Research Abstract

Our previous research has revealed that L2 learners use acoustic cues that are not phonologically relevant for segmental perception in their L1. As a result, we have proposed a model for phonological perception we term the Category Activation Threshold Model. This model maintains that sensitivity to acoustic details not used for categorical distinction is actively suppressed in the course of mapping acoustic cues to phonological categories.
