 The preglottalized stops are truly preglottalized, not ejective or creaky voiced.The gammas have been described as fricatives, but here have been placed in the approximant row because of the preglottalized phone and the frequent ambiguity between dorsal fricatives and approximants.In several locations in the Sandu Sui Autonomous County, the preglottalized consonants and the voiceless sonorants do not exist, having merged with the other consonants.
