Virtual reality can be used to learn foreign languages by immersing learners in cultural experiences and allowing them to practice with native speakers. It reduces anxiety while learning by providing a safe virtual space. Learners can visit realistic recreations of foreign locations and interact with avatars to practice pronunciation and language skills without traveling abroad. Popular virtual worlds for language learning include Second Life and open-source options like Kitely, which provide culturally authentic islands and events to engage in foreign language use.
