title: Effect of phonemic perception training on the speech production and phonological awareness skills of children with expressive phonological delay.
abstract: Children with expressive phonological delays often possess poor underlying perceptual knowledge of the sound system and show delayed development of segmental organization of that system. The purpose of this study was to investigate the benefits of a perceptual approach to the treatment of expressive phonological delay. Thirty-four preschoolers with moderate or severe expressive phonological delays received 16 treatment sessions in addition to their regular speech-language therapy. The experimental group received training in phonemic perception, letter recognition, letter-sound association, and onset-rime matching. The control group listened to computerized books. The experimental group showed greater improvements in phonemic perception and articulatory accuracy but not in phonological awareness in comparison with the control group.
