On the acoustic reality of “toneless” morphemes in Thai: Preliminary investigations from sequence-internal final particles

Main Article Content

Ratanon Jiamsundutsadee


This study aims to examine and compare between the F0 behavior of tonal final particles and that of toneless final particles in Thai when occurring inside the intonational phrase based on naturalistic speech data. The results reveal that tonal final particles have significantly greater average rate of change values than toneless final particles, along with more substantial variability in pitch range among toneless final particles. Interestingly, cases such as Tone 2 and L% FPs do not pattern with the general trend in terms of rates of change; regardless, pitch range variability still functions as a cue to their distinction. On the whole, these findings support structural analyses which make a representational distinction between the two types of final particles in Thai.
