Our main objective is to explore speech perception and production, their interplay and control, with a specific focus on language interactions in the bilingual mind. We aim to explore factors impacting speech production and perception in L1 and L2, including contextual properties (e.g., foreign accentedness of the speaker/addressee). We also focus on factors influencing and optimizing L2 speech sound and word learning (e.g., orthography, consciousness, cross-modality interactions). Another line of research targets bilingual language controlby exploring L1/L2 language interference in word and sentence perception and production in monolingual and bilingual (switching) modes. We recently started a large-scale ERC* project investigating the impact of the orthographic system on speech sound and word perception and production across modalities (listening, reading, speaking, typing), languages (opaque and transparent orthographies), and populations (monolinguals and bilinguals with varying reading skills). * This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (Grant agreement No. 819093).
