Speech sound disorder (SSD) and reading disability (RD) are both associated with impaired phoneme awareness (PA). This study explores how four measures of speech perception, tapping both segmental and suprasegmental processing, are related to phoneme awareness within 10- and 11-year old children labeled as SSD-only (n = 17), RD-only (n = 16), SSD+RD (n = 17), and age-matched Control (n = 16). In accordance with a multi-factorial theory of the relationship between speech perception and phoneme awareness, children in all three clinical groups were impaired on multiple measures of speech...
