Delayed auditory feedback (DAF) regarding speech can cause
dysfluency. The purpose of this study was to explore whether providing visual
feedback in addition to DAF would ameliorate speech disruption. Speakers
repeated sentences and heard their auditory feedback delayed with and
without simultaneous visual feedback. DAF led to increased sentence durations
and an increased number of speech disruptions. Although visual feedback
did not reduce DAF effects on duration, a promising but nonsignificant
trend was observed for fewer speech disruptions when visual feedback was
provided. This trend was significant in speakers who were overall less affected
by DAF. The results suggest the possibility that speakers strategically
use alternative sources of feedback.
