Problem on iPhone
The problem is with saying the words back. It was working fine in the beginning but now, even though I am saying the words correctly, I get the message "That still doesn't sound right" for EVERYthing. I do not have that problem on my MacBook.
I have seen this problem before. For the majourity of the time, it is very easily resolved. Try saying the words closer to your iPhone's microphone and say them as clearly and slowly as possible. Also, just to be on the safe side, check online or with a native Spanish speaker that you are definately saying the words correctly.
If this does not work, you should probably just change your Duolingo Settings so that you do not have to use the microphone in your course and seek Conversation Classes online or with a tutor. I would reccommend a tutor. Even though they are usually more expensive than having Conversation Classes online, they are in my opinion more effective.
Hope this helps! :)
Thank you for your response. I can well understand how you might think that I only THINK I am saying the words correctly, when in fact perhaps I am not. However, I do not have that problem on my computer....only on my phone. And yes, have said, slowly, clearly and close. It was fine the first couple of days but then, not.
