Synchronous (Onsite) Exploring the Impact of AI-based Automated Pronunciation Evaluation Technology on Korean English Language Learners more

Sun, Apr 30, 14:00-14:25 Asia/Seoul

This study explored how automated pronunciation score feedback in a Computer-Assisted Pronunciation Training (CAPT) system impacted undergraduate L2 English learners’ pronunciation and motivation. The experiment involved the use of the CAPT system to provide multiple feedback (word-level, phoneme-level, and syllable-level) scores on the learner’s read-speech of English sentences, which contained phonemes Korean L2 English learners commonly make errors pronouncing. The learners practiced pronunciation with the CAPT system, and the effect of the score feedback was examined objectively and subjectively. In the objective analysis, pronunciation quality and motivation were measured using the score trend and the number of practices. In the subjective analysis, learners’ views on the system’s effectiveness for pronunciation and motivation were surveyed and analyzed. The results indicated that the CAPT system helped Korean L2 English learners improve their pronunciation and motivation.
