Automatic Speech Recognition System to Support Aural Vocabulary Learning

Vocabulary learning that overlooks the recognition of single sounds in English language learning could lead to communication difficulties, such as the inability to hear and pronounce English correctly. To address this issue, the vocalization strategy, in which students listen to the sounds of words and memorize them by voicing them, is considered a useful learning strategy and has been reported to influence performance in English language learning. Many studies have shown that self-regulated learning promotes the use of this strategy. In this study, we developed an English vocabulary learning support system using dictation-type speech recognition technology and evaluated whether it promotes the use of vocalization strategies and aural vocabulary knowledge.
