Option to listen to native speaker on some excercises
I would love to be able to listen to the native speaker after I've successfully translated the excerpt from English to French (or any other language that we are studying). This would also be useful for the multiple choice questions as well.
This could be done by recording folks who are using Duolingo. You would periodically ask an English speaker, "Could you record this sentence for us?" That recording could then be compared with the other recordings of the same sentence, and the most "generic" recording would be picked; perhaps automatically by the system. The final recording would be played for everyone who's learning English.
