To be more specific, the study attempted to probe which vowels that learners could be confused easily in speaking and listening. The results revealed that participants perceived the best in /i/-/I/ pair and /e/-/ae/ pair but the worst in /e/-/?/ pair, /?/-/ae/ pair and among /e/-/?/-/ae/ pair. They produced the best in the vowels of /I/ and /?/ but the worst in the vowels of /i/, /e/ and /ae/.
