WITH THE ADVANCEMENT OF TECHNOLOGY, NUMEROUS POSSIBILITIES ARE EMERGING. FOR EXAMPLE, THE FIELD OF LINGUISTICS IS CLEARLY AFFECTED BY THESE TECHNOLOGICAL IMPROVEMENTS. THEREFORE, THE STUDY AIMED TO ANALYZE THE USE OF AUGMENTED ARTIFICIAL INTELLIGENCE FOR SECOND LANGUAGE (L2) ENGLISH LEARNING. FOR THE STUDY, PRIMARY DATA WAS COLLECTED FROM A SAMPLE OF 135 STUDENTS, AND A SEQUENTIAL MIXED-METHODS ANALYSIS WAS CONDUCTED.
