There is a mistake in the French course
In the 'Feeings' section of the French course (Lesson 4) The female voice at one point clearly pronounces he word "fille" but the red 'Answer' panel corrects the input to 'fils' . Oooo ... so irritating!
If you spot a mistake, you can report it right away with the button on the left of the screen.
Yes slogger. I've noticed the same problem elswhere. To check pronunciation I've been using the Larousse French Dictionary App on my iPad. It's truly brilliant!
