Development and assessment of an acoustics-based multisensory accent reduction system

Abstract

Technological advancements in the recent past have provided new methods for learning to speak English as a second language (ESL). The majority of accent reduction training regimes nowadays involve the use of different media as teaching and learning cues such as video or audio signals. However, few such programs have been proven to actually provide efficient and useful feed back to ESL learners, and few offers evidence proving that such multisensory approach of accent reduction is superior to traditional unisensory (auditory-only) approach. The present study intended to design and assess the effectiveness and efficacy of a multisensory, acoustics-based accent reduction training system that is capable of training foreign speakers to correctly produce English vowels by providing instantaneous auditory and visual feedback to the users. The study also validated the system against traditional accent modification regimes by objectively comparing the efficacy of such system with traditional accent reduction training. Results indicate that multimedia-based training with instantaneous visual and auditory feedback yielded significant improvement in accent reduction.
