Stop consonants in Yanyuwa and Yindjibarndi: Locus equation data

Locus equations are derived from F2 transition data for stop consonants in two Australian Aboriginal languages, Yanyuwa and Yindjibarndi, which have seven and six places of articulation, respectively. The slope values from these equations are used in order to determine the amount of anticipatory coarticulation between the consonant and the vowel in CV syllables. In accordance with results for other languages, the VELAR and the BILABIAL places of articulation are found to have very high slope values. The four CORONAL consonants are found to have lower slope values than thePERIPHERALS , although there is no clear pattern amongst the CORONALS themselves. Given that for these languages, there are no voicing or manner distinctions among the OBSTRUENTS, it is possible that the range of non-formant-based cues to place of articulation is wider.
