LANGUAGE PROFICIENCY ASSESSMENT DEVICE USING BRAIN ACTIVITY, AND LANGUAGE PROFICIENCY ASSESSMENT SYSTEM

摘要

This language proficiency assessment device comprises: a data acquisition unit that acquires measurement data for a to-be-assessed subject's brain activity that was measured when the to-be-assessed subject listened to speech in a specific language; and a determination unit that acquires machine learning results based on supervised learning data, in which measurement data for the learning subject's brain activity corresponding to an element of language comprehension measured when the learning subject listened to speech in the specific language is associated with the learning level of the learning subject with respect to the specific language, and that determines the learning level of the to-be-assessed subject corresponding to the element of language comprehension on the basis of the learning results and the measurement data for the to-be-assessed subject's brain activity acquired by the data acquisition unit.
