Have you tried using the “Preview” feature to check the audio file for that phrase?
From the ‘Level’ page (Level 6 in your case) click on “Options”, then “Preview”, then scroll through the items in that level by clicking on “Next” until you reach the phrase you want.
If the audio file for that one is wrong, ask the Memrise German specialist (mario2189) to correct it. You can ‘tag’ him in your post by putting “@” in front of his username. It would be better to post in the forum topic for the course, using the link that Foorgol gave in the post above.
