Intelligent Computer-Assisted Language Learning (ICALL) has emerged as a game changer in vocabulary learning and language education by utilising artificial intelligence (AI) technologies to create personalised adaptive learning experiences. ICALL enhances vocabulary acquisition through personalised exercises, immediate feedback, and dynamic learning. The impacts extend beyond vocabulary enhancement, contributing to improved language proficiency, motivation, and self-efficacy. Moreover, ICALL’s broader implications for educational technology and pedagogy are meaningful, shaping future learning environments through adaptive learning and AI-driven tools like ChatGPT. These advancements encourage inclusive practices, support collective oversight, and align with evolving educational policies emphasising twenty-first-century competencies. As emerging technologies such as virtual reality and augmented reality are integrated into ICALL systems, they create engaging environments that meet diverse learning styles. With continuous study into areas like learner-centred AI applications, collaborative evaluation, and cognitive theories of language acquisition, ICALL is prepared to transform teaching practices, offering practical solutions that optimise vocabulary learning and overall language proficiency.
