However, due to the lack of widely available research, this article will primarily describe the dialect known as Bulo Stieng spoken in the provinces of Bình Phước, Lâm Đồng, Tây Ninh in southwestern Vietnam and Kratié (Snuol District) and Mondulkiri provinces in adjacent areas of eastern Cambodia.

[3][4] Bulo Stieng is spoken in more remote areas of the mountains and jungles alongside its close relative, Mnong.

[3] Analyses which include the aspirated series as independent phonemes yield 33 consonants and a five-way contrast.

For the alveolar approximate, the trilled [r] is found in free variation with the flapped [ɾ].

The voiceless palatal fricative [ç] appears only in syllable coda as a complementary allophone of [s].
