Speech perception systematic review (Hearnshaw et al., 2019)

Purpose: The aim of this study was to conduct a systematic review and meta-analysis to investigate whether preschool- and early school–age children with speech sound disorders (SSDs) have difficulties with speech perception.
Method: Systematic searching of 8 electronic databases identified 73 eligible studies across 71 articles examining the speech perception skills of children with SSDs. The findings and methodological characteristics of each study were reviewed, and the reporting of methodological information in each article was rated. A meta-analysis was conducted with studies that used the most common type of speech perception assessment task—lexical and/or phonetic judgment tasks.
Results: Across 60 of 73 studies, some or all children with SSDs were reported to have difficulties with speech perception. The meta-analysis showed a significant difference between children with SSDs and children with typically developing speech on lexical and/or phonetic judgment tasks.
Conclusion: Results from the meta-analysis demonstrate that children with SSDs have difficulties with speech perception. This appears to be the case for some but not all children with SSDs. The findings from this systematic review and meta-analysis also provide insight into the complex range of methodological issues involved in the study of speech perception in children with SSDs and the need for further research.
