*Keynote Speakers*

*Weera Ostapirat (Mahidol University, Thailand)*

*Kra-Dai Rimes: System and Development*

In this talk, I outline a system of Proto-Kra-Dai rimes and discuss the
mechanisms of vowel development including the raising, lowering,
centralizing and diphthongization of the vowels. I will focus on how the
basic system of four reconstructed vowels *a,*ə, *i, *u, with length
distinction, has been shuffled in various Kra-Dai languages through the
influence of codas and penultimate vowels. Comparative notes on the
corresponding forms in Austronesian will be made.



*Pittayawat **Pittayaporn* *(Chulalongkorn University, Thailand)*

*Diachrony of Tones in Tai Languages*

This talk provides a state-of-the-art review of research on the diachrony
of lexical tones in Tai languages. First, we examine the reconstruction of
Proto-Tai (PT) tones, focusing on the "three-plus-one" system and competing
proposals for their origins. Second, we discuss etymological tone notation
systems that facilitate cross-linguistic comparison by referencing PT tonal
categories and the conditioning environments for splits. Third, we survey
splits and mergers of proto-tonal categories across Tai languages,
including the basic binary register split conditioned by onset voicing, as
well as subsequent splits and mergers that have created diverse modern
tonal systems. Fourth, we address phonetic changes in tonal contours,
demonstrating that tonal developments result from both phonetically
motivated internal factors and language contact.



*Tentative Conference Fees*

• Non-students (in person): approximately JPY 8,000

• Students (in person): approximately JPY 5,000

*Please note that the conference fees are tentative and subject to change
