Pittayaporn (2009)

Pittayaporn distinguishes a similar group of Zhuang varieties as group "N", defined by the phonological shifts *ɯj, *ɯw → *aj, *aw. He moves the prestige dialect of Zhuang, the Wuming dialect, from the Northern Tai Yongbei Zhuang to Yongnan Zhuang - purportedly Central Tai - as it lacks these shifts. The various languages and localities Pittayaporn includes in group N, along with their Ethnologue equivalents, are:
