Audiovisual Asynchrony

ABSTRACTSpeech perception involves the integration of auditory and visual articulatory information, and thus requires the perception of temporal synchrony between this information. There is evidence that children with specific language impairment (SLI) have difficulty with auditory speech perception but it is not known if this is also true for the integration of auditory and visual speech. Twenty Spanish-speaking children with SLI, twenty typically developing age-matched Spanish-speaking children, and twenty Spanish-speaking children matched for MLU-w participated in an eye-tracking study to investigate the perception of audiovisual speech synchrony. Results revealed that children with typical language development perceived an audiovisual asynchrony of 666 ms regardless of whether the auditory or visual speech attribute led the other one. Children with SLI only detected the 666 ms asynchrony when the auditory component followed the visual component. None of the groups perceived an audiovisual asynchrony of 366 ms. These results suggest that the difficulty of speech processing by children with SLI would also involve difficulties in integrating auditory and visual aspects of speech perception.

Cognitive Correlates

PurposeLipreading and its cognitive correlates were studied in school-age children with typical language development and delayed language development due to specific language impairment (SLI).MethodForty-two children with typical language development and 20 children with SLI were tested by using a word-level lipreading test and an extensive battery of standardized cognitive and linguistic tests.ResultsChildren with SLI were poorer lipreaders than their typically developing peers. Good phonological skills were associated with skilled lipreading in both typically developing children and in children with SLI. Lipreading was also found to correlate with several cognitive skills, for example, short-term memory capacity and verbal motor skills.ConclusionsSpeech processing deficits in SLI extend also to the perception of visual speech. Lipreading performance was associated with phonological skills. Poor lipreading in children with SLI may be, thus, related to problems in phonological processing.

Performance Profiles

Many English-speaking children with specific language impairment have been found to be especially weak in their use of grammatical morphology. In a separate literature, many children meeting the same subject description have shown significant limitations on tasks involving the perception of rapid acoustic changes. In this study, we attempted to determine whether there were parallels between the grammatical morphological limitations of children with specific language impairment and their performance profiles across several perceptual contrasts. Because most English grammatical morphemes have shorter durations relative to adjacent morphemes in the speech stream, we hypothesized that children with specific language impairment would be especially weak in discriminating speech stimuli whose contrastive portions had shorter durations than the noncontrastive portions. Results from a group of eight children with specific language impairment with documented morphological difficulties confirmed these predictions. Several possible accounts of the observed morphology-perception parallels are offered.

Abstract Background Children with specific language impairment (SLI) fail to develop age-appropriate language despite being apparently normal in other respects. Those children usually have abnormal speech perception in noise. This work is designed to investigate speech perception in background noise in those children. It included two groups of children: control group (15 children with normal typical language development) and study group (25 children diagnosed with SLI). All children were submitted to intelligence scale, language assessment, full audiological evaluation, and Arabic Pediatric Speech Intelligibility in noise test (PSI). Results Results showed no statically significant difference in total and verbal IQ, while non-verbal IQ was significantly lower in the study group. As regard results of speech audiometry, the control group had better SRT and higher WD% than the study group. Expressive, receptive, and total language scores were lower in the study group. Arabic Pediatric Speech Intelligibility in noise test showed significantly increased PSI scores with increasing the SNR from 0 to +8dB in both groups. The comparison between both groups showed a significant higher score in the control group at different S/N recording conditions. Conclusions Children with SLI have difficulty in speech perception when compared to typically developed language children. This difficulty is more apparent in the presence of background noise.
