Comprehending Synthetically Accelerated Speech: the Relationship between Performance and Self-confidence

The present study examines the ability to comprehend speech presented at synthetically accelerated rates in an auditory display environment. We sought to determine whether listeners could accurately predict their own performance when listening to accelerated speech. Comprehension performance and selfconfidence ratings were compared at seven different rates of presentation. Self-confidence and accurate comprehension were related at slow to moderately accelerated rates of speech, however, listeners demonstrated an overconfidence effect at higher accelerated speech rates.
