Designing CAST : a computer-assisted shadowing trainer for self-regulated foreign language listening practice Reza, Mohi

Abstract

Speech shadowing, i.e., listening to some audio and simultaneously vocalizing the words, is a popular language-learning technique that is known to improve listening skills. However, despite strong evidence for its efficacy as a listening exercise, existing software tools do not adequately support listening-focused shadowing practice, especially in self-regulated learning environments with no external feedback. To bridge this gap, we introduce CAST, a shadowing system that makes self-regulation easy and effective through four novel interface features — contextual blurring for inducing self-reflection on misheard portions, in-situ annotations for self-monitoring progress through tracking and visualization, embedded recordings for post-practice self-evaluation, and adjustable pause-handles for self-paced practice. We base CAST on a formative user study (N=15) that provides fresh empirical grounds on the needs and challenges of those who practice shadowing using conventional software tools. We validate our design through a summative evaluation (N=12) that shows learners can successfully self-regulate their shadowing practice with CAST while retaining focus on listening.
