Creaky voice in Hanoi Vietnamese

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). Northern (Hanoi) 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).

This study thus investigates the different creaky voice types in the three Vietnamese tones using a elicited corpus.

The construction of the stimuli for the production study is nearly completed, with the help of a heritage Vietnamese speaker, Jillian Phan.
