RT info:eu-repo/semantics/article T1 Assessing Pronunciation Improvement in Students of English Using a Controlled Computer-Assisted Pronunciation Tool A1 Tejedor García, Cristian A1 Escudero Mancebo, David A1 Cámara Arenas, Enrique A1 González Ferreras, César A1 Cardeñoso Payo, Valentín AB Over the last few years, we have witnessed a growing interest in computer-assisted pronunciation training (CAPT) tools and the commercial success of foreign language teaching applications that incorporate speech synthesis and automatic speech recognition technologies. However, empirical evidence supporting the pedagogical effectiveness of these systems remains scarce. In this article, a minimal-pair-based CAPT tool that implements exposure-perception-production cycles and provides automatic feedback to learners is tested for effectiveness in training adult native Spanish users (English level B1-B2) in the production of a set of difficult English sounds. Working under controlled conditions, a group of users took a pronunciation test before and after using the tool. Test results were considered against those of an in-classroom group who followed similar training within the traditional classroom setting. Results show a significant pronunciation improvement among the learners who used the CAPT tool, as well as a correlation between human rater's assessment of posttests and automatic CAPT assessment of users.
