Stop making sense: focus on sounds to help learn a language, study suggests
Learning a language may be easier when focusing on sounds rather than meaning, new research suggests. The study found that skilled linguists process unfamiliar speech sounds more like non-speech, which could help learners grasp new languages more effectively. This approach offers a fresh way to improve language acquisition.
