonology is also documented in Lin (2009).[6]

Liang (2002: 53–55, 61–62) lists the following comparative data for three dialects of Biao.
Varieties of Biao include the Shidong 诗洞, Yonggu 永固, Qiaotou 桥头, and Dagang 大岗 dialects (Liang 2002:3). In Fengkai County, it is spoken in Chang'an 长安, Jinzhuang 金装, and Qixing 七星. The Fengshan County Gazetteer (1998) reports that in Fengkai County, Biao (piau42) is spoken by 7,217 people in 48 natural villages in Chang'an 长安, Baoshan 宝山, and Dongshan 东山 townships. Fengkai Biao is reported by the Fengshan County Gazetteer (1998) to be a distinct dialect from Biao of Huaiji County. Yang (2011) reports that Biao is also spoken in Liandu 莲都 and He'erkou 河儿口镇 in Fengkai County, and Shatian 沙田镇, Hezhou, Guangxi. Comparative lexical data for 4 varieties of Biao spoken in Shatian Town, Hezhou (namely Fanglin 芳林, Dapan 大盘, Qiaotou 桥头, and Guishan 桂山) are provided in Chen & Yang (2011: 99-100).
Yang (2010)
According to Yang Biwan (2010), there are more than 160,000 speakers of Biao.[9]
Yang (2012)[8] notes that toponyms in Yonggu 永固 Township with the name “Luo 罗”, and toponyms in Shidong 诗洞 Township with “Liu 六”, “Feng 凤”, and “Nan 南” are of Biao origin.
