Perception of Prosodic Speech Features: Final Intonation and Word Stress for EFL Learners

The acquisition of intelligible pronunciation in a second language (L2) hinges on successfully managing the perception and production of speech features. In this regard, prosodic speech features, particularly intonation and word stress are of critical importance. This study investigates the diagnostic perception test results of the learners of English as a Foreign Language (EFL) (N=125) in Turkish higher education context, analyzing their scores on intonation and word stress sections. The results reveal that participants performed better on identifying final intonation patterns compared to word stress items while both areas demonstrated certain challenges. Scores were lower for items with final falling intonation, particularly evident in interrogative wh- / how questions, suggesting complexities in processing this feature. Additionally, word stress accuracy decreased with increasing syllable count. No significant correlation was observed between intonation and word stress scores. These findings highlight the importance of recognizing intonation and word stress as distinct yet interconnected aspects of pronunciation, calling for effective instructional approaches to address these key components of L2 sound system.
