Abstract

We investigated the role of the posterior tongue body in the articulation of the four-way coronal stop consonant series of the Australian language Wubuy. Significant tongue body posture differences between the dental, alveolar, retroflex and alveo-palatal stops were found. Further analysis revealed that the differences along the anterior-posterior axis were of the same magnitude as the difference between context vowel tongue back position and consonant midpoint position. Vowel tongue back position in the anterior-posterior dimension was predicted with a higher than expected accuracy by the consonant midpoint position, indicating a strong impact of the consonant on the vowel in Wubuy.
