I really like the idea behind the new 'click record and translate into [foreign language]' exercise type

Two obvious improvements are:

1. Adding hover over to the English sentence we are asked to translate (in case a user doesn't know a word)

2. Instead of just saying 'try again' if someone gets it wrong tell the user what you think you heard. You can give a few possibilities and say 'all these are incorrect' and you could look out specifically for incorrect translations users have typed in written exercises when using the same sentence. (I know it's way easier to get a computer to look out for a set of specific phrases rather than allowing it to search for any phrase, but by looking at typed answers you could create a bank of incorrect phrases to look out for too).
