The performance of 14 poor readers on an audiovisual speech perception task was compared with 14 normal subjects matched on chronological age (CA) and 14 subjects matched on reading age (RA). The task consisted of identifying synthetic speech varying in place of articulation on an acoustic 9-point continuum between / ba/ and /da/ (Massaro & Cohen, 1983). The acoustic speech events were factorially combined with the visual articulation of /ba/, /da/, or none. In addition, the visualonly articulation of /ba/ or /da/ was presented. The results showed that (1) poor readers were less categorical than CA and RA in the identification of the auditory speech events and (2) that they were worse in speech reading. This convergence between the deficits clearly suggests that the auditory speech processing difficulty of poor readers is speech specific and relates to the processing of phonological information.
