La femme in Duolingo French talks too close to the mike, causing air to distort the sound. Being hard of hearing, it is very frustrating. I can understand sounds better on other french programs so will be quitting. Good program, otherwise. C
Sorry for your frustration. I take a reverse course and sometimes have to listen to my native language on slow speed because the sound is hard to hear!
Which other programs have better sounds?
I started a Swedish course which sounds just fine. I have no other complaints. Since it's free, I shouldn't complain, perhaps. C
