It is spoken by the Saek people. Phonology The Saek tones are (Hudak & Gedney 2010): 1 = mid level, slight rise at the end 2 = low level 3 = falling to low, with glottal constriction 4 = high peaking 5 = high falling 6 = mid level, with slight fall and glottal constriction Saek tonal splits are as follows (See Proto-Tai language#Tones for clarification.). Locations Saek is spoken in the following locations (Hudak & Gedney 2010:251-252). Thailand Two Saek villages are "Ban Asamat" and "Ban Phai Lom," located just off the main river road a few kilometers north of Nakhon Phanom city. Another is Ban Ba Wa Saek, located further upriver, but inland a few kilometers. However, except for the older generation, the Saek language is all but disappearing as there is a strong tendency for younger generations to use the local trade language Lao/Isan, and/or the official Central Thai language as they are assimilated into mainstream Thai society.
