Thavưng or Aheu is a language spoken by the Phon Sung people in Laos and Thailand. There are thought to be some 1,770 speakers in Laos, largely concentrated in Khamkeut District. A further 750 speakers live in 3 villages of Song Dao District, Sakon Nakhon Province, Thailand, namely Ban Nong Waeng (in Pathum Wapi Subdistrict), Ban Nong Charoen, and Ban Nong Muang.[2]

Thavung makes a four-way distinction between clear and breathy phonation combined with glottalized final consonants. This is very similar to the situation in the Pearic languages in which, however, the glottalization is in the vowel.[3]
