Abstract
We investigated whether effects of prediction during spoken
language comprehension are observable in speech-motor
output recorded via ultrasound tongue imaging: Predicted
words can be specified at a phonological level during reading
comprehension, and listening to speech activates speechmotor
regions. It has been suggested that speech-motor
activation may occur during prediction of upcoming material
(Pickering & Garrod, 2007). Speakers model their own
upcoming speech, with the effects being observable at an
articulatory level in the form of anticipatory co-articulation.
We investigated whether the effects of prediction as a listener
can also be observed at an articulatory level. We auditorily
presented high-cloze sentence-stems, immediately followed
by presentation of a picture for naming. Picture names either
fully matched the omitted sentence-cloze item or mismatched
it at onset (e.g., TAP-cap-). By-condition differences in
picture-name articulation indicated that prediction of
upcoming material during speech listening can engage speechmotor
processes
