Kelabit is one of the remotest languages of Borneo on the Sarawak–Kalimantan border and spoken by one of the smallest ethnicities in Borneo the Kelabit people. Kelabit is notable for having a typologically rare series of true voiced aspirates along with modally voiced and tenuis consonants but without an accompanying series of voiceless aspirates. It is the only language known to have this phonation contrast which has been reconstructed for Proto-Indo-European. (See glottalic theory.)
