Speaking Russian - problems
Sometimes I repeat the Russian phrase and it is marked correct. Other times despite repeating phrase twice I am moved onto the next question. I can't believe my accent is so bad if I frequently obtain correct for speaking a phrase and other times despite listening carefully several times and saying the phrase twice it is incorrect.
Worked for me. :) Do not feel bad. Just consider it an opportunity to practice speaking. Come to think of it, when I use Duolingo and no one is around, I usually say aloud every sentence in every exercise. Still, an audio exercise is a good reminder to practice your reading and pronunciation.
I personally think you should just turn off the microphone questions and try to read the questions out loud. Voice recognition is far from perfect and the best way to know if you're pronouncing things correctly is by conversing preferably with natives or at least someone whose studied Russian. I can tell you from experience practicing words on my own many times, thinking I'm pronouncing it correctly, only to find out from a native that I'm saying it wrong
