Children with SSD are at greatest risk of delayed PA skills if they have poor speech perception abilities and/or relatively poor receptive vocabulary skills. Children with SSD should receive assessments of their speech perception, receptive vocabulary, PA, and emergent literacy skills.

English, French, and bilingual English‐French 17‐month‐old infants were compared for their performance on a word learning task using the Switch task. Object names presented a /b/ vs. /g/ contrast that is phonemic in both English and French, and auditory strings comprised English and French pronunciations by an adult bilingual. Infants were habituated to two novel objects labeled ‘bowce’ or ‘gowce’ and were then presented with a switch trial where a familiar word and familiar object were paired in a novel combination, and a same trial with a familiar word–object pairing. Bilingual infants looked significantly longer to switch vs. same trials, but English and French monolinguals did not, suggesting that bilingual infants can learn word–object associations when the phonetic conditions favor their input. Monolingual infants likely failed because the bilingual mode of presentation increased phonetic variability and did not match their real‐world input. Experiment 2 tested this hypothesis by presenting monolingual infants with nonce word tokens restricted to native language pronunciations. Monolinguals succeeded in this case. Experiment 3 revealed that the presence of unfamiliar pronunciations in Experiment 2, rather than a reduction in overall phonetic variability was the key factor to success, as French infants failed when tested with English pronunciations of the nonce words. Thus phonetic variability impacts how infants perform in the switch task in ways that contribute to differences in monolingual and bilingual performance. Moreover, both monolinguals and bilinguals are developing adaptive speech processing skills that are specific to the language(s) they are learning.

The purpose of this study was to compare the phonological awareness abilities of 2 groups of 4-year-old children: one with normally developing speech and language skills and the other with moderately or severely delayed expressive phonological skills but age-appropriate receptive vocabulary skills. Each group received tests of articulation, receptive vocabulary, phonemic perception, early literacy, and phonological awareness skills. The groups were matched for receptive language skills, age, socioeconomic status, and emergent literacy knowledge. The children with expressive phonological delays demonstrated significantly poorer phonemic perception and phonological awareness skills than their normally developing peers. The results suggest that preschool children with delayed expressive phonological abilities should be screened for their phonological awareness skills even when their language skills are otherwise normally developing.

This study examined the role of speech perception training in the correction of phonological errors. Twenty-seven preschoolers with phonological impairment who misarticulated /∫/ were randomly assigned to one of three groups: Group 1 children listened to a variety of correctly and incorrectly produced versions of the word “shoe”; Group 2 children listened to the words “shoe” and “moo”; Group 3 children listened to the words “cat” and “Pete.” A computer game was used to provide reinforcement for correct identification of the words. All children received the same traditional sound production training program for correction of their /∫/ error, concurrently with speech perception training, during six weekly treatment sessions. On post-testing, Group 1 and 2 children demonstrated a superior ability to articulate the target sound in comparison to Group 3 children. The results are interpreted in relation to previous research on this topic.

The two studies presented here examine the relationship between speech perception and speech production errors in children who have a functional articulation disorder. In both experiments, speech perception was assessed with a word identification test, based upon a synthesized continuum of speech stimuli, contrasting the specific phonemes that were associated with production errors in our sample of articulation-disordered subjects. Experiment 1 required subjects to identify words that contrasted the phonemes /s/ and /S/. In this test, adults, normal speaking 5-year-olds, and some articulation-disordered 5-year-olds identified the words seat and sheet appropriately and reliably. However, a subgroup of articulation-disordered children were unable to identify the test stimuli appropriately. Experiment 2 required a second group of subjects to identify words that contrasted the phonemes /s/ and /theta/. Although both adults and normal speaking children responded appropriately to the words sick and thick, in this test, none of the articulation-disordered children was able to identify these words appropriately. It is concluded that, for a subgroup of children who have a functional articulation disorder, production errors may reflect speech perception errors.

Maximizing children's vocabulary and speech perception skills before they begin school may be an important strategy for ensuring that children with speech-sound disorders begin school with age-appropriate speech and phonological awareness abilities.

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.

In this study, 48 children with moderate or severe delays in phonological ability received treatment for four phonemes, selected in accordance with either traditional or nontraditional target-selection criteria. Children who received treatment for phonemes that are early developing and associated with greater productive phonological knowledge showed greater progress toward acquisition of the target sounds than did children who received treatment for late-developing phonemes that were associated with little or no productive phonological knowledge. Between-group differences in generalization learning were not observed. Child enjoyment of therapy did not differ between groups, but parental satisfaction with treatment progress was greater for children in the traditional group than for children in the nontraditional group.
