Notation and phonology of the Tri language in Vilabouly

Gérard Diffloth (1937–2023) was a leading authority on Austroasiatic languages, with a wide range of linguistic interests ranging from historical reconstruction to expressives, and much more. He was a tireless fieldworker who firmly believed that research into the linguistic history of Austroasiatic need be grounded in long-term fieldwork with native speakers in their daily speech environment. In this paper we introduce an unpublished manuscript on the phonology of the Tri language spoken in Vilabouly District, Savannakhet Province in southern Laos. We frame this with a brief introduction to his work, with a tribute to his commitment to fieldwork and the principles he maintained throughout the many decades of working with speakers of Austroasiatic languages.
