Abstract

The English past tense allomorph following a coronal stop (e.g., /bɑndəd/) includes a vocoid that has traditionally been transcribed as a schwa or as a barred i. Previous evidence has suggested that this entity does not involve a specific articulatory gesture of any kind. Rather, its presence may simply result from temporal coordination of the two temporally adjacent coronal gestures, while the interval between those two gestures remains voiced and is acoustically reminiscent of a schwa. The acoustic and articulatory characteristics of this vocoid are reexamined in this work using real-time MRI with synchronized audio which affords complete midsagittal views of the vocal tract. A novel statistical analysis is developed to address the issue of articulatory targetlessness based on previous models that predict articulatory action from segmental context. Results reinforce the idea that this vocoid is different, both …
