We are developing a Computer-Assisted Pronunciation Training (CAPT) system for learners of Icelandic as a second and foreign language (L2). Based on pre-designed tasks in pronunciation exercises, this system will provide corrective feedback on learners' speech. One of the main features we are implementing is a new method for automatic pronunciation scoring to provide immediate feedback on learners' errors. We report promising results for a pilot study of this method in Norwegian, where the pronunciation score successfully distinguishes between native speakers and adult learners, and we discuss how this method informs our continued development of Icelandic CAPT.
