Creaky voice in Hanoi Vietnamese

This study investigates the variation in voice quality and pitch in different tonal sequences in Hanoi Vietnamese, in collaboration with Tạ Thành Tấn at the Hanoi National University of Education.

Hanoi (Northern) Vietnamese has a 8-tone system where tone and phonation are fused and with three glottalized tones: the mid-rising ngã tone C2 has creaky voice in the middle, the low-falling nặng tone B2 has accompanying creak with the low pitch contour, and the low-dipping hỏi tone C1 was found to have a more constricted phonation than non-glottalized tones (Brunelle et al., 2010; Kirby, 2011). Acoustic evidence has been shown in studies resembling different creaky voice types including vocal fry, laryngealization, and period doubling in its glottalized tones (Michaud, 2004; Brunelle et al., 2010; Kirby, 2011).

This project has received the GO.INVESTIGATIO Fellowship from the Austrian Academy of Sciences in 2024.
