TheBiao language (Chinese:标话; also known asKang Bau orKang Beu) is aKra–Dai language (or perhaps three languages)^[2] spoken in southwesternHuaiji County andFengkai County,Zhaoqing,Guangdong. Autonyms arekaːŋ11peu̯55 andkaːŋ11paːu̯55.

Biao speakers are officially classified as ethnic Han by the Chinese government.^{[citation needed]}

LikeLakkia, the genetic affiliation of the Biao language within the Kra–Dai family is uncertain, although it could be asister of theKam–Sui languages.^[3][4] Hsiu (2014)^[5] suggests that Biao could either subgroup withLakkia, or form an independent branch ofKra–Dai on its own.

• /ʋ/ may also be pronounced as [w] in free variation.
• A labialized sound /kʷ/ may occur, but only in Chinese loanwords.

• 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)

The tone categories and contour-tone values for three dialects of Biao are (Liang 2002: 53):

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]

• Shidong 诗洞
• Yonggu 永固
• Dagang 大岗

Norquest (2021) classifies the Biao dialects as follows.^[7]

Yang (2012:73)^[8] provides the following lexical comparisons for five dialects of Biao.

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). InFengkai County, it is spoken in Chang'an 长安, Jinzhuang 金装, and Qixing 七星. TheFengshan 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 theFengshan County Gazetteer (1998) to be a distinct dialect from Biao ofHuaiji County. Yang (2011) reports that Biao is also spoken in Liandu 莲都 and He'erkou 河儿口镇 inFengkai 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).
