Voice onset times and burst frequencies of four velar stop consonants in Gujarati.

Voice onset times ~VOT! and burst frequencies of two aspirated ~i.e., /k /, /g/) and two unaspirated ~i.e., /k/, /g/! Gujarati velar stop consonants were investigated in an effort to provide characteristic acoustic information. Stop consonants in a monosyllabic vowel–consonant–vowel ~VCV! production were obtained from eight native speakers of Gujarati. Differences in mean VOT and burst frequency as a function of voicing and aspiration were examined. A significant voicing by aspiration effect was found for VOT (p50.026). The two voiced stops, while not significantly different from each other (p50.278), had significantly shorter VOTs than voiceless stops. The aspirated /k/ had a significantly longer VOT than the unaspirated /k/ (p50.0013). With respect to burst frequency, voiced stops had significantly higher burst frequencies than voiceless stops (p 50.002). There was no significant difference between mean burst frequencies of aspirated and unaspirated stops (p50.058). © 1999 Acoustical Society of America. @S0001-4966~99!00312-4#
