Unlike other more widely studied Dai languages, Tai Ya has no traditional orthography, though it has a rich oral tradition.[3] Papers[4] have noted that this lack of orthography may endanger the survival of Tai Ya in future generations in Thailand, as the Tai Ya people shift towards the use of Northern Thai and Central Thai, due to the lack of literature in Tai Ya. However, it has been attested that language vitality as a whole (including the majority speakers in Yunnan Province) is high and "likely to be spoken by future generations".[3]
Dialects
Tai Hongjin can be split into five dialects, which are often mutually unintelligible (Zhou 2001:14).
The total number of Tai Hongjin speakers combined is 136,000 (Zhou 2001:14). A related but separate Tai language called Dǎi Jīnpíng (金平傣语) is spoken in Jinping County (金平县), Honghe Prefecture (红河州), which Zhou (2001) reports as having 15,400 speakers.[5] This language has its own traditional script as well (see Zhou 2001:379).
Heipu
Heipu 黑蒲 (autonym: Kalang 卡郎 kʰa³³lun²¹; also called Baiyi 摆彝 by the Han Chinese) is a variety of Tai Ya (傣雅) spoken by 118 people in the two villages[6] of Shitouzhai (石头寨[7]) and Xiaomiao (小庙[8]) in Panlong Township (盘龙乡), District 5 (五区), Xinping County, Yunnan (You 2013:268).[9] Heipu (黑蒲) is a Han Chinese exonym referring to their practice of teeth blackening. In Xinping County, the Heipu also refer to themselves as the Tai Kha (傣卡) (You 2013:336).[9] It is mutually intelligible with Tai Ya as spoken in District 4 (四区) of Xinping County. However, Heipu is unique in that it has only four tones, and has lost the final stops -p, -t, -k. Heipu is not to be confused with two other groups of the same name:
Heipu 黑蒲, an ethnic Zhuang group in Lijiang County, Yunnan with a population of 675 (You 2013:55).[9]
Heipu 黑蒲, an ethnic Bulang group in Mojiang County, Yunnan with the autonym Wa 娃 (You 2013:335-336).
