Learning the associations between letters and speech sounds is a crucial step in acquiring reading skills. Previous studies have found that the brain's process of linking letters and speech sounds is highly dynamic during initial learning and takes years to become fully automatic.

In this study, we first trained adult native Finnish speakers to associate novel foreign letters with familiar Finnish speech sounds. We then directly compared the audiovisual processing
