Vowel devoicing as prosodic augmentation in Mebengokre

Abstract This paper explores an instance of prosodic augmentation ( Lovick 2023 : 382) via devoicing in Mẽbêngôkre, a Jê language spoken in Brazilian Amazonia. While segment lengthening is usually associated with prosodic augmentation, in Mẽbêngôkre high vowels can be devoiced, besides also lengthened, to express intensity. While all vowel segments in Mẽbêngôkre can be lengthened for expressive means, only high vowels /i ɨ u/ can be both lengthened and devoiced. This talk contributes to studies on expressiveness and iconicity in language by showing that vowel devoicing can also be targeted by prosodic augmentation.
