The purpose of this study is to investigate to what extent pronunciation features, which are segmentals and suprasegmentals, contribute to the listeners’ intelligibility of Korean elementary English learners’ read-aloud speech. It also aims to explore whether learners’ age and English proficiency mediate the contribution of segmental and suprasegmental features on the intelligibility. A total of 1,440 sentence-level pieces of read-aloud speech were collected from Korean elementary school students from 3rd to 6th grades. Three raters evaluated the read-aloud speech on their subjective understandability. Three types of assessments were given to the raters: ‘assessment of intelligibility,’ ‘assessment of suprasegmentals,’ and ‘assessment of segmentals.’ The collected assessment data was analyzed using SPSS 25. It is revealed that segmental features had a more significant impact on intelligibility than suprasegmental parts, regardless of learners’ age and English proficiency. Additionally, it was found that the younger the learners are and the lower their English proficiency is, the more segmentals took a significant role in listeners’ intelligibility.
