The course is to help foreigners to practise Hungarian pronunciation, concentrating on the more difficult vowel sounds first.
The course will prompt you with audio and you'll have to enter the Hungarian word by ear. If the meaning is given that is only additional information. The course is not designed to teach Hungarian vocab but to help with pronunciation.
Some levels are for practising individual sounds ('a' or 'á'), others help you learn how to tell them apart ('a-á' or 'e-é')
