Variation in voice onset time in stops in Gurindji Kriol : picture naming and conversational speech

Gurindji Kriol is the home language of children and adults under about 40 years of age in the traditionally Gurindji-speaking communities of northern Australia. Nearly all words in Gurindji Kriol are derived from Gurindji or from Kriol, both of which have been described as lacking a stop voicing contrast, at least in basilectal varieties in the case of Kriol. In this study, we describe variation in voice onset time in Gurindji Kriol, in both picture naming and in conversational speech by young Gurindji Kriol speaking women. For picture naming, Australian English comparison data are also reported. The results indicate that in Gurindji Kriol, VOT varies systematically in expected ways by place of articulation, and position in word and utterance, but not according to the phonological voicing category of cognate English words. Initial stops tend to have short-lag VOT of up to 30 ms; values can be longer in English code-switched forms. Medial stops tend to have negative VOT. The present data do not suggest a voicing contrast based on VOT.
