Speech Modifications for Supporting Auditory Comprehension in Aphasia

Speaking “clearly” is a common strategy used to support auditory comprehension for people with hearing loss (Pichney, Durlach, & Braida, 1986). Recent preliminary research has also found that modifying speaking behaviors can facilitate comprehension for all people, not just those with hearing loss. This technique of using “clear speech” was shown to help people with language disorders following neurological impairment (aphasia) as well as the typical control adults. The aim of the present study was to further these findings by analyzing the benefits of using clear speech for people with neurological impairment and typical control peers in less than optimal listening environments (background noise). Although no significant differences were found in participant response accuracy or reaction time regardless of speaking style or listening environment, results of this study were limited by small participant numbers and simple stimuli that lead to observed ceiling effects
