The Relationship among Speech Perception, Vocabulary Size and Articulation Accuracy in Children with Speech Sound Disorders
Ha Seung-Hee

Abstract
Objectives: The purpose of this study is to investigate the ability to perceive final consonants of children with speech sound disorders (SSD) in comparison with typically developing children age 4 to 6 years old. This study also examines the relationship among speech perception, vocabulary size, and articulation accuracy.

Methods: Thirty-three children with SSD and 35 typically developing (TD) children were asked to identify consonant-vowel-consonant one syllable words in whole words and gated conditions (-40 ms and -60 ms). The d-prime values were used to determine the children¡¯s ability to attend to fine phonetic details. Children with SSD were divided into two groups by comorbidity of language disorders and had their speech perception performances compared with TD children. A stepwise multiple regression was performed to investigate the relationship among speech perception, vocabulary size, and articulation accuracy.

Results: Group differences appeared in both whole word and gated conditions. Children with SSD and language disorders showed no differences when compared with children showing articulation problems only in the whole word and -40 ms gated conditions. Both SSD groups showed lower speech perception than TD children. In the -60 ms gated condition, only children with SSD showed significantly lower speech perception performances than TD children. Receptive vocabulary size and articulatory accuracy were significant predictors of speech perception.

Conclusion: The results suggest that children with SSD show deficits in speech perception and that the ability to attend to fine phonetic details is related to vocabulary size and articulation skills.
