UCL and Tohoku University study links auditory precision to language learning

A joint study by University College London and Tohoku University suggests that auditory precision—the ability to detect subtle differences in pitch, length, and tone—is a key factor in mastering foreign language pronunciation.

Research published in the Journal of Experimental Psychology: General involved Japanese learners of English. Using fMRI technology, researchers found that learners with high auditory precision processed unfamiliar foreign vowels by treating them more like non-speech acoustic signals. This approach allowed them to bypass the interference of existing native language patterns in the brain’s left sensorimotor system.

In contrast, learners with lower auditory precision relied more heavily on established linguistic templates from their mother tongue, making it more difficult to distinguish new sounds. The findings suggest that language education may be more effective if it focuses on developing a learner’s ability to hear fine acoustic nuances rather than relying solely on repetitive practice.
