Purpose: The aim of this study was to compare the nonword repetition performances and find out the correlation between the nonword repetition(NWR), speech perception(SP), and phonological memory(PM) children with speech sound disorder(SSD) and the children with typical development(TD). Methods: Twenty-six children participated in this study, 12 children with SSD and 14 children with TD(aged 5 to 6 years). NWR, SP, PM tasks were conducted for all participants, and the scores of NWR task were divided into the retrieval and sequencing. repeated two-way ANOVA was performed to examine whether NWR were significantly different between the groups and the syllable lengths. In addition, error patterns of NWR are examined. independent t-test was performed to examine whether SP and PM were significantly different between the groups. pearson correlation analysis was performed to examine the correlation between the NWR, SP, PM performances are investigated. Results: Significant group differences revealed in both retrieval and sequencing tasks. Children with SSD showed lower phonological working memory perfomances than children with TD. In the children with SSD, both retrieval and sequencing performances were related to phonological shor-term memory performances. Children with TD showed significant correlation between the retrieval and the SP performances Conclusions: This study is meaningful in that it examined the Processes before speech execution of speech in various factors, such as speech perception and phonological memory, and comprehensively looked at nonword repetition and related factors.
